Warm enough for light clothes, rarely hot

Sal's average daytime high is 8.7°C above London's April figure, so the change should feel substantial without being overpowering. Only 7% of days reach 25°C, making April better suited to travellers who dislike intense heat than those chasing it. Light clothes are a sensible starting point, with a light layer if you tend to feel cool while sitting outside in the evening. Average night temperatures stay close to daytime highs, so there is little typical overnight cooling. You need not plan around extreme midday heat, although comfort in direct sunshine will differ from the air temperature.

Very little rain, but not sunshine all day

Rain is unlikely to be the main compromise: April has about 0 rainy days, so outdoor plans have little typical rainfall to work around. That is not a promise of uninterrupted clear skies. There are about 6.7 hours of sunshine within 12.4 hours of daylight, leaving plenty of daylight that is not counted as sunshine. Keep your plans flexible rather than expecting every afternoon to look the same. Humidity averages 79%, so the air may feel more humid than the modest temperatures suggest. Breathable clothing makes sense, along with sun protection for time outdoors, even when the heat feels gentle.

Swimming is reasonable, but expect a fresh first dip

The sea averages 22.2°C, which puts April on the swimming side of the line rather than the bracing side. Still, this is not bath-warm water, and travellers who feel the cold may prefer shorter dips to long sessions afloat. The year-to-year range is 21°C to 23°C, so your experience could be fresher or warmer than the average suggests. April therefore suits a mix of swimming, sitting outside and taking breaks from the sun, rather than a holiday built entirely around prolonged time in the water. If very warm sea conditions are essential, the April figures leave room for disappointment.
