Naples and Campania weather forecast for Tuesday, September 22: Sunny and cloudy, but winds are increasing.

Tuesday, September 22, 2026, began with generally stable weather conditions in Naples. According to the updated forecast, the city will be partly cloudy, with large clearings throughout the day and no significant precipitation. Temperatures will remain pleasant, with highs around 27-28 degrees Celsius and lows between 19 and 20 degrees Celsius.

The most significant trend today, however, concerns the wind. Northeasterly currents, already present in the early hours, are expected to strengthen in the afternoon. In Naples, gusts could reach 40-50 km/h between late afternoon and evening, accompanied by a progressive increase in sea levels.

Campania, variable cloud cover

The rest of the region will experience patchy cloud cover, alternating with clear spells. Coastal areas and the northern plains may see scattered clouds for much of the day, while the southern plains are expected to see more sunny spells. Clouds alternating with clear spells will prevail in the Apennine areas, with clear spells likely to clear in the evening.

Widespread rain is not expected. However, cooler air infiltrations at high altitude may favor some isolated events, especially in the southern regions, while Campania is expected to remain largely unaffected by the most significant precipitation.

Temperatures slightly decreasing

The transition to more autumnal conditions is starting to be felt, especially during the night and early morning hours. Temperatures in Naples will remain mild, with highs around 28 degrees, while temperatures are expected to drop further in the coming days.

The regional weather forecast also confirms a phase characterized by northerly currents and progressively cooler temperatures compared to previous days. The Italian Air Force reports a general influx of cooler air masses this week in the areas affected by the northerly currents.

Wind and sea, be careful from the afternoon

Wind will therefore be the main factor to monitor. In Naples, the forecast calls for northeasterly winds, intensifying in the afternoon and evening hours. The sea, initially calm or choppy offshore, will tend to become rough inshore and very choppy offshore towards the end of the day.

Available forecasts also signal a wind alert level in Campania from 2:00 PM on Tuesday, September 22nd until the morning of Wednesday, September 23rd, with possible disruption to outdoor activities.

The outlook for the coming days

The improvement won't be entirely linear. On Wednesday, September 23rd, the weather is expected to remain mostly sunny in Naples, but with temperatures dropping slightly further. On Thursday, September 24th, more unstable conditions are possible, with the risk of thunderstorms in some areas of the region.
