May is still a transitional month between our dry and rainy season. By late May the normal rainy season weather patterns are set - sunny mornings and rainy afternoons. But there will still be plenty of beach weather around the North Pacific coast. The rain begins earlier on the Caribbean side, with afternoon and overnight showers.
