Where to go in June

Puerto Vallarta suits travellers who prefer hotter days and slightly cooler evenings: it reaches 31°C by day and falls to 24°C at night. Its 18 rainy days give it a small advantage over the other destinations, but not enough to call it a dry option. Cancun reaches 29°C, with 19 rainy days, making it a slightly cooler daytime choice. Riviera Maya, Playa del Carmen and Tulum have matching figures: 29°C days, 26°C nights and 20 rainy days. There is little weather-based reason to favour any of that group. Sea temperatures are 28°C throughout, so choosing between these destinations will not bring cooler or warmer water.

What the weather means for your plans

Plan for heat without assuming clear skies. Mexico's June average of 4.9 hours of sunshine leaves room for sunny spells, but frequent rainy days make a rigid outdoor schedule a poor fit. Keep plans easy to rearrange, pack a light waterproof and choose somewhere you would be comfortable spending time during rain. For hotter parts of the day, build in shade and breaks rather than packing your schedule. Light clothing is the practical starting point, and warm nights make cooling in your accommodation a useful priority. The sea is warm enough to appeal to travellers who dislike chilly water, though temperature alone does not tell you about swimming conditions.
