February 2015
A Triassic sandstone sea stack between Ladram Bay and Sidmouth at a very low February Spring tide.

A rather benign month. A little drier and sunnier than normal with the mean temperature below normal due to high number of cold, frosty nights. No particularly warm/cold/rainy/windy days or nights. Snowless. This is the 6th consecutive snowless February with the last February snow falling on the 3rd February 2009.
