Cancún: practical tips
1 h route3 stopsBest: Read before booking: half of this affects your datesUpdated July 2026
Cancún is an easy destination (you drink bottled water, card works nearly everywhere and English is spoken across the Hotel Zone) so the tips that matter aren’t about survival but about the calendar and your money.
Two of them you should read before buying the ticket, because they directly change which month suits you.

3 STOPS- 01
Sargassum and hurricane season
Sargassum, a brown seaweed, arrives in bulk in the Caribbean mainly between May and October. It isn’t dangerous, but it heaps up on the shore, smells of rotten eggs as it decomposes and turns the water brown. It varies enormously by day and by beach, so nothing can be guaranteed. What is true is that from December to April it rarely shows.
Atlantic hurricane season officially runs June to November, peaking August to October. Being hit is unlikely, but September is both the riskiest month and the cheapest, and those two facts are related.
If you travel then, insurance with cancellation stops being an extra and becomes the sensible move.

Money: pesos, tipping and the exchange trap
In the Hotel Zone many places price in dollars and take cards happily. Two warnings: their exchange rate is worse than your bank’s, and when the card machine asks whether you want to pay in your own currency, say no. That’s dynamic currency conversion and you always lose.
Pay in pesos, every time.
Tipping is firmly expected here, around ten to fifteen per cent in restaurants. Check the bill first: in tourist areas it’s common for a "suggested tip" to be included already, and if you don’t look you pay it twice.

Connectivity and the tropical sun
In Cancún, the Riviera Maya and along the main roads mobile coverage is good, and with an eSIM you land connected: which here buys you something concrete. Arranging transport, showing your booking, and checking the sargassum report for your beach before crossing the city.
Inland, around the cenotes and on stretches of the road to Chichén Itzá, there are dead zones: download the maps before you set off.
And the sun: you’re at twenty-one degrees of latitude and the UV index is extreme at midday even under cloud. Sunscreen also carries a local consideration: cenotes and reef parks require you to go in without it, or with a biodegradable one, because in a closed system the filter stays in the water and kills coral.
Frequently asked
Can you drink the tap water in Cancún?
Not advisable. Drink bottled or filtered water, which is what locals do too. Hotels and restaurants serve purified water and ice in established places is made with it.
When is the best time to visit Cancún?
December to April: outside hurricane season, with little or no sargassum and lower humidity. It’s also the priciest and busiest. November and early December tend to be the best balance of weather, price and crowds.
