Weather in Positano in July

Prime time. If you get to pick your dates, July is the one. Highs average 26.2 °C, lows 24.3 °C, and rain falls on 5 days — nothing in the month is working against you.

July is the highest-scoring month of the twelve. The nearest rival is August, and the month at the other end of the year is January.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average July reaches 30 °C; the day barely swings — 2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 31 °C and the coldest night fell to 20.8 °C, and the wettest single day dropped 26 mm — roughly 124% of the month's rain in one day.

July is moderately variable: 1 mm in the driest year against 65 mm in the wettest, around an average of 21 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 10.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

How July sits in the year

Temperatures hold steady either side: 23.6 °C in June, 26.2 here, 26.8 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Positano's year: 14.8 hours of daylight, losing 0.6 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 26 °C in July — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, October is the trade worth considering — 13 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Positano versus nearby

If Positano is one option among several, the nearby comparison is worth making. Naples is the weaker option in July — 6.8 °C warmer, the same number of rain days. Bari is the weaker option in July — 5.9 °C warmer, 1 day less rain.

So: July is the answer for Positano. If it is booked out or priced out, August is the next best thing at 0 points behind, and January is the month to keep off the shortlist.
