Best time to visit Naples

May is the best month in Naples, scoring 84 out of 100, with January the weakest at 53. The 31-point spread means timing is worth planning around without being decisive. 5 of the twelve months sit within ten points of the best, so there is more than one right answer.

August is the warmest month at 33.3 °C and January the coolest at 12.6 °C — a 20.7 °C spread across the year. Around 74 days a year top 30 °C, concentrated in August and the months either side.

There is a real wet season here. January, November and December carry the rain — up to 13 wet days in a month — while June to August drop as low as 5. That 8-day gap is the biggest single difference between a good month and a bad one in Naples, and it moves further than the temperature does.

The sea is comfortable for swimming in June to October — 26.7 °C at its warmest against 14.3 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 9.3 hours in winter to 15.1 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are May, October, April. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
