    A normal May mixture of good and bad with temperatures generally around average and unexceptional. The main feature of the month was very cool and wet late spring Bank Holiday weekend conditions on 27th/28th, which raised rainfall levels rather above average for the month. The 28th with a daytime max of 7.7 ºC was the coldest day for any date in May since recording began at this site (just beating May 17th, 1996 in the awfulness stakes).

    Well taking advantage of having to come home because My Mother had another turn I've slapped the figures on my website.

    One interesting thing I noticed the day time highs were the lowest since 1996 and continued the trend of recent Mays. Quite a reversal compaired to April.

    May 2007 Report.

    By Paul Carfoot.

    The first week in to May continued as April with high pressure in charge, the weather here in Burton was dry sunny and warm.

    On the 6th the high that had been with us for so long gave ground and allowed low pressure to approach the country from the Atlantic.

    The weather in Burton turned unsettled and very breezy at times, but despite several fronts crossing the area between the 6th and 8th, little rain was recorded, less than 1mm. This all changed though by the 9th as pressure deepened further, I recorded 7mm on the 9th, but this was only the start as the weather became very unsettled indeed, and the rain continued for the next 7 days in a row. The 13th was particularly wet with a total of 20mm being recorded over a 9-hour period.

    We had to wait until the 20th before high pressure eventually nudged up from the SW. The period from the 20th to the 24th was pleasantly warm with sunshine here, with the temperature peaking at 23.3c on the 23rd.

    On the 25th the pressure began to fall as the high sank back towards the Azores.

    By the 27th low pressure had taken fall control to the south of the country and with strong cold NE winds and continuous moderate rain the temperature only just made double figures at 10.4c here.

    The cool unsettled conditions continued until the 30th with rather low night minimums and ground frost.

    Finally the last day of the month was warmer as the cool winds from the North Sea were cut off, but still rather unsettled with short sharp heavy showers.

    Summary.

    In stark contrast to the settled and very dry April, a very unsettled and thoroughly wet month with 70mm more rain than April.

    Stats for May 2007

    Average maximum temperature = 16.6c

    Average minimum temperature = 7.6c

    Mean temperature = 12.1c + 0.8c above the CET average.

    Warmest day on the 23rd = 23.3c

    Coldest day on the 27th = 10.4c

    Warmest night on the 17th = 12.3c

    Coldest night on the 30th = +0.5c

    Ground Frosts = 3

    Air frost = 0

    Days of snow = 0

    Days of lying snow = 0

    Thunderstorms = 0

    Rainfall total = 79 mm

    Rain total this year = 226mm

    May Statistics all somewhat unreliable due to problems with sensor, as it had technical problems, as well as the movement of the Summer sun meaning it fell directly on the sensor. Consequently all temperature data for May may as well be ignored.

    Average Maximum Temperature: 18.5 [13 data sets missing]

    Average Mimum Temperature: 6.0 [9 data sets missing]

    Highest Indoor Temperature: 25.6 (3rd)

    Lowest Outdoor Temperature: 1.0 (30th)

    May Rainfall: 107mm

    A mild, wet and dull month. The average temperature was exactly the same as May 2006, though the rainfall was substantially lower (May 2006 saw 92.1mm). It was also notable for being the first May since I began recording to have no minima below 5°C all month.

    The first few days were dry, cool and cloudy as Northerly winds brought in cloud from the cold North Sea. It was then all change, as brighter and milder weather arrived from the south-west on the 5th. The 8th saw the end of a long dry spell. March 24th - May 8th (46 days) saw only 2.0mm of rain, the longest such dry spell since I began recording. The wettest day of the month was the 13th, which saw over 24 hours of rain and a total of 20.7mm.

    The second half of the month saw warmer and sunnier weather. The 22nd and 23rd reached 22.1°C and 23.3°C with the temperature during the night falling no lower than 14.5°C - a new record. There was then abrupt change, as a southerly tracking depression dragged in cool air from the North-east. The 27th saw the lowest reading, reaching only 10.5°C, making it the coldest day since at least 1997.

    Overall, another above average month, the 14th in a row and the 9th consecutive month with an anomaly of more than +1.0°C.

    Stats for Cleadon, Tyne & Wear

    Mean Max: 15.6 (+1.7)

    Mean Min: 8.3 (+1.6)

    Mean Temp: 11.9 (+1.7)

    Warmest: 21.1C (24th)

    Coldest: 4.5C (21st)

    The mean max was higher than in relatively inland Newton Aycliffe, so it's quite possible that my back garden might still give rise to slightly anomalous readings on sunny days, though less so than before I moved the Stevenson Screen and added appropriate insulation on the top. The lack of cold nights was remarkable, with the minimum of 4.5C being the highest lowest temp for May since 1999.

    Rainfall: 38mm

    Days of thunder: 2

    Days of hail: 1

    Days of sleet/snow: 0

    Fog: 0

    Gales: 0

    Overall a dull mild May, though surprisingly it ended up slightly drier than average. It started dry and cloudy with coastal stratocumulus, sunshine and showers (with a hailstorm on the 8th) during the second week, and then the third and fourth weeks were largely dull and unsettled. Thunder occurred early on the 27th, and there was also a distant rumble on the 31st.
