The station is Cancún, clave 23155, in Benito Juárez, 9 metres above the sea. It is the coast, not Mérida and not the inland peninsula. The National Hurricane Center's Atlantic season, 1 June through 30 November, covers the wetter half of the year on this shore.

The normal stays hot in every month. What changes is the rain. Use the strip to see the drier months and the heavy ones, and treat a monthly total as an average, not a promise about a particular week. The entry link is the immigration institute's page. This sheet does not rewrite it.

Driving side

Article 109 of the federal highway regulation, as published in the Diario Oficial on 22 November 2012, says vehicles are to be driven in the right-hand lane of a federal highway, except when overtaking, when the road is too narrow for two lanes, when the right side is blocked, on the three-lane case the article describes, or on a one-way road. This is the federal highway rule, not a city bylaw.

Tap water

CDC's traveler page for Mexico, last reviewed 3 September 2026, does not say whether tap water is safe or unsafe. It says food and water standards vary by destination and by what you are doing, and it points readers to CDC's food and water precautions. This page does not turn that into medical advice.
