Hot days, with little cooling after dark

Average highs of 29.4°C sound manageable, but humidity of 85% makes this a less comfortable choice if you dislike sticky heat. Days reaching 30°C account for 25% of the month, so allow for hotter spells rather than packing only for the average. Keep outdoor plans gentle around midday, wear loose, lightweight clothing and make room for breaks in the shade. Nights average 25.4°C, so evenings offer limited relief rather than a proper cool-down. Prioritise accommodation where you can sleep comfortably in the heat. This weather suits travellers who enjoy warmth throughout the day and evening more than those who prefer fresh nights.

Plan around rain, not uninterrupted sunshine

With about 27 rainy days, wet weather needs to be part of your plans rather than treated as an unlikely interruption. That does not establish how long each spell lasts, so neither an all-day washout nor a quick shower should be assumed. Sunshine averages about 3.5 hours within 12.1 hours of daylight: there is time to be outside, but bright conditions are far from assured. Pack a lightweight waterproof and keep your daily schedule easy to change. April is a reasonable choice if warmth matters more than blue skies and you can accept time under cover. If rain would spoil the holiday for you, this is a difficult month to recommend.
