The Met Office, earlier this week, warned us that extreme summer rainfall may become more frequent in the UK because of climate change. The research, produced in collaboration with Newcastle University, says that while summers are expected to become drier overall intense rainfall producing serious flash flooding could become several times more frequent.
I hadn’t thought much about the story until, as part of my attempt to find out what this summer is going to turn out like, I discovered some fascinating details of several events during the summers of 1811 and 1828. Many have remarkably similar characteristics to the Boscastle flood in 2004 – the kind of episode the Met Office tells us could become far more common by 2100.
The entries for 1811 in Luke Howard’s book The Climate of London once again shows that extreme weather is nothing new and serious flash flooding was actually more common all those years ago.
May 20 1811 A severe thunder storm came on at Ingatestone, Essex, accompanied with a deluge of rain. In ten minutes the water ran about three feet deep in the streets. The same night at Potter street on the road to Newmarket hailstones nearly as large as pigeons eggs fell accompanied with the most terrific thunder and lightning.
May 27, 1811 Hereford: We were visited by a dreadful storm of thunder and lightning accompanied by torrents of rain very destructive eastward of this city. It commenced about three o’clock in the afternoon and continued with little intermission till past eight. This storm and the consequent inundation of several thousand acres of land destroyed a number of lives and much property.
June 8, 1811 A severe storm of rain hail and lightning took place in Birmingham and the neighbourhood. The hail or rather pieces of ice which fell are described as of prodigious size and considerable damage has been done to the windows. Worcester this day another most tremendous storm of thunder lightning and rain took place about 11am equal to that of the 27th except the hail.
A storm was also experienced June 28 at Bury and its neighbourhood. The lower part of the houses were filled with water which lay in the street 5 feet deep. The hail stones 5 8ths of an inch in diameter broke near five thousand panes of glass. About twenty six head of cattle were killed last week by the lightning at Bisby and Walsham in Norfolk.
July 2, 1811 In the neighbourhood of Wonersh near Guildford after one of the most sudden strokes of thunder a deluge of rain took place so instantaneously as to carry away or destroy every thing which impeded its progress. The damage is estimated at not less than 1,500.
July 21, 1811 A heavy fall of rain did much damage at Stamford. In the meadows about Barrowden, Wakerly, Harringworth, Thorpe, Caldecot and Bringhurst immense quantities of hay were carried away. Several thousand loads it is supposed have been destroyed in addition to which the injury sustained by the land has been very great. The water rose thirteen feet in less than four hours in Wood Newton parish.
In 1828, a spring that was also similar in terms of temperature and rainfall to this year, more entries in Climate describe flash flooding events.
July 8, 1828 Extensive rains on Tuesday afternoon the 8th instant about four o’clock a storm of wind rain and hail accompanied with thunder and lightning broke over the town and neighbourhood of Taunton with a degree of violence never before remembered by the oldest inhabitant. The thunder in heavy peals was heard simultaneously from the east and west and the wind at one period of the storm blew a perfect hurricane. At Kingston the banks were thrown down for several miles and three rams the property of Mr Welch valued at thirty pounds were killed by the lightning. The corn is sadly levelled by the storm. The hailstones were of uncommon thickness and in their descent destroyed much glass in the windows of private dwellings and outhouses. Various statements of mischief have reached us from our correspondents for many miles round all representing the storm to have been of unqualified violence. Taunton Courier
The inundations occasioned by the constant heavy rains in Flintshire and Denbighshire have proved most injurious and in some instances destructive to the iron works in those counties. The Coed Talon works belonging to the Welsh Iron Company have sustained very considerable injury, the bridges, dams and culverts belonging to those works were all carried away by the tremendous torrents and bursting of the springs. On Thursday night week the waters in the immediate vicinity of the works rose to the extraordinary height of 22ft above their ordinary level and in a few hours extinguished the furnaces such was the impetuosity of the flood and the influence of opposing elements of fire and water that the most serious apprehensions were entertained that the furnaces would have been blown into the air.
Happily the buildings sustained the shock and no lives have been lost. It is stated by the oldest inhabitants in the neighbourhood that such awful effects from impetuous torrents were never before witnessed by them. Throughout a great part of Oxfordshire and Worcestershire the wheat and barley have suffered considerably by the late heavy rains Friday afternoon, a solitary dark cloud passed over the north end of Winchester towards the valley of Itchen Abbas the sun shining from the opposite part of the horizon. The spot whereon the cloud appeared to rest seemed to be enveloped in total darkness whence shot a stream of electric fluid accompanied by a short but tremendous crash of thunder and hailstones of considerable magnitude. So violent was its force that it killed two fine horses belonging to Mr Twitchen of Itchen Abbas and struck the carter to the ground where he lay in a state of insensibility for some time, his frock was singed by the lightning. About the same time a cottage occupied by the shepherd of Mr Twitchen s brother at Mitcheldever experienced its violence by being greatly shattered and the shepherd’s wife struck instantly dead. During the same day three horses belonging to Mr Budd of Hatch Warren Farm, near Basingstoke, were struck dead by the electric fluid and a man who had charge of them was so dreadfully injured as to render recovery hopeless. Bath Chronicle
The list goes on… I’ve had a look at all summer rainfall since 1797 to see if 1811 and 1828 were particularly wet years but the records I have, taken by Luke Howard at Stratford, are nothing out of the ordinary.
The summer of 1811 in London saw a mean temperature of 16.1C (1.5C cooler than the current 1981-2010 average) while rainfall was 211mm (just under 150% of the current average). The summer of 1828, however, was warm for the period – at 17.5C. Rainfall was high at 317mm (218% of today’s summer average). Of course totals in the areas affected in the articles would have been much higher.
So when the Met Office says climate change is going to bring more flash flooding in summer I wonder if it is the climate cycling back to a period where we’ve seen it all before.
*For those interested below is a continuation of summer flooding events that plagued the country in 1811, 1828 and possibly many other events of records we have probably sadly lost.
Sussex The accounts from the western part of this county both on the coast and in the weald concur in stating that the effects of the thunder storm of the 3rd instant were most severely felt. So severe a storm has not been experienced since 1821. The storm on the evening of Thursday night was most violent in the neighbourhood of Chichester and lasted from eight in the evening till nearly four in the morning, the electric fluid entered a cottage at Birdham and shivered a bedstead rolling its occupier with the bed on the floor lut who escaped without injury.

The almost constant rain which has been experienced in Penzance and its neighbourhood has been very detrimental to the hay harvest West Briton PL
July 10, 1828 We regret to state that the floods in this neighbourhood still continue and the waters indicate by their colour how great the mischief is amongst the hay. The Welland and the Nene are of the hue of strong tea proceeding from the essence of the hay which is entirely washed out of whatever was not stacked before the 10th instant. – Stamford Mercury
Cambridge The late heavy rains in this part of the county have laid and much injured the corn crops and likewise considerably impeded the hay harvest Bury Herald
July 17, 1828 Sheffield In our last publication we alluded to the long continuance of hot weather which had been experienced in this neighbourhood. On Tuesday, however, a change took place and on Wednesday the rain fell more heavily and incessantly than it is remembered to have done at the same season for several summers past. Indeed not only were our two rivers remarkably high but the springs of many wells which had failed at the usual time experienced a temporary refluviation. Sheffield Iris, July 17
Malton, July 17 Every hour brings fresh accounts of the extensive losses sustained by the occupiers of land bordering on the Rye and Derwent. Hay has been floating in swarth and in cock of all sizes and the loss in various kinds of grain and potatoes is incalculable. Such a weight of rain and such a flood were never known at this season of the year. On Sunday morning last Sunderland was visited by a thunder storm. The lightning was remarkably vivid the peals of thunder were tremendous and the rain fell in torrents. The Wear was also much swollen. Great quantities of hay came down the river. From our correspondent at Durham dated Sunday afternoon: Since early on Saturday morning Durham and the neighbourhood have been visited with a succession of heavy rains insomuch that the river Wear is swollen to a dreadful height and has done and is still doing frightful damage to the adjacent fields which are overflown to the extent of many hundreds of acres many of which are meadow some just mown some in pike and some standing uncut – Tyne Mercury PL, July 17
Doncaster, July 19 I have within a few days been over a considerable tract of land in this and the adjoining county for the purpose of ascertaining the effects of the late floods on the crops. A great portion of the country through which the Derwent runs as well as the other rivers which empty themselves into the Humber has been overflowed to a very considerable depth and the consequence has been the complete destruction of the greater part of the grass which was cut and those crops which were not cut will not be worth the trouble. We regret to state that in this town and neighbourhood the weather has continued extremely unfavourable throughout the week. Scarcely a day has passed in which we have not been visited by heavy falls of rain accompanied in some instances with thunder and lightning. We have not heard of any further injury being done in the vicinity by floods but we fear that the wheat and other crops as well as fruit and vegetables will suffer greatly from the long continuance of wet weather. – Manchester Mercury PL, July 20
Although within the last few days several thunder storms have fallen in this immediate neighbourhood we have not heard of any serious injury to life or property. On Wednesday week 9th at Great Houghton during a thunderstorm the lightning descended through the sky light which it destroyed in the roof of Mr Brook’s house and through the ceiling into an upper apartment and shook down the tester of the bed on which Mrs Brook was reposing without, however, inflicting any injury further than the alarm into which she would naturally be thrown. Its course was then along a passage in which there was a cupboard whose contents of glass and earthenware were partly demolished and the door of the cupboard dashed along the passage at the extremity of which was a young female who happily escaped unhurt. – Doncaster Gazette PL, July 21
Newark July 21, 1828 You cannot possibly have an idea of the effects of the late stormy weather and the consequent inundation of the large tract of country unless you were to see it. All the country from this place situated on the banks of the Trent down to the Humber has been completely overflown and has borne the appearance of one expansive sea.
Bedford July 22 In consequence of the dreadful and continued rains every thing in the neighbourhood of this town is in the most frightful state. The Ouse has overflowed its banks in every direction as well below as above the bridge and for miles nothing is to be seen but a weary waste of waters with islands of hay or haycocks. The early season for hay gathering in the northern counties was favourable in the extreme and a great quantity of hay out of the abundant crop was secured in capital condition. About the middle of the last week the barometer sunk rapidly and torrents of rain fell day after day till the rivers became swollen and on Sunday and Monday last vast tracts of land particularly in the southeast part of this county extending from Doncaster to Hull were inundated. Even in the neighbourhood of Wakefield the hay was seen floating in the fields and near Barnsley a great deal was either washed away or rendered useless except for litter. The corn crops have also been much beaten down by the heavy rains and potatoes in low situations have suffered from the floods. – Leeds Mercury
Whitby From the 8th to the 13th instant a succession of heavy rains has been experienced at Whitby and its neighbourhood which did considerable damage to the bridges on the Esk. On Sunday morning the platform of the elegant suspension bridge at Ruswarp belonging to James Wilson Esq MP was wrenched from its abutments and together with the cast iron pillars was thrown into the stream. The small stone bridge recently erected by Edmund Turton Esq on the new line of road was also carried away likewise a bridge at Cock mill and another in the neighbourhood of Egton. The neat bridge at East Row has been so far injured as to be passable only by foot passengers. Great quantities of timber, hay were washed away and the fields and gardens completely flooded. From all parts of the country accounts pour in of the disastrous effects produced by the late uncommonly heavy rains. From Ganstead and Withernwick in Holderness to beyond Driffield a distance of from twenty five to thirty miles the country presents an almost unbroken sheet of water. The quantity of hay corn and potatoes destroyed and likely to be so is beyond all calculation thousands of acres of the latter are literally rotting in the ground. From Doncaster down to Gainsborough and the low grounds at the junction of the Ouse and Trent the inundation is stated to have been still more destructive than in this immediate neighbourhood. – Hull Advertiser
The south western districts of Scotland appear to have been visited by the same excessive quantity of rain that has been experienced so generally over England. It would appear, too, that the crops there are in general good and that the wheat in particular promises to turn out better than in the south July 30.
Deal Aug 9 The wind has blown very hard the whole of this afternoon at intervals almost a hurricane. Wind WSW
Brixham (Torbay) Aug 9 At three o’clock this morning it came on to blow quite a hurricane from the SSW and continued unabated until four this afternoon since when it has been more moderate.
Falmouth Aug 9 It blew a heavy gale here last night and continued until noon this day from the SSE to WSW
Penzance Aug 9 The wind has blown a perfect hurricane from SW all this morning. Accounts of damage.
Noon. PL The storm still continues with unabated fury. Great numbers of trees have been blown up by the roots and many mows of corn in the fields are quite upset and the sheaves blowing about in all directions PL
The Thames was higher on Wednesday last than has been known at this season for twenty seven years. All the low land about Goring Pangbourn Mapledurham, Caversham, Sonning &c was under water. – Berkshire Chronicle
