My recent fourth visit to Cuba (22-29 February) turned out to be the hottest trip to the Caribbean island yet.
Normal late February temperatures in Varadero range from a high of 26 C to a low of 16 C.
However during the week I visited, daily highs were at least 30 C with an average low of 17 C.
Even the locals were complaining of the heat since an average high of 30 C is more typical of May.
