It’s a gorgeous sunny day in March on the Ise of Tiree and the surf forecast gets 4 stars, so it’s time to hit The Maze for a bodysurf. The water temperature forecast reads “very cold (8 °C)”, and the air temperature is 6 degrees - about as cold as it gets here in winter due to the influence of the Gulf Stream. During February and March, the ocean mercury dips to its lowest level of the year and despite the warm sunshine, I need to consider how best to stay warm.
