Dry September So far

3.8 mm of rain here so far this month though it is raining (lightly) at the moment. The front lawn has gone partially brown again though over the last week or so; there are dead patches that never recovered from the June/July drought. I will have to re-seed those areas.

Soil moisture at 30 cm is now the same as at the end of July. It was very windy, warm and sunny yesterday and the dust blowing around was something you don’t often see here in Blighty.

Looking at the rainfall radar, a possible 5+ mm to come.

I’ve noticed a few native trees are changing leaf colour. This is unusually early, possibly the earliest I’ve ever known. Normally you don’t really start to see any autumnal colour until well into October. Most of the photos I’ve taken over the last few years showing the autumn colour at its best have been taken early to mid-November.

August 2018 – The halfway point

A brief spell of heavy rain early this morning soon cleared (with a sharp clearance) to sunny intervals. Despite being told how much cooler and fresher I will be feeling because of it, the day was still warm and extremely pleasant with moderate humidity.

A maximum of 22.9C and nearly 7 hours of sunshine.

This August (1st – 16th) so far: warmer and wetter than normal; sunshine around the average.

Mean max = 23.8C
Mean min = 12.7C
Mean = 18.3C
Rain = 47 mm
Sunshine = 120 hours.

Cool Saturday, Humid Sunday

The summer has gone! Cool, drizzly and pretty miserable on Saturday with a maximum temperature only 17.5°C making it the coldest day since the 16th May.

Very wet overnight with 26 mm of rain then drier through Sunday morning before the sun made a welcome appearance and warmed it up a little. A humid maximum of 21°C.

Forecast is showing that summer will return but nothing like the pristine blue skies and +30°C temperatures we’ve become accustomed to over the last couple of months.

Real warmth & humidity ebbing away…..

Another lovely day with oodles of sunshine and warmth. A maximum of 25.5C and feeling a little humid with a DP of around 18C.

In the last couple of hours all that warmth and humidity has ebbed away and now replaced by something that feels decidedly cool. Stayed mostly sunny throughout the transition.

Temperature (now at 19:30) 18.3C, sunny with a DP of just 11.3C. I guess dinner later on will not be outside. That’ll be a novelty, eating indoors, who’d have thought.

I see the models are backtracking on a wet weekend for us here in the deep south and seem to be keen on bringing back something more usual for this summer; warmth and moderate humidity.

Really oppressive, sticky days have been few and far between this year with DPs mostly between 15C & 18C. That’s the same for the lack of any very high UV levels. Not even reached 9.0 this year, most unusual but not surprising given the lack of low pressure.

Sunny Sunday

A minimum of 12.6°C led into a day of unbroken sunshine and a deep blue sky. It was busy down on the beaches in Sidmouth, no wonder the sea felt warm, it was heated by all those bodies swimming in it.

A maximum of 26.0°C this afternoon. Humidity has been dropping away since the dew point peaked at 19°C around midday.

Summer nights

Sat outside last night until the early hours under the starriest of skies watching the first of the Perseids as they build to the peak expected on 12th & 13th. The warm summer night was alive to the sound of crickets chirruping away, it was all as beautiful as the stars above.

More Needed July Rain

A further 12.9 mm of rain today brings the monthly total to nearly the long term average with 42.9 mm. Even though rainfall is now just about normal for July, after a bone-dry June and with the higher temperatures and sunshine, the soil moisture deficit has been high. Given the forecast of a return to hot and sunny weather, today’s rain will probably have all but disappeared and made little difference by the middle of the week. Still, it filled the water butts!

The Warmth of July 2018

Yet another warm day with a maximum of 27.2°C. Still a week to go before the end of the month but the mean temperature is currently at 19.8°C. This is just 0.3°C below my all-time warmest ever month of July 2006. It is going to be close.

The warmth and humidity this afternoon brought out a wonderful sight of countless flying ants swarming up into the beautiful blue summer skies from their nests in the ground. What a stunning spectacle and something I haven’t seen on such a scale since I was a child.
