    Temperature wise, a month of two halves, the first half of the month seeing maximum temperatures above 20ºC most days, also with exceptionally warm nights, temperatures rarely dipping below 15ºC during most nights. The average minimum temperature of 13.2ºC was considerably warmer than the 1971-2000 Durham average of 10.6ºC.

    Because of this, the mean temperature was pushed up to 16.4ºC, which is 1.3ºC above the 1971-2000 Durham average. The second half of the month was noticeably cooler and fresher. The warmest temperature recorded was just 26.0ºC (78.8ºF) on the 8th. We also had a record high night time minimum, where the temperature fell no lower than 18.3ºC (64.9ºF) in the 24 hours up to 9 am on the 9th August. The coldest temperature recorded was 7.2ºC (45.0ºF) in the early hours of August 22nd.

    The weather was very unsettled throughout the month with several bands of persistent heavy rain passing through the area. The month was also duller than average according to other local stations.

    One thing August 2004 will be remembered for is the incredible amount of rain that fell. This was not just the wettest August recorded in North East England, but several locations recorded their wettest month EVER. The rainfall total for Newton Aycliffe was a staggering 210mm!! That’s by far and away a rainfall record for this location.

    Compare the reading of 210mm this month to the 30 year Durham average of 61.3mm and it gives you an idea of just how wet this month was. Rainfall above 1mm was recorded on 15 days, compared to the 9.2 days that you might expect. The daily rainfall record was broken with 45mm recorded between 9am August 9th and 9am August 10th. A further 27mm was recorded in the following 12 hours, giving a 36 hour rainfall total of 72mm. The month was also unusually humid, with an average 9am humidity reading of 91.4%

    To summarise, a warmer than average month, although that was exclusively down to warm nights rather than warm days, which was dull, unsettled, incredibly wet, and humid.

    Hello

    My figures for just south of Doncaster are:-

    Mean Max 22.4C with an Absolute Max of 30.6C on 8th August

    Mean Min 14.0C with the lowest being on 21st August with an overnight Min of 8.8C

    The lowest daytime Max was 14.1C on 20th August.

    This gives a mean temp of 18.2C, 2.1C above the long term average for this area.

    I don't have any rainfall amounts, just the days with rain, I had 22, the long term average is 13.

    there were 3 days with fog reported(average1) and 4 days, possibly more with thunder(I'm deaf!!), long term average is 2

    All in all a warm but wet month.

    Tyneside's month was similar to what was described at Durham.

    However, it probably wasn't quite as wet, for many of the areas of heavy rain that affected Durham had weakened by the time they reached the coast- we ended up with more than our fair share of coastal drizzle.

    Due to the dominance of sea fog during the first half of the month, it is likely that South Tyneside was even more anomalously dull than Durham.
