I've consulted Old Overall's Almanac (which has been in the family for 400 years), examined my crystal ball, checked the seaweed hanging outside my door and cast some chicken entrails.
I am now in a position to tell you that in May 2009 in the UK there will be some sunshine, some cloud, some rain, some wind and possibly some fog. There will be mild days and cool days. The 7th May will be particularly warm as it's my birthday and I always have my breakfast outside on the patio.
