March 2013
March sunshine over Jacob's Ladder beach at a very low tide
Overall this was a wet, dull and very cold month though temperatures were generally average or slightly above until the 20th. Not as cold in the Otter Valley as places further north and east but it was still the coldest March since records started here in 2005.
