Cancun in January: high season with perfect weather and clean beaches.
January in Cancun has a maximum temperature of 28°C, a minimum of 21°C, and sea water at 26°C. It is the peak season month: predominantly blue skies, rare rainfall (65mm), and beaches in excellent condition.
The nights are slightly cooler, making a light jacket necessary for al fresco dining. It's one of the most popular months for Brazilians during the summer holidays—which drives up hotel and tour prices. Book in advance.
Cancun in February: the driest month, ideal for those who want to escape the crowds.
February is the driest month in Cancun: only 40mm of rainfall, a maximum temperature of 29°C, a minimum of 21°C, and sea water at 26°C. It is considered by many to be the best month to visit the city.
The beaches are clean, the sea is crystal clear, and tourism hasn't yet reached its Spring Break peak. For those who want perfect weather with beaches less crowded than in March, February is the ideal choice. The first groups of American students begin arriving at the end of the month.
Cancun in March: clear skies and Spring Break — the busiest month of the year.
March in Cancun sees highs of 30°C, lows of 22°C, water temperatures of 26°C, and is the month with the lowest rainfall of the year (35mm). The weather is excellent, but Spring Break dominates the scene.
Starting in the second half of the month, university students from the United States flock to the beaches, hotels, and bars. If you're looking for excitement and parties, March is perfect. If you prefer tranquility, avoid the last two weeks of the month and the first two weeks of April. Prices rise considerably during this period.
Cancun in April: best value for money of the year after Spring Break
April has a maximum temperature of 31°C, a minimum of 23°C, sea water at 27°C and only 32mm of rain. It is the best value-for-money month in Cancun: excellent weather, more affordable prices after Spring Break and tourism declining.
From the second half of the month onwards, the beaches become noticeably quieter. Hotels and all-inclusive resorts offer much better rates than in March. Activities such as diving in Cozumel, excursions to the cenotes, and visits to Chichén Itzá have excellent weather conditions this month.
Cancun in May: empty beaches, low prices, and still excellent weather.
May registers a maximum temperature of 32°C, a minimum of 25°C, water at 28°C and rainfall of 75mm. The rains are starting to appear, but are still sparse and brief. It is the month with the lowest tourist flow of the year.
For those with flexible dates, May is one of the best options: the weather is still very good, the beaches are practically empty, and prices are low season. The perceived temperature is already more intense — hydration and SPF 50+ sunscreen are essential.
Cancun in June: beginning of summer, tropical rains and hurricane season.
June marks the beginning of summer and hurricane season. Maximum temperature of 33°C, minimum of 25°C, water at 29°C and rainfall of 135mm. The rains are tropical — quick and intense, usually in the late afternoon.
The sun shines for most of the day, allowing you to enjoy the beaches as usual. Prices drop significantly compared to the high season, making June an excellent option for those who want to save money. Pay attention to weather news and purchase travel insurance with coverage for weather events.
Cancun in July: school holidays, intense heat, and sargassum on the beaches.
July in Cancun has a high of 33°C, a low of 25°C, water temperatures of 29°C, and 95mm of rainfall. It is one of the hottest months of the year, with quick tropical rains and the presence of sargassum on the beaches.
Brazilian and American school holidays coincide, increasing activity at resorts. Beaches in the Hotel Zone may have sargassum seaweed, especially those further south. During this period, Isla Mujeres, Holbox, and Cozumel are options with less impact from algae. Water parks like Xcaret and Xel-Há are excellent choices for families.
Cancun in August: peak heat, high humidity, and best resort prices.
August registers a maximum temperature of 33°C, a minimum of 25°C, water at 29°C and 120mm of precipitation. It is the peak month for heat and humidity, with the possibility of tropical storms. Sargassum seaweed reaches its peak on the beaches.
Despite the intense heat, all-inclusive resorts offer low prices and complete facilities for those who don't want to leave the hotel. For excursions, opt for mornings when the heat is still more bearable. Monitor weather forecasts carefully.
Cancun in September: peak hurricane season and prices up to 50% cheaper.
September is the month with the highest rainfall (195mm) and the peak of hurricane season. Maximum temperature of 32°C, minimum of 24°C and sea water at 29°C. It is also the month with the lowest prices of the year — up to 50% discount compared to the high season.
Life in Cancun continues as normal, with hotels and restaurants operating regularly. The chances of witnessing a hurricane are low, but real. If you have complete flexibility and prioritize maximum savings, September might be worthwhile—provided you purchase good travel insurance and accept unpredictable weather conditions.
Cancun in October: end of hurricane season and gradual change in weather.
October is still rainy (189mm of precipitation), with a high of 31°C, a low of 23°C, and water at 28°C. It represents the end of the hurricane season and the beginning of climate recovery.
In the second half of October, the weather starts to noticeably improve. Prices are still low, tourist activity is reduced, and those who travel in the last week of the month generally find much better conditions. A good option for those who want to save money without facing the worst of the rainy season.
Cancun in November: the underrated month with great weather and affordable prices.
November marks a climatic turning point in Cancun: highs of 29°C, lows of 23°C, water at 27°C, and 98mm of rainfall. The weather improves week by week, and prices remain affordable.
It's considered one of the most underrated months to visit Cancun. The beaches become progressively cleaner, the sargassum disappears, tourist activity is low, and hotels offer excellent rates. In the second half of the month, the weather is already very close to the perfection of the high season, for a significantly lower price.
Cancun in December: Christmas and New Year's Eve in the Caribbean with spectacular weather.
December has a high of 28°C, a low of 22°C, water temperatures of 27°C, and 75mm of rainfall. It marks the beginning of the high season with the end-of-year festivities. The weather is excellent and the beaches are at their best.
Many Brazilians choose to spend Christmas and New Year's Eve in Cancun, which significantly raises prices in the second half of the month. If you plan to travel in December, book at least 3 months in advance. The nights are slightly cooler—bring a light jacket for evening strolls and beachfront dinners.

FAQ
Ideally, you should spend 7 days in Cancun to visit the main beaches and take excursions to Chichén Itzá, cenotes, and islands. With 7 days, you can fully enjoy the hotel zone, take 3-4 important tours, and still have time to relax at the resort. If you have less time, the minimum recommended stay is 5 days. With 10 days or more, you can include Tulum, Playa del Carmen, and explore more remote cenotes like Bacalar.
Sargassum season runs from April to August, peaking between May and July. Sargassum is a type of brown algae that washes up on the beaches, but Cancun is less affected than Tulum and Playa del Carmen. In my 15 years living here, I've observed that Cancun's beaches (especially Tortugas, Caracoles, and Langosta) suffer less from this problem. For real-time monitoring, follow the Quintana Roo Sargassum Monitoring Network on Facebook – they publish daily maps showing which beaches have algae.
Yes, you need an electronic visa that costs $10 per person for Brazilians visiting Cancun for up to 180 days as tourists. You also need a valid passport (with at least 6 months of validity), a return ticket, and proof of accommodation. At Mexican immigration, you will receive the FMM (Forma Migratoria Múltiple) free of charge – keep this paper safe as you need to return it when leaving the country.
The sea water temperature in Cancun varies very little: it stays between 26-29°C all year round. In the summer months (June-August) the water reaches 29°C, while in winter (December-February) it is around 26-27°C. It's always great for swimming! The temperature of the cenotes, on the other hand, is constant: 24-25°C throughout the year, perfect for cooling off from the heat.
Cancun is safe for tourists, especially in the hotel zone and tourist areas. In my 15 years living on the Riviera Maya, I have always advised visitors to follow basic precautions: do not walk alone at night in deserted areas, do not display valuables, use official taxis, and avoid downtown Cancun after dark. The hotel zone has 24-hour private security. Mexico has problems with violence in some regions, but Cancun is a government-protected area precisely because it is a tourist zone.
September is the cheapest month to go to Cancun (up to 70% off), but it's also the month with the highest risk of hurricanes and heavy rains. If you accept the calculated risk and have flexibility in your itinerary, it can be a great opportunity – our research shows that packages costing R$12.000 in January are available for R$4.200 in September. Purchase travel insurance that covers hurricane cancellations. In my 15 years here, I've only witnessed 2 hurricanes that truly impacted trips.
September is the rainiest month in Cancun, with an average rainfall of 230mm. October comes in second with 190mm. These are tropical rains that last 30-60 minutes (usually in the afternoon) and then the sun returns. The driest months are February (55mm), March (45mm) and April (40mm) – perfect for those who want guaranteed sunshine all day long.
No, December is outside of hurricane season in Cancun. The official hurricane season runs from June to November, peaking in August-September. December is one of the safest months of the year in terms of weather: dry weather, no hurricanes, no heavy rains. It's high season precisely for that reason – December offers the best weather conditions, especially for those who want to spend Christmas and New Year's in the Caribbean.
It depends on your preferences and the excursions you want to take. Cancun is better for those who want all-inclusive resorts, more developed beaches, a vibrant nightlife (Coco Bongo), and a nearby airport. Playa del Carmen is more alternative, intimate, with the famous Fifth Avenue for nighttime strolls and closer to Tulum and cenotes. My recommendation: stay 4-5 days in Cancun at an all-inclusive resort and 3-4 days in Playa del Carmen at a boutique hotel to experience the best of both worlds.
Travel insurance is not mandatory for Cancun, but it is highly recommended. In the US and Mexico, a simple medical consultation costs USD 200-500 and hospitalization can exceed USD 10.000. Insurance also covers cancellations due to hurricanes (important if traveling between June and November), lost luggage, and flight problems. Good insurance costs R$ 15-25 per day and can save you from enormous expenses – I've seen tourists paying USD 8.000 for appendicitis.
The best time to see sea turtles in Cancun is from May to September, when they arrive to lay their eggs on the beaches. The peak nesting season is between June and August. To swim with turtles, visit Akumal (1 hour from Cancun) where you can find them year-round feeding on seaweed in shallow waters. The best time is early morning (7-9 am) when there are fewer tourists and better visibility.
In Cancun, the official currency is the Mexican peso, but US dollars are widely accepted in hotels, restaurants, and tourist shops. Brazilian reais are NOT accepted. I recommend bringing US dollars and exchanging them for pesos at exchange bureaus in the hotel zone (better rates than at the airport). For small purchases, bars, and local markets, pesos are better. Credit cards work well, but have a 6,38% IOF tax – consider a card without IOF to save money.
Yes, Uber works in Cancun but in a limited way. The app operates in the hotel zone and downtown, however drivers cannot pick up passengers at airports and some hotels prohibit Uber from entering (resort lobbies). Alternatives: official taxis (more expensive but reliable), ADO for airport transfers (USD 12 per person) or renting a car. If you use Uber, ask to be met on a street near the hotel, never at the main entrance.
It's definitely worth it if you plan to relax at the resort and do few excursions outside the resort. All-inclusive resorts in Cancun offer excellent value for money: food, drinks, activities, and entertainment are included. For families and couples who want peace and quiet, it's perfect. But if you want to explore the region (cenotes, ruins, Tulum), consider splitting it: 3-4 days at an all-inclusive resort + 3-4 days at a regular hotel for excursions. This way you can enjoy the best of both worlds without being tied to the resort.
Cancun is a specific city with a 22km hotel zone. The Riviera Maya is the entire 130km coastal region stretching from Puerto Morelos to Tulum, including Playa del Carmen, Akumal, and other destinations. Cancun is geographically part of the Riviera Maya. When people say "I'm going to the Riviera Maya," they usually mean Playa del Carmen or Tulum, not Cancun. Cancun has its own airport and is more developed/touristy; the Riviera Maya is more rustic and alternative in some areas.
