Naples weather by month
June is the best balance for warm days and swimming in Naples, while July and August suit travellers who want hotter, drier weather. For walking around the city, May and September are easier choices, with daytime averages of 22°C and 25°C. June reaches 26°C without the stronger midsummer heat. The main trade-off is rain outside summer, especially in late autumn, while winter needs layers rather than beachwear.

Spring: comfortable walking weather, but a cool sea
Spring becomes steadily more comfortable for spending the day outdoors. March averages 15°C by day and 7°C at night, so bring a jacket rather than relying on sunshine for warmth. April reaches 18°C, making walking more appealing, though both months average 11 rain days: keep plans flexible and carry a waterproof layer. May offers the clearest shift towards summer, with 22°C days, milder evenings and fewer wet days. It suits travellers who prefer exploring without midsummer heat. Swimming is the catch: the sea is only 19°C in May, so warm air does not yet mean comfortably warm water for everyone.
Summer: the strongest choice for sunshine and swimming
June brings warm conditions without quite reaching the heat of July and August. With the sea at 23°C and nights averaging 18°C, it is a sensible choice if swimming matters but you still want comfortable time on foot. July is the sunniest month, with 12 hours of sunshine, while August is hottest, averaging about 30°C by day. Both average just 4 rain days and sea temperatures of 26°C, making them the strongest choices for warm-water swimming. The catch is midday heat: plan longer walks for mornings, seek shade later and pack light clothing. Nights averaging 21°C offer limited cooling after hot days.
Autumn and winter: lingering sea warmth, then wetter days
September keeps much of summer's warmth, with 25°C days and a 24°C sea, but rain becomes more frequent. October remains pleasant for walking at 21°C, and its 22°C sea may still suit swimming when conditions are settled. November is the wettest month, so flexibility matters more than warmth: daytime averages of 17°C can feel inviting, but outdoor plans need a backup. December turns cooler at 13°C, followed by 12°C days in January and February. Winter nights call for a proper jacket, and regular rain makes waterproof footwear useful. January's sea is chilly and February's cooler still, so these months suit a city break rather than a swimming holiday. Expect to make the most of dry spells rather than plan every day outdoors.
