Kish Island weather in May

Forum posters describe Kish Island's summer as genuinely the worst time to visit, with temperatures exceeding 40C and high humidity, some visitors specifically citing 110-115F conditions made worse by having to wear head coverings and coats. A local guide specifically advises against a September visit if it can be avoided, though notes conditions do moderate somewhat by the end of the month for anyone with no other option and reasonable heat tolerance. Posters consistently rate March-May and October-November as the genuinely comfortable windows, implying September sits at the tail end of the punishing summer stretch rather than truly in the shoulder season yet. Posters generally rate September as still hot and demanding for Kish Island, improving only toward the very end of the month, with October offering a clearly better-regarded alternative just weeks away.

Forum posters are direct that summer is the worst possible time to visit Kish Island, with temperatures reported well above 40C and stifling humidity, and consistently steer visitors instead toward the March-through-May and October-November windows as the genuinely pleasant times to go. Posters describe spring conditions warming steadily through the season, with April and May running noticeably hotter than March. Posters consistently recommend the warm, calm waters of the Persian Gulf here for swimming and water sports even outside peak summer heat. Posters generally rate March specifically as a comfortable entry point into that recommended spring window, before the fuller heat of April and May sets in.
