I don't about Penzance but these last few days of warmth have pushed my mean
temperature for this January above last year's January:

Mean Min Mean Max Mean
Jan 2008 5.5C 10.2C 7.8C (1st - 24th)
Jan 2007 4.2C 11.0C 7.6C

The run of warm nights recently has pushed up the mean minimum quite
considerably after what was a cold start to the month with a couple of air
frosts.

With some calmer weather forecast, and my valley location the mean
temperature will probably drop back a bit.
