Gotland in October

April through June brings wildflowers, mild temperatures around 22°C, and empty beaches. The sea reaches 20°C by May — cold but swimmable. September and October offer the sweet spot with 25°C weather, warm seas at 23°C, and harvest season bringing fresh figs to market stalls. July and August mean 30°C heat, crowded ferries, and hotel prices doubling. But the festa season lights up villages with fireworks and street food every weekend. December through March sees temperatures drop to 15°C with frequent rain, though accommodation costs half the summer rates. Many restaurants close from January to March, leaving limited dining options.
