Overall 2007 was a mixture of sunshine and rain. There was above-average sunshine on seven of the 12 months and the year had a total of 1,679 hours of sunshine, 141 hours above average.
By contrast eight months had above-average rainfall and the total of 842mm was 138mm more than usual.
One month, April, was out of the ordinary. It was by far the sunniest month of 2007 with 239 hours - that's more than 90 hours above average. It was also the driest with a barely-measurable 2.8mm of rain. However that was followed by the wettest month of the year, May, with nearly double the average rainfall and only two-thirds of the average sunshine.
