June marks the official start of the rainy season across most of Mexico, but this doesn’t mean what people often assume. Rain typically falls in heavy afternoon showers (1–3 hours), not all-day downpours. Mornings are usually clear. June is one of the lowest-tourist months of the year, with genuine low-season prices.

How the rainy season actually works

In Mexico’s lowland areas (Caribbean coast, Pacific coast), rain falls mainly in the afternoon (2–6 pm) in concentrated showers. Mornings are clear and hot. You can structure your day to work with this — beach and outdoor activities in the morning, indoor/shade activities in the afternoon.

In highland areas (Mexico City, Oaxaca, San Cristóbal), the rain pattern is similar: afternoon showers that clear by early evening.

The rainy season is not the same as hurricane season. Early June sees some tropical storm activity but the peak hurricane risk is August–October.

What’s good in June

Whale sharks: June–September is the best period for whale shark encounters off Holbox and the Yucatán north coast. The aggregation grows through June. Far fewer tour boats than July–August.

Sea turtle nesting: Olive Ridley turtles begin nesting on Pacific coast beaches in June. Leatherback and green turtles nest on Caribbean beaches. Volunteer programmes in Oaxacan coast towns (Mazunte, Escobilla) welcome participants.

Cenotes: June’s heat makes cenote swimming very appealing; the tourist crowds are lower than July–August.

Oaxacan coast (Puerto Escondido, Huatulco): surf is building, turtle season is starting, the town has breathing room.

Weather by region

Yucatán / Caribbean: 31–34°C, increasingly humid, afternoon showers. Morning beach time is excellent.

Pacific coast: 28–32°C, rainy season beginning. Puerto Vallarta and Sayulita see regular afternoon rain from June.

Mexico City: 20–25°C, afternoon rain, pleasant mornings. A good month for the city.

Oaxaca City: 24–27°C, some afternoon rain. Good for exploring with fewer tourists.

Hurricane season note

The Atlantic/Gulf hurricane season officially begins 1 June. Statistically, June has very low hurricane activity — the significant risk months are August–October. Travel insurance with hurricane coverage is advisable for Caribbean coast bookings from June onwards.
