Comfortable daytime warmth, with cooler evenings

The daytime average of 19°C suits travellers who prefer being outdoors without strong heat. London averages 13.5°C in April, so Vilamoura offers a noticeable step up in warmth, though shorts and a T-shirt will not suit every part of the day. The warmer days can reach 22.8°C or more, but only 2% reach 25°C: do not plan around hot weather. A light top may be enough in a warm afternoon, while a jumper or jacket makes sense after sunset. Nights average 12°C, with the coldest dropping to 10°C or below, so pack for a cool walk back rather than a balmy evening.

Enough sunshine to enjoy, but leave room for rain

April brings about 6.9 hours of sunshine a day within 13.0 hours of daylight, giving you scope to enjoy time outside without assuming clear skies throughout. The catch is rain: about 7 days have measurable rainfall, so a completely dry stay is not something to count on. Keep outdoor plans flexible and bring a light waterproof rather than packing only for sunshine. The monthly averages do not tell you when rain will fall or how long a wet spell will last. This is a better fit for travellers happy to adjust their day than for anyone whose holiday depends on uninterrupted sun.

The sea is the main limitation

The sea averages 16.1°C in April, with a year-to-year range of 15°C to 17°C. That is cold water, even when the air feels pleasant, so a sunny afternoon should not be taken as a sign of comfortable swimming conditions. If you dislike cold water, treat the coast as somewhere to spend time beside rather than somewhere to linger in the sea. April makes more sense for a mild-weather break than a swimming-led holiday. June, July and August score better overall here, so they are worth considering instead if April's combination of cool water, mild air and some rain feels too much of a compromise.
