July 2005 Summaries

[Polar Continental]

Hi everyone,

Posting early as on hols shortly.

July 2005.

My records up until the 29th.

The first week saw changeable conditions with temperatures rather below average, but with a couple of pleasant days.

From the 9th we saw quite a prolonged heat wave over most of the country, as high pressure became centred over the UK, this stuck around for around 8 days. I recorded a maximum temperature of 30c on the 10th and again on the 14th, quite high temperatures really as the heat was home grown, not imported heat.

I also recorded some very warm nights during this period, a minimum of 18c on the night of the 11th / 12th.

By the 18th low pressure approached NW Scotland bringing a breakdown of the warm settled conditions. Later low pressure also approached the UK from the southwest, bringing very wet conditions for virtually all-southern areas of England. Unfortunately the low pressure virtually parked over southern areas and put an end to any hopes of good weather for the rest of the month, most of the country was cool cloudy and felt autumnal for a time.

Have put figures in below, as I don’t think they will change much now.

Average maximum temperature =

Average minimum temperature =

Mean temperature, current = 16.6c +0.1 above average

Warmest day on the 10th & 14th = 30c

Coldest day on the 25th = 14.7c

Warmest night on the 11th / 12th = 18c

Coldest night on the 5th/ 6th = 8.4c

Rainfall total = 50.8mm

Overall a slightly wetter but significantly warmer than average July, only missing out on July 2003 by 0.3°C. It was a month of three parts. The first third of the month was relatively cool and wet, with 50mm of rain recorded from the 1st to 6th. The 2nd saw the highest minima of the month, falling no lower than 16.5°C. However, 3 days later the temperature failed to climb above 16.6°C.

The second part of the month saw a prolonged hot spell, the best on my records in this location. From the 10th to the 18th the maximas were: 29.5°C, 26.5°C, 24.6°C, 25.9°C, 28.6°C, 25.9°C, 23.9°C, 29.8°C and 25.4°C. Although under high pressure for the 8 days it was rarely sunny, instead often cloudy and muggy apart from the first couple of days.

The final part of the month was once again cool and wet, with the maxima from the 19th onwards not rising above 21.4°C. The 26th also saw a minima of 9.5°C, the coldest recording of the month. The last 5 days of the month saw further rain, bringing the total to 68.0mm, making July the second month of 2005 with above average rainfall.

Sadly there were no thunderstorms this month, in fact it was pretty uneventful in that respect. However the month can be seen as a spectacular one due to the hot spell in the middle, which has even August 2003 beaten.
