Cancun weather in January 7.2/10 score Very good 23° average average temperatures 0 mm precipitation 10h 54m daylight duration In comparison to the other months, January is the coldest. However, at the lowest, the temperature may drop to 20°C (68°F). Typically, the days and nights are almost equally warm, with only a several-degree difference in the temperature. During the day, it gets hotter, but never scorching: the northern trade winds, so-called El Norte, moderate the heat. As it’s windy all day long, after sunset, the weather might become chilly. For night walks, it’s good to have a light sweater or a jacket. The drop in the temperature doesn’t affect the water, and it remains comfortable for swimming throughout winter. The only thing that may intervene with the plans for beach vacations is cloudiness. In January, the sky is not that clear, and the sun might hide for a few days, but the clouds rarely bring rain. Being generally dry and warm, January is a good time for visiting Cancún.

Cancun weather in February 7.2/10 score Very good 24° average average temperatures 0 mm precipitation 10h 55m daylight duration In February, the weather is almost identical to the conditions of January.

Occasional rain might burst in during the month, but it’s never prolonged and barely brings any inconveniences.

The temperature doesn’t rise too much and usually stays under the mark of 30°C (86°F). The days are pleasantly hot, but the breeze doesn’t let them turn sultry. Meanwhile, the majority of the time, it’s sunny, and the clouds rarely appear in the sky. In March, the driest month of the year together with April, rain is a rare guest, and you don’t expect to witness it more than once or twice during your stay. The sea temperature is around 26°C (79°F), giving you a reason to spend an entire day swimming and sunbathing.

Cancun weather in April 6.4/10 score Good 26° average average temperatures 0 mm precipitation 11h 52m daylight duration The first half of April is as pleasant as March. This time is ideal for a visit as the dry season is coming to an end, but the wet one hasn’t begun yet. A slight increase in the temperature marks the transition. However, the humidity remains relatively low and makes the heat bearable. When planning your stay in Cancún in April, take into account the temperature fluctuations. The days get hot, with the temperature rising over 32°C (90°F), and at night it drops to 23°C (73°F). For late evenings and nights, a light jacket won’t be odd. April is one of the driest spring months as the May thunderstorms are still ahead. By the end of the month, the first signs of the wet season come into sight. In late April, occasional rains may occur, but they come in light, brief showers. In the worst-case scenario, it might rain for several consecutive hours.

Cancun weather in May 5.5/10 score Acceptable 28° average average temperatures 0 mm precipitation 12h 29m daylight duration May is the official beginning of the rainy season. In Cancún, it lasts until October and brings higher temperatures and a noticeable increase in precipitation. However, the first weeks of May are the transition time, and the rains are somewhat rare. It is the mid-month when showers become more frequent and heavy, and you may expect a thunderstorm to intervene with your plans for sunbathing. Regardless of the rains, the weather is generally sunny: when a storm is over, the sky clears up quickly. Besides, the temperature rises and, at the hottest point, it reaches up to 34°C (93°F). Although the sea breeze moderates the heat a bit, it’s no longer the refreshing northern wind. Thus, staying outdoors at noon is not such a pleasant experience, and it’s better to plan activities for mornings or evenings.

Cancun weather in June 4.9/10 score Marginal 28° average average temperatures 0 mm precipitation 13h 02m daylight duration The weather in June is not entirely pleasant, and it’s the start of the hurricane season in Cancún. It’s hot and humid, with frequent, intense rains. Together with September and October, June is one of the wettest months: you may expect pouring rains every other day. However, when the storm is over, the weather improves and becomes suitable for outdoor activities like sightseeing or swimming. The heat is the only inconvenience. Compared to spring, the temperature rises, yet not significantly. High humidity makes the heat more perceptible and, at about noon, especially bothersome. The nights are almost as warm as days and barely refreshing. Together with September, June is the cloudiest month of the year. It is particularly noticeable in the morning. By the end of the month, the conditions refine, and the rains become rarer and less intense.

Cancun weather in July 4.8/10 score Marginal 28° average average temperatures 0 mm precipitation 13h 22m daylight duration During summer, the weather conditions hardly differ from month to month. Thus, July is as humid and sultry as June. The humidity of over 80% doesn’t let you forget about the heat, day and night, as there is almost no difference between temperatures throughout the day. In the afternoon, when the thermometer reaches over 31°C (88°F), staying outdoors is unpleasant and somewhat harmful. Due to the humidity, it might get harder to breathe. The only thing that saves the day is the breeze from the Caribbean Sea. In July, its water warms up to 29°C (84°F). In the morning, you can take your time to enjoy swimming and sunbathing. The first half of the day is usually sunny and dry. The weather deteriorates in the afternoon, closer to the evening, when it gets cloudy and rainy.

In the morning, the sky is clear, and the water is usually warm and calm. However, the second part of the day brings prolonged rains.

However, it may start raining any moment during the day or night, so carrying an umbrella or a raincoat is a good idea. Frequent, abrupt, yet light, the rains are not torrential, but they may last for several consecutive hours. You may also expect thunderstorms. Besides, September is a risky month: tropical storms and hurricanes might hit the shore of Cancún. The chances are low, but they should not be neglected. Such conditions make September one of the wettest and cloudiest months of the year: it rains almost every day, and the cloud coverage reaches 70%. Although the sea is hot at 29°C (84°F), generally, the weather is not favorable for a beach vacation.
