Traveller notes on Marseille in August
Other months in Marseille
Marseille's forum calls November genuinely unpredictable — some marvelously mild days near 16°C mixed with brutal, rain-hammered ones, especially in the back half of the month. Regulars flag the Mistral wind as the deciding factor: when it blows, the day turns bright and sunny but noticeably colder, and hiking the calanques is fine as long as there's no rain or Mistral that day.
Marseille's forum rates May as close to the best month of the year for the south of France generally — warm enough to be outside without summer's oppressive heat. Regulars' consistent advice: light layers, since the day heats up and cools down noticeably from morning to evening.
