Another temperature record

The thermometer here has passed 32.4C, our previous overall temperature record set in July last year – it’s reading 32.8C as I type this at 1540 and it does look as if it may have peaked, but there is still time for an even higher reading.

It’s remarkable that this record has been broken in June. Although this month has the longest days, overall temperatures are usually a degree or so higher during July and August. We had never recorded 30C in June at this station before the current hot spell, and now we have reached it three days in a row – and a near-miss of 29.7C on the 18th.

Things should be back to normal tomorrow as the high pressure system that has generated this heat drifts off east, and that will be a welcome relief to many. There’s the outside chance of a thunderstorm to see it off, too.




Temperature records tumble

The temperature reached 30.6C at 1736 today, a new record for June at this station. It has also been our warmest June day (0600-1800) with an average temperature of 26.3C, and the second-warmest day overall since the station was set up in 2007 (the warmest was 19 July last year, when we also recorded our all-time record high temperature of 32.4C).

As I type this at 1815 the thermometer is hovering just under 30C and showing no sign of falling just yet. Yesterday evening a sea breeze popped up at about 1900 to cool things off a bit so, maybe we’ll get a little relief today as well – but we’re heading for a warm night.

Incidentally, we might be heading for a very dry month as well – we’ve recorded just 10.4mm so far, and this warm weather is set to remain for a few days yet.


EDIT 20/6/17

Yesterday’s high temperature record for June didn’t last long – we recorded 31.3C this afternoon.



May 2017 summary

This was the warmest May since 2008 with an average temperature of 13.6C, about a degree above normal for this time of year. Rainfall was above average but not exceptional at 64.8mm, with the wettest day being the first with 11.8mm – the same total as we recorded for the whole of April. The following day saw the start of the longest dry spell of the month, with no rain recorded from the 2nd to the 10th thanks to a persistent easterly breeze. Talking of wind, it was a quiet month with a maximum gust speed of 24kts.

Thunderstorms were in evidence on three occasions during the month, with rolls of thunder audible from a storm to the east on the afternoon of the first, a brief storm bringing an end to that dry spell on the afternoon of the 11th, and a spectacular light show around 3am on the 27th when a line of thunderstorms stretching from here to the Isle of Wight lit the sky to the south east. That was, incidentally, the warmest May night we have recorded, with an average temperature of 19.3C – not conducive to sleep.

The highest temperature of the month was 26.7C on the 26th, a day of almost unbroken sunshine – and the source of energy for those thunderstorms the following morning. This wasn’t the only sunny day, with good periods of sunny weather around the 10th and the 19th.

Apart from that dry spell for the first week or so of May, there was no dominant weahter pattern and we alternated between spells of high and low pressure, bringing a mix of weather.

May brought to an end our joint-warmest Spring, with an average temperature of 10.8C matching the figure for Spring 2011. Total rainfall was 125.8mm, below average but with the exceptionally dry April being partially offset by the above-average total for May.
