Mazatlan, located on the Pacific coast of Mexico, boasts a predominantly tropical climate with warm weather year-round. The city is characterized by two main seasons: dry and wet, making it attractive to visit at different periods depending on your preferences.

The dry season usually lasts from November to May. During these months, you can expect many sunny days with minimal rainfall. Average temperatures range from a pleasant 21.5°C in January and February to a warmer 25.4°C in May. This is the ideal time for those seeking sunny weather and comfortable conditions for beach holidays and excursions.

The rainy season occurs from June to October. During this period, air temperatures reach their maximum values, averaging around 27-28°C, and sometimes exceeding 30°C. Rainfall increases noticeably, especially in July, August, and September, when the highest number of rainy days is observed. Despite the rain, showers are often short-lived and refreshing, after which the sun comes out again.

The temperature pattern in Mazatlan is distinguished by pleasant warmth throughout the year, although it has its seasonal nuances. The hottest months are traditionally July and August, when the average air temperature holds at around 28.5°C, and daily highs regularly exceed 30-31°C. January, February, and March are considered the coolest, with an average temperature of about 21.5-21.6°C. March records the lowest average minimum temperatures, dropping to 17.2°C, ensuring fresh mornings and evenings.

The summer period, spanning from June to October, is characterized in Mazatlan as hot and humid. Average daytime temperatures during this time range from 27.5°C in June to 28.6°C in July. Nights also remain very warm, with minimum temperatures rarely falling below 24.5°C (in June) and reaching 26.2°C (in July). The high humidity accompanying the rainy season intensifies the sensation of heat, making air-conditioned spaces particularly appealing.

The winter months, from December to March, offer guests of Mazatlan very comfortable weather. Daytime temperatures during this period are usually in the range of 25.6°C to 26.8°C, which is ideal for walking and relaxing on the beach. Nights become noticeably cooler, with average minimum values from 17.2°C to 18.5°C. A characteristic feature of the weather in Mazatlan, especially in the dry season (from November to April), is significant daily temperature fluctuations: the difference between daily highs and nightly lows can reach 8-9°C. In the summer, wetter months, this difference decreases to approximately 4-6°C, meaning a more consistent temperature throughout the day.

Mazatlan experiences distinct seasonality in precipitation, clearly dividing the year into a long dry period and a shorter but intense rainy season. Understanding these climatic features will help you optimally plan the timing of your trip.

The dry season in Mazatlan lasts from November to May. During these months, the probability of rain is minimal. The spring months are particularly arid: March, April, and May, when, according to statistical data, no precipitation falls at all (0 mm) and not a single rainy day is recorded. During the other months of the dry season – January, February, November, and December – there is also practically no rain, with total precipitation of no more than 1 mm and just one rainy day per month.

The rainy season covers the summer and early autumn months, from June to October. The highest amount of precipitation and rainy days falls in August, which is the wettest month of the year: an average of about 7 mm of precipitation falls, and the number of days with rain reaches 22. July and September are also characterized by high precipitation activity, with 15 and 20 rainy days respectively, and an average rainfall of 3 mm and 6 mm. Rains during this period are most often typical tropical downpours – they can be heavy but often short-lived, bringing relief from the daytime heat. June and October serve as transitional months: the number of rainy days in them (5 and 8 respectively) is already noticeably higher than in the dry season, although the total amount of precipitation remains relatively small (1-2 mm).

When packing for a trip to Mazatlan, it is important to consider its tropical climate with distinct dry and wet seasons. Year-round, you will need light, breathable clothing made from natural fabrics (cotton, linen), swimwear, sunglasses, a hat, and high-quality sunscreen with high SPF. Comfortable shoes for walking around the city and the beach are a mandatory attribute of your luggage.

If your trip falls during the dry season (from November to May), when rainfall is minimal and days are sunny and warm, focus mainly on a summer wardrobe: shorts, T-shirts, and sundresses. Evenings and early mornings, especially from December to March, can be slightly cooler (minimum temperatures drop to 17-18°C), so a light sweater, cardigan, or thin jacket will not be amiss. At this time of year, you will likely not need an umbrella.

During the rainy season (from June to October), the weather in Mazatlan becomes hot and humid, with frequent but usually short-lived downpours, especially in July, August, and September. During this period, be sure to bring a light raincoat or a compact umbrella. Clothing should be not only light but also quick-drying. Despite the rain, the temperature remains high, so warm clothes are unlikely to be useful. Don't forget insect repellent, as humidity promotes their activity. The principle of layering is less relevant here due to consistently high temperatures, but quick-drying clothes and rain protection take priority.
