Is April a good time to visit Naples?

April is not the strongest month here: mild days and frequent rain. The best months for Naples on our scoring are July, August, June; months averaging 25°C or more: Jun, Jul, Aug, Sep.

Comfortable afternoons, cool evenings

The mild daytime temperatures suit walking around without planning everything around midday heat. A light layer is a sensible starting point, with something warmer for sitting outside or staying out late. The warmest days can reach 21.2°C or more, so lighter clothing may be comfortable during a warm afternoon. That does not make April a summer month: the coldest nights fall to 6.7°C or below. Pack trousers, a jumper and a jacket rather than relying on shorts and T-shirts. If outdoor evening meals are important to you, be ready to keep your jacket on or choose an indoor table.

Leave room for rain in your plans

Rain is the main compromise in April, so keep your plans flexible rather than making every day depend on being outdoors. About 11 rainy days makes a waterproof jacket and shoes that cope with wet pavements sensible packing choices. That figure does not mean those days are wet throughout, but it is enough to take the risk seriously. There is still useful sunshine, averaging about 6.1 hours within 13.1 hours of daylight. Use the brighter weather for longer walks and leave indoor time movable. April suits travellers who can adapt their plans better than those who need consistently dry weather.

A city break rather than a swimming holiday

The sea averages 15.4°C in April, which is cold rather than merely refreshing. If comfortable sea swimming is central to your holiday, this is not a good month to choose. Mild air can make time beside the water pleasant when it is dry, but it does not make the water warm. April makes more sense for a city stay where swimming is optional and you are happy to dress for changing conditions. If your priority is warmer holiday weather, June, July and August rate better overall. Choose April for mildness, accepting the rain risk and the need for evening layers.
