Let's face it folks, now it's it's really gonna rain!

Although being born an Englishman automatically qualifies one as an honorary meteorologist - we tend as a nation to greet our friends, neighbours and indeed, complete strangers, with our opinions of the current weather situation - no modern English weather-man has summed up the British climate in a single sentence better than the Roman historian Cornelius Tacitus, who in AD94 wrote:

'The sky is overcast with continual rain and cloud, but the cold is not severe.'
(Cornelius Tacitus, Agricola, 12.3.)

David Bowen has been collecting weather statistics over a number of years as a professional meteorologist for the Royal Navy. He recognised that certain trends in weather patterns occur at the same time every year. He published the following table from his compiled data, which shows the most likely weather sequences to be expected in Britain during any particular twelve month period.

The above table is reproduced verbatim from an article in Country Walking Magazine (April 1999, page 41); 'Beat The Weather', by David Bowen, a former naval meteorologist and weather forecaster, also the author of a number of books on the weather. I was impressed when I read his article and have noted that since publication, his forecasts have been remarkably accurate. See for yourself! Togodumnus - The RBO WebMaster
