cold front (area of low-pressure) in the middle of the month.

         What was exceptional was the number of sunshine hours
         measured. With 245 hours recorded this was the highest in our
         area since 1895, when measurements were first taken.
         Furthermore, the 30th was the sunniest April day ever recorded.
         There was not a single day when the sun did not shine. Note that
         the Ultraviolet Index (UVI) becomes high at this time of the year
         even though the days may feel cool. Protection from the sun

                                                   between the months of
                                                   April and September,
                                                   when the UVI regularly
                                                   exceeds three, as shown
         on the chart for sunshine and UVI levels.

         Where has the rain gone?

         We are currently experiencing one of the driest meteorological
         spring periods, ie March to May, since records began according to
         the Met Office [1]. As I write this article there are still two weeks
         until the start of meteorological summer on 1  June, so plenty of
                                                       st
         time for rainfall especially as school half-terms and a bank
         holiday approach! In the light of this announcement by the Met
         Office I looked up the rainfall data in Offchurch collected over the
         past 28 years, see chart below. If the rainfall for the remainder of
         May follows the current trend this will be our driest spring with just
         44 mm of rainfall from 1  March to 15  May. However, 2011 will
                                 st

         run this spring a close second at 52 mm and may still be the driest
         if we have more than 8 mm of precipitation in the next two weeks.
         Looking across the whole of the UK the rainfall for this spring
         needs to be under the 100.7 mm recorded in 1852, which is
