Just wondering, with not much sign of any 'Summer' weather on the
horizon, how's the mean temperature for May doing? Any chance of May
being colder than this last April? Would be pretty unusual if it is...

Well, at the moment (1st - 16th) my averages a
Mean min: 7.7°C (+0.3°C)
Mean max: 16.3°C (+0.2°C)
Mean: 12.0°C (+0.2°C)

Treat my LTAs with a huge pinch of salt but it does look as if temperatures
so far for May are around or slightly above the 1971 - 2000 average.

As regards to being colder than this year's April then this is highly
unlikely as the average temperatures are above Aprils and I would expect
(though sometimes the reverse does happen) the second half of May to be
warmer than the first. Therefore, I would also expect this May and the
Spring as a whole to end up warmer than average.

April 2009 averages:
Mean min: 6.0°C
Mean max: 15.7°C
Mean: 10.8°C.

Spring 2009 (Up to 16th May)
Mean min: 5.4°C
Mean max: 14.8°C
Mean: 10.1°C

Out of interest, compare this May's to last year's May which was more like
June with regards to temperature.

May 2009 averages:
Mean min: 10.2°C
Mean max: 19.7°C
Mean 14.9°C.
