Cool summer

Postby Len Wood » 2015 Aug 12, 19:11

This summer has not been especially warm here in SW Devon.
Today we reached a pleasant max of 23.1C, the warmest day since 26.2C on 30 June.

We are having a heatwave-less summer.

More an average summer here in Farnborough, so far.
June was warmer than average, sunny and dry.
July was almost spot on average temperature (warm start, cool end). It was wetter than normal but only because of 32mm falling on the 24th. Somewhat cloudier than average too.
August so far has not been bad, temp close to normal and every day so far with a max >20C. Only 7.7mm of rain to yesterday (with 10mm so far today in thundery showers).

Certainly I have found the summer generally pleasant, maybe a happy medium between the cool wet weather of Scotland and the baking heat over central and eastern Europe!

Hi Greg, hi Len

I've just returned from a scorching continent - they've been experiencing one of the most extreme heatwaves since July 2006 / summer 2003, or even hotter in places. One can see the huge contrast in recent European temp anomalies on this NOAA map:
http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/regional_monitoring/1ctan1.png

Our cool temps are surely related to the strongly negative SSTs across the middle of the North Atlantic at present, as long as there is a W/SW flow:
http://www.esrl.noaa.gov/psd/map/clim/sst.shtml (scroll down to 'ANOMALIES')

Back in Stornoway, I was shocked to see the 'high' temp whilst I was away was only 17degC, with a min of 5degC!

July 2015 Stornoway stats:
Another poor month in Stornoway, very wet, cool and dull again. Three separate funnel clouds were spotted during the month (see photo of one from 12th below):

A cool Summer up here too.

JJA has been below average. In fact looking at my records the anomaly has been below average all year, and I have yet to finish a month in 2015 with an anomaly in positive figures.

Mean for August so far (after 18 days) is 16.2c (-0.6c). Today was cool as well with a screen maximum of 14.1c. Also had my coolest grass minimum yesterday morning (17th) with a minimum of 3.5c, my coolest August grass reading since 2003.

Had my wettest day of the year so far with 19.1mm of rainfall since 2400 UTC, been raining most of the day, still raining at 2100 UTC.

Not only cool, but also becoming wetter than average here.
June, July, August average here is 187 mm.
Have had 221 mm so far with 12 days to go.

Wet days have been really wet, as today with 20.6 mm.
Sunshine is below average.

There have been some pleasant days, so it has not been all bad for the masses of holiday makers we get down here in the summer.

After a sunny and dry start it is now becoming a dull and wet summer.

This afternoon's sunshine has done little to stop this August from being very 'dull' month so far. Monthly sunshine total now up to only 115 hours. It has also been extremely wet and as with July, the majority of that rain falling in the 2nd half of the month. Total monthly rainfall to date stands at 124.5 mm.

Summer rainfall (to 23rd Aug) is at 227 mm and sunshine now at 545 hours.

I thought this year could end up being another 2000+ hours sunshine year but this August is likely to scupper that unless the autumn and winter are rather sunny.

Annual sunshine total now at 1336 hours.

Started off well and has gone progressively downhill.

To compare with your figures Nick, Camborne sunshine just a miserable 102 hours up to 23rd. Camborne is a cloudy spot, but even on favoured coasts the figure is probably only 120 hours or so. Last August, certainly not the best of months, Camborne managed 200 hours, Bosullow just NW of Penzance on the moors 220.4 hours.

My total rainfall to date is 115.8mm.

Summer
Rainfall (to 23rd August) is 279.1mm.
Total sunshine at Camborne 497.4 hours. I'd estimate nearer 550 right on the coast, fair weather land based Cu have been even more a feature than normal this year. Last summer Bosullow saw 745.9 hours, Camborne only a little less.

Temperature wise it's now a distinctly cool summer. June -0.2C, July -0.5C, August (so far) -0.8C.
