    Average max = 18.28c (highest = 26.4c on 29th)

    Average min = 8.01c (lowest = 2.4c on 10th)

    Mean = 13.14c

    Weather report for May 2009 at Lampeter, Ceredigion

    Summary: Rather mild, rather wet.

    Although overall May 2009 had above average rainfall, some 86mm of the total fell in only one week, the 14th-20th. Likewise, regarding temperatures, although a fairly mild month overall, proper warmth (>21c), was delayed until the final 3 days of the month.

    1st -9th: Sunny spells but also some rain/ showers at times (small amounts). Temperatures early in the month varied between rather cool and rather warm, with a couple of ground frosts.

    10-12th: Sunny and rather warm, but windy at times.

    13th-22nd: Very unsettled and windy at times. There was plenty of heavy rain/ showers, and it was often cloudy and cool.

    23rd-25th: Mainly dry with sunny spells, rather warm.

    26th: Dry and cloudy.

    27th: wet and windy.

    28th-31st: It became very warm and sunny- at last! The final 3 days all reached 24c!

    The whole month was notable for a lack of cold, there being no air frosts, and the lowest maxima was a mere 11.6c.

    The warmest May since 1999 and the second warmest on record. Like March and April, it was well above average mainly due to the warm nights. Cold nights were completely absent. Daytime temperatures were unremarkable however. It took until the 28th to surpass 20°C - the latest date in the year to do so since 1988.

    The month started very mild but with frequent rainfall. It was also rather windy aswell, topping 20mph on all but one of the first 20 days. It then turned much cooler in the second week, with 6 days failing to record a maximum temperature of 15°C. It was also much wetter, with every day from the 13th-21st recieving more than 3mm of rain. The wettest was the 15th, with 12.4mm in the 24 hour period. It then turned very pleasant from the 23rd. Aside from three further days with small amounts of rainfall, it was mostly dry, sunny and warm, unusual as the wind was north-easterly.

    Overall, a very warm but pretty forgettable May. It meant that spring as a whole averaged 10.2°C - some 1.6°C above average, making it the second warmest on record just behind 2007. It also had all three months more than 1°C above the mean - the only other time this has happened is 2003.

    A bit late, but the data is in for Cleadon, Tyne & Wear, for May. All averages are estimated for 1971-2000.

    Mean Max 15.8C (+1.9)

    Mean Min 8.1C (+1.5)

    Mean Temp 11.9C (+1.7)

    Warmest Day : 21.4C (24th)

    Coldest Day: 12.1C (15th)

    Warmest Night: 12.1C (28th)

    Coldest Night: 3.0C (11th)

    Precipitation: 36mm (68%)

    Wettest day: 7mm (15th)

    There were no days with thunder, sleet/snow or fog, but hail was observed on 2 days- the 21st and 26th.

    Like at Reef's location this was a surprisingly warm May- about the same as last year, but with a higher average maximum and lower average minimum. Indeed, the average maximum was beaten only in 2001 and 2004 in a record going back to 1993. The warmth was due to the last third of the month, with persistently near-average temperatures during the first two-thirds but a notable absence of very cold days or nights.

    The first half was quite dry but often cloudy, the third week was unsettled and generally showery, but predominantly warm, sunny weather during the last third of the month led to sunshine across the region being rather above average.

    Spring 2009 as a whole was the equal second warmest on record (alongside 2003 but behind 2007), and it was the second driest on record after 2007 with only 76mm, barely half the long-term average.

    In the meantime, the average maximum for 1-15 June 2009 has come in at 15.7C.
