Weather in Merida

Planning your day in Merida? In this section, you will find the latest weather information, including up-to-date data, forecasts, and useful charts to make your stay in the city as comfortable as possible.

The climate in Merida can be described as tropical, with consistently high temperatures throughout the year. There are no cold winters here, and the annual average temperatures make the city attractive for those who love warmth. Travellers should be prepared for hot weather, especially during the spring and summer months.

Two main seasons are clearly distinguishable in Merida: the dry season and the rainy season. The dry season usually lasts from November to May. During this period, especially from February to April, rainfall is minimal, and there are very many sunny days. Temperatures are high at this time, reaching a peak in April and May, when maximum values can rise to 35-36°C. The rainy season covers the months from June to October. During this time, the number of days with precipitation increases (up to 17-21 days per month), although the total monthly rainfall remains relatively small (3-5 mm). This means that rains are likely to be frequent but short-lived, bringing freshness.

Thus, the weather in Merida is distinguished by stable heat all year round. The hottest month is May. If you prefer to minimise the chance of rain, the best time to travel is from late autumn to mid-spring. The summer months, despite a higher probability of precipitation, are also suitable for a visit, as the rains are often brief and help make the daytime heat more bearable.

The temperature regime in Merida is characterised by stable warmth throughout the year, without the sharp fluctuations typical of a continental climate. The annual range of average temperatures is relatively small. The hottest month is traditionally May, when the average air temperature is 30.4°C, and daytime maximums often reach 36.0°C. The "coolest" period is considered to be January, with an average temperature of 24.0°C. At this time, night-time temperatures can drop to 19.6°C, while during the day the air warms up to a comfortable 28.4°C.

The summer months in Merida, covering the period from June to August, are distinguished by persistent heat. Average daytime temperatures fluctuate within the range of 29.1°C - 29.4°C, while maximum values can reach 33-34°C. Considering that this is also a time of high humidity and frequent, albeit short, rains, the summer weather feels hot and humid. The "winter" months, from December to February, bring milder and more comfortable weather. Daily average temperatures during this period are 24.0°C - 25.6°C, with daytime highs around 28-30°C and night-time lows in the region of 19-20°C, which creates pleasant conditions for walking and exploring.

One of the characteristic features of Merida's climate is the noticeable diurnal temperature fluctuations. The difference between maximum daytime and minimum night-time temperatures can be quite significant, especially in the period from March to May. In these months, when the daytime heat reaches its peak (33-36°C), night-time temperatures drop to 21-25°C, providing a difference of 10-12 degrees. In other months, this difference is also palpable and averages 8-10 degrees. This means that even after a very hot day, the evening and night bring noticeable coolness, which is worth considering when planning your wardrobe for the trip.

Precipitation in Merida has a distinct seasonal character, divided into a dry period and a rainy season. It is important to note that even in the wettest months, the total amount of rainfall remains comparatively small, which is typical for a tropical climate with frequent but short-lived downpours.

The dry season in Merida usually lasts from November to May. The driest months are February and March, when, according to average data, no precipitation falls at all (0 mm), and the number of rainy days is minimal – just 2-3 per month. In January, April, November, and December, a very small amount of precipitation is also observed, around 1 mm per month, while there may be between 4 (in April) to 10 (in November) rainy days, indicating rare and, as a rule, very light rains.

The rainy season in Merida falls on the period from June to October. During this time, the frequency of precipitation increases significantly. Thus, August is the month with the highest number of rainy days – on average 21 days, followed by September (20 days) and June with October (17 days each). At the same time, the peak in rainfall volume occurs in June, when 5 mm falls. In the remaining months of the rainy season (July, August, September, October), the amount of precipitation fluctuates around 3-4 mm. Such a combination of a large number of "wet" days with a relatively small total volume of precipitation confirms that rains in Merida in summer and early autumn, though frequent, usually present themselves as short showers. Snowfall is not characteristic of Merida due to its tropical climate.

When planning a trip to Merida, it is important to consider its tropical climate with high temperatures year-round. The basis of your wardrobe should be light, breathable fabrics, such as cotton or linen. Regardless of the season, be sure to take sunscreen with a high SPF, sunglasses, and a hat for protection against the active sun. Comfortable walking shoes are another must-have, as you will surely want to explore the city's numerous attractions on foot.

Although there is no clearly defined winter in Merida, two main periods can be distinguished: the dry season (approximately from November to May) and the rainy season (from June to October). In the dry season, especially from February to April when precipitation is minimal, rely on summer clothes: shorts, t-shirts, sundresses. In the rainy season, which is characterised by frequent but usually short downpours (especially in August and September, when the number of rainy days reaches 20-21), a light raincoat or a small folding umbrella will not be amiss. Despite the rain, the temperature remains high, so clothing should still be light. In the evenings, especially during the period from December to February when night-time temperatures can drop to 19-20°C, a light cardigan or wrap may come in handy.

Given the consistently hot weather during the day and possible evening coolness, the principle of layering can be useful. For example, a light long-sleeved shirt will not only protect against the sun during the day but also keep you warm in the evening. Do not forget insect repellent, especially if you plan walks in the evening or visits to nature parks. An adapter for electrical appliances and a portable charger may also prove to be useful companions on your journey through Merida.
