Bob Farrer’s comments

36 mm of rain fell on Dudswell in March. This relatively low figure allowed some of the flooded fields to drain from large lakes to isolated ponds. The last week of the month brought a wonderful spell of weather with the highest March temperature (23 C) for over 50 years.

Kind regards
