According to the BBC, the next three days we will see a lot of rain, with the temperature remaining around the 12 - 13 degree mark. The weather is likely to remain rainy until Monday and Tuesday which we may finally get some sun in. As soon as Wednesday comes round it looks like even more rain for us.
Anyway rant over
The benefit to this is of course if you're growing certain plants as the rain is beneficial for them and lets hope we see some more nice weather in Surrey soon.
