Saint-Tropez has a classic hot-summer Mediterranean climate (Koppen Csa), with mild, relatively wet winters and long, hot, dry summers. The town’s position on the Gulf of Saint-Tropez moderates extreme temperatures, keeping summer highs around 29°C (84°F) rather than the 35°C+ seen inland in Provence. The Mistral wind occasionally sweeps through in winter and spring, clearing clouds but bringing chilly gusts. Sea temperatures peak at 24°C (75°F) in August, comfortable for swimming from June through late September. Here’s a month-by-month breakdown of what to expect.
