Tulum Weather: A Month-by-Month Climate Guide

Understanding Tulum's weather is key to planning a great trip — it affects everything from what to pack to which activities to prioritize and even how much you'll pay. Here's a month-by-month climate guide to Tulum, including the all-important topics of rain, hurricanes, and seaweed.

Tulum's climate in brief

Tulum has a tropical climate — warm to hot year-round, with a distinct dry season and wet season. Temperatures are consistently warm, generally ranging from the mid-70s to upper-80s Fahrenheit through the year, with high humidity. The two things that vary most are rainfall and, for beach lovers, seaweed. There's really no "cold" in Tulum; the question is how hot, how wet, and how crowded.

The dry season: November to April

This is Tulum's most pleasant weather and its high tourist season. Expect warm, sunny days, comfortable humidity, low rainfall, and calm, clear seas. Daytime temperatures sit in the pleasant high-70s to mid-80s, cooling slightly in the evenings. This is prime time for beaches, cenotes, and ruins — the weather is reliably lovely. The trade-off is peak crowds and prices, especially around Christmas, New Year, and Easter. If ideal weather is your priority, this is when to come.

The wet season: May to October

The wet season brings higher heat, higher humidity, and afternoon rain. Importantly, "wet season" in the tropics usually means short, intense downpours — often in the late afternoon — rather than all-day rain, so you can still enjoy plenty of sunshine. Temperatures climb into the upper-80s and feel hotter with the humidity. The upsides are far fewer crowds and significantly lower prices. If you can handle heat and the odd storm, the wet season offers great value.

Hurricane season

The Atlantic hurricane season runs from June through November, peaking around August to October. Tulum's Caribbean location means it can be affected, though direct hits are relatively uncommon in any given year. Most wet-season trips see nothing worse than heavy rain, but weather can be unpredictable in these months. If you travel during hurricane season, travel insurance and flexible bookings are especially wise, and it's worth monitoring forecasts as your trip approaches.

The seaweed (sargassum) factor

A uniquely Caribbean consideration is sargassum — brown seaweed that can wash onto beaches, typically peaking from around May to August, though it varies significantly year to year and beach to beach. In heavy periods it affects the pristine look of the sand and water, though hotels and beach clubs work to keep their areas clean. If a flawless beach is central to your trip, the dry-season months (roughly December to April) generally see the least seaweed. Always worth checking recent conditions for your specific dates.

Month-by-month summary

• December–February: Warm, dry, sunny; least seaweed; peak crowds and prices.
• March–April: Warm and dry; very busy with spring break and Easter.
• May: Hot, mostly dry early on; seaweed begins; good shoulder-season value.
• June–August: Hot, humid, afternoon rains; more seaweed; low prices.
• September–October: Wettest months, peak hurricane risk; quietest and cheapest.
• November: Rains easing, weather improving; excellent shoulder month.

The bottom line

What to expect day to day

On a typical Tulum day in any season, expect warm mornings that heat up through midday, with the strongest sun and heat in the early afternoon. In the wet season, clouds often build in the afternoon with a chance of a short, heavy downpour before clearing. Evenings are warm and pleasant year-round, ideal for open-air dining. Humidity is a constant companion, more noticeable in summer. Ocean breezes on the coast provide welcome relief. Planning strenuous activities like ruins visits for the cooler morning hours is always wise.

How weather affects your activities

Weather shapes the ideal Tulum itinerary. The strong midday sun makes late morning to early afternoon best spent in the shade, in a cenote's cool water, or at a beach club rather than hiking exposed ruins. Cenotes are a fantastic all-weather activity — the water stays refreshing regardless of air temperature, and cave cenotes even offer shelter from rain. Beach days are best on calm, clear dry-season days. If rain rolls in during the wet season, it's usually brief, so you can often wait it out over a long lunch and resume your plans.

For the best weather, visit in the dry season (November to April), accepting bigger crowds and prices. For value and space, the wet season delivers, with the trade-offs of heat, rain, seaweed, and hurricane risk. Pack for heat and sun year-round, add rain protection in the wet season, and always bring reef-safe sunscreen. For more on timing your trip, see our best time to visit Tulum guide.
