Hot days, warm nights and an inviting sea

The heat is dependable, but comfort takes a little planning. Humidity averages 81%, so the warmth can feel sticky, particularly when you are active. Keep clothing light and breathable, take breaks from the midday heat and choose accommodation where you can cool down comfortably. Average night lows are around 25°C, so evenings offer little relief rather than the cool finish you might expect in April at home. The sea averages 28.8°C, making swimming appealing if you dislike a chilly entry, although it will not feel especially cooling. This month suits travellers who enjoy sustained warmth more than those who want comfortable weather for being active throughout the day.

Plan around rain, not a fixed outdoor schedule

With about 23 rainy days, wet weather needs to be part of the plan rather than treated as an unlikely interruption. That does not tell you how long rain will last on any particular day, so neither a complete washout nor a brief shower should be assumed. Keep outdoor plans movable, pack a light waterproof and protect anything you carry that needs to stay dry. Sunshine averages about 4.1 hours a day, leaving scope for brighter spells without promising long sunny stretches. April makes more sense if you can enjoy downtime when conditions turn wet. If your holiday depends on uninterrupted time outside, the rain is a substantial drawback.
