The green lung of Wanstead

The tree canopy cover map on the Mayor of London’s website reveals just how blessed Wanstead’s inhabitants are in terms of clean air relative to the proximity of the City.

Those living closest to the junction of Wanstead Park Avenue and Northumberland Avenue benefit most from Wanstead Park, Wanstead Flats and Bushwood.

Wild swimming in Wanstead Park?

Lewisham’s Beckenham Place Park will next year be home to a new wild swimming lake, thanks to a plan to make London the world’s first National Park City.lewisham pool

The scheme put me in mind of the Shoulder of Mutton lake in Wanstead Park which, decades ago, used to host swimming galas and other events. Long-time residents of Aldersbrook will remember the jetty and diving board that stood at the edge of the lake before falling into disrepair that led to their removal.

With millions set to be spent shoring up the dams of the park’s lake system it is surely feasible that the City of London Corporation can reopen Shoulder of Mutton to swimming while the work is undertaken.

While being cheaper than a lido it would provide an excellent resource and give local residents the chance to enjoy once more swimming in natural surroundings, just like in the Serpentine and Hampstead Ponds.

April 2018: four seasons in one month

I normally headline these monthly reviews by referring to the most notable weather but this April, often a fairly non-descript mid-spring affair, offered pretty much every type of weather. bluebells

The mean temperature finished 11.7C, 1.9C above average and the warmest for four years.

Rainfall was 55mm, 129 per cent of average and the wettest for 6 years.

Sunshine was just 110 hours, the dullest for 40 years and the 16th dullest since 1881.

Hidden in the positive monthly anomaly was the warmest April day in a local record going back to 1959: 29.1C on the 19th – a figure that represents a positive anomaly of 15.5C and occurring at the start of the warmest April heatwave since 2011. It was remarkable that such an anomaly happened so close to a record negative anomaly the previous month.

Yet, just over a week later, temperatures lurched cold again with one of coldest last days of April on record. Though the 24hr record wasn’t broken the noon-6pm record going back 60 years was beaten.

The wettest day occurred on the 9th with 10mm falling.

Air frosts: 0, Ground frosts: 1

April 30th provided a timely reminder after the heatwave to ne’er cast a clout till May is out. A low pressure system in the North Sea brought a thoroughly miserable day though even more rain fell across the Channel.

A new weather station for Wanstead

Wanstead has a new automatic weather station to complement the one set up in November 2012.Screen Shot 2018-02-13 at 19.13.20

The new AWS, situated in the grounds of Wanstead Golf Club, comes thanks to Friends of Wanstead Parklands. Data from the unit, which is sited very close to where Wanstead House once stood, will be used to help monitor the levels of the park’s lakes.

The sensor unit, 750m NNE of the weather station wansteadweather.co.uk on the Aldersbrook estate, is much better exposed and will hopefully offer more accurate wind and sunshine readings. It will also provide a chance to further investigate the area’s microclimate.

The station has already shown that the golf course is warmer on a radiative cooling night than the Aldersbrook Estate. Screen Shot 2018-02-18 at 14.22.08

The AWS can be found at WeatherCloud https://app.weathercloud.net/d0507444306#profile

Also at Weather Online
https://www.wunderground.com/personal-weather-station/dashboard?ID=ILONDON737

It also tweets hourly and provides an automatic 24hr daily summary. You can follow it @WansteadParkWX

Wanstead Weather: 2017 review

This year finished as the 10th warmest on record – some 0.7C warmer than the 1981-2010 average. Screen Shot 2018-01-05 at 12.54.53

Only three months of 2017 were roughly average – the means being within +/-0.7 every month, bringing the mean temperature to 11.9C.

Rainfall was less remarkable with the year finishing roughly average. The total of 607mm (101% of 1981-2010 average) puts it as the 119th wettest since 1797, just over 40mm wetter than 2016.

It was also a slightly duller than average year with 1,391.2 hours of sunshine recorded. That’s 94 per cent of average, the 91st sunniest since 1881.

Wanstead fairs well in London cold rush

Since the early hours of Sunday I’ve been tracking official sites around London to see how Wanstead fairs in terms of retaining cold temperatures and snow.

temp trace

The results, comparing hourly obs over 62 hours, show that Wanstead was a degree cooler than St James’s Park, half a degree cooler than Heathrow and marginally cooler than Northholt. Only Kenley, with its whopping 170m of altitude, was cooler.

While half a degree doesn’t sound much it can make all the difference, as we saw at the weekend when some areas recorded inches of snow while others barely a centimetre.

Though the snow has pretty much vanished now it was evident yesterday that the area was far more wintry neighbouring Forest Gate, Leyton and Stratford which had pretty much lost all their cover.

A report on the snow event can be found here.

* For anyone who has a fascination for the weather and whether their back garden in the Counties Estate is colder than their mate’s in the Warren Estate I notice that weather stations are now even cheaper and you don’t need to connect to the net via a dedicated PC. A unit from Ventus (the W830) allows you to connect to the amateur weather network Wunderground. The internet dealer Weatherspares has them on offer. (NB. I am not on commission but would be happy to offer anyone advice who wants to buy and set one up.)

December 10th 2017: rain turned to snow

Today’s snow came thanks to an area of low pressure that tracked further south than forecast.

Screen Shot 2017-12-10 at 17.38.33
Wanstead Park

‘Xanthos’ brought several hours of precipitation, 21.3mm in all to 3pm. Associated precipitation started as rain in Wanstead at 4am, turning to snow at 8am and quickly settling on all surfaces. By the observation time at 9am about 1cm had accumulated as the snow turned heavier.

Snow continued to fall through the day though, because soil temperatures are still relatively warm, the snow thawed from below and accumulations locally were restricted to around 5cms.

There is still a full, slushy cover on lawns at nightfall.

October 2017: warm, very dry and dull

October 2017 was a very dry month. Just 12.6mm of rain were recorded, the driest October since 1995 and the 11th driest since 1797.

The monthly mean finished 13.1C, 1.3C above average and the seventh warmer than average month this year.

Some 81 hours of sunshine were recorded, 76 per cent of average – the 4th duller than average month in a row. Just three months have been sunnier than normal in 2017!

Air frosts: 0, Ground frosts: 2

The first half of November looks like it will be predominantly anticyclonic. Expect lots of calm weather with the usual frost and fog.

July 2017: wettest since 1960

July 2017 was the wettest since 1960. Some 92.3mm of rain were recorded which is 212 per cent of the 1981-2010 average.finger cloud on 7th

Although the opening third of the month saw a continuation of the June heatwave temperatures gradually returned to normal values to leave the mean for the month at 19.2C, that’s 0.7C above average.

With all the rain sunshine totals were down. Some 167 hours were recorded, that’s 87% of average.

Though the rainfall total was impressive it is well short of the record of 164.2mm set in 1834, and is only 35th in the list going back to 1797.underlit

In terms of the rest of the summer a look at the ECMWF control run out to 10 days suggests an unsettled start to August with the jetstream centred right over the top of the UK. Things may improve as the Azores high attempts to exert more influence – so perhaps more in the way of sunshine than of late. In terms of heatwaves it is impossible to tell at this range.mid level

June 2017: very warm

June 2017 has been a month of real contrasts. A thundery deluge on the 2nd was followed by conditions typically brought by the European monsoon.

24hr rainfall totals

Warm weather followed in the second week before a full-blown heatwave arrived bringing the hottest June spell since 1976.

The mean temperature for the month finished at 18.9C, that’s 2.8C above average. It was the second warmest June in a local record going back to 1797. Though it was only 0.4C cooler than 1976 it was also much wetter than that very dry month.

Though it appeared a wet month, over two-thirds of the recorded rain fell in two episodes.

Sunshine for the month was 202.3hrs, 114% of average.

In terms of the rest of the summer you would be forgiven for thinking that we have already had more than our fair share of good weather. One way of looking at it is to count the number of days the mercury rises above 25C with 10 hrs of sunshine. Since May that has happened on 13 occasions – far higher than anything in the past four years.june heat

It will be interesting to see if July and August, normally the months where we get most of our summery weather are as good as June.
