Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at San Miguel de Cozumel: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest from December to March; quietest in April, May, June, August and September.

Then and now

Cozumel's April days now average 29.8°C, 2.9°C warmer than in 1981–1990. 12 of 12 months are clearly warmer.

Getting there

How far Cozumel is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type A and B plugs at 127 V. Drives on the right. The currency is the Peso. UK Foreign Office: avoid all but essential travel to parts. Everything for Mexico: cost of living, languages, emergency numbers and health.

Being there

On arrival

Paying — Cards are widely accepted in cities, in chains and bigger restaurants; carry pesos for markets, street food, small family-run shops and anywhere rural.
UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Tipping — 10-15% in restaurants, usually left in cash on the table; taxi drivers do not expect a tip.

Getting around Cozumel

Apps — Rides: DiDi, inDrive, Uber. Maps: Google Maps, Apple Maps. Messages: WhatsApp. Ride apps are not authorised to pick up at Mexican airports; at Mexico City airport, take a fixed-fare authorised taxi from the stands inside.

Walk, rent a car, or take a taxi; there is no public transit out of town. The docks are saturated by pushy touts trying to lure you into car rentals and activities. More on Wikivoyage
