April has two halves in Cancún and Easter is the line, for prices and increasingly for seaweed.
Weather#
| Typical | |
|---|---|
| Days | ~31°C / 88°F, hot |
| Nights | ~22°C / 72°F |
| Rain | A few showers |
| Sea | ~27°C / 81°F |
| Sargassum | Often begins; heavy May–August |
The seaweed, honestly#
Sargassum drifts onto east-facing Caribbean beaches from roughly April to August. Cancún's hotel zone has two faces: the long east-facing beach from Punta Cancún south catches it; the north-facing stretch near Punta Cancún and the lagoon side often don't. Isla Mujeres' Playa Norte and Holbox usually stay clear. Big resorts rake every morning. The sargassum guide explains the science for the whole Caribbean; Cancún vs Tulum vs Playa which coast does best.
Semana Santa#
When Easter is in April (2026: Holy Week 29 March to 5 April), the coast is Mexico's holiday: full beaches, full resorts, busy roads, a festive crowd. Book early or come the week after.
Prices#
High until Easter, shoulder after. Cancún on a budget.
What to do#
Mornings for the ruins and cenotes before the heat (day trips), Isla Mujeres on a clear-water day, the pool in the afternoon. Things to do, the 5-day itinerary, with kids.
Pack#
Light clothes, reef-safe sunscreen, water shoes if seaweed is in, a light rain layer. First time in Cancún.
Ask someone there#
Which beach was clear this morning: post your dates on Roavi Community and Local Friends who live in Cancún answer with photos, not brochures. One evening with one is downtown's food and music, far from the sand.
