Hot days, with little cooling after dark

Cancun in April suits travellers who enjoy warmth from morning into the evening. Days reach 25°C on 98% of occasions, so cool daytime weather is not the usual concern. Only 6% reach 30°C, but humidity of 75% can make the heat feel more demanding than the temperature suggests. Keep more active plans for the cooler parts of the day and leave room for a shaded lunch or an indoor break. Pack loose, breathable clothing and light evening outfits: with an average night low of 24.4°C, you should not expect much relief from the heat after sunset.

Plenty of sunshine, but allow for rain

April offers about 7.7 hours of sunshine within 12.5 hours of daylight, giving you a useful amount of bright weather for time outdoors. There are about 7 rainy days, so it is better to allow some flexibility than to assume every day will stay dry. That does not mean those days are wet throughout, and the monthly figures cannot tell you when rain will arrive. Bring a light rain layer and keep some plans easy to rearrange. April is a good fit if you can accept occasional wet weather; it is less suitable if guaranteed sunshine is central to the trip.

Warm water makes swimming a strong reason to go

The sea averages 26.6°C in April, making swimming a clear reason to choose this month. The year-to-year range is 26°C to 27°C, so the water is consistently warm in the figures rather than hovering around a bracing temperature. For a holiday built around swimming and relaxed time by the water, that is a useful match with the hot afternoons. Sea temperature alone does not tell you about waves or local swimming conditions, so follow advice where you swim. Between swims, use shade and sun protection rather than treating time in the water as a break from sun exposure.
