An important aspect when planning a trip to Cuba is to determine when to travel and for that it is important to know how the weather works, and because of the little and poor information I have found on the net, I have decided to do an article where I describe the behavior of the climate in each month as well as the climate in some of the most important tourist destinations of the island.
The weather in Cuba is warm tropical type, with rainy season in the summer. In general it is quite accepted to express that the climate of Cuba is tropical, with average temperatures of 25 ºC and sun almost all the year. The humidity is between 75% and 95% generally so it is convenient to always have a raincoat on hand to protect against any downpour.
The weather in Cuba is divided into two distinct seasons. The dry season from November to April, which is less humid and somewhat cooler, with an average of high temperatures between 21 and 28 ºC and an average of low temperatures of between 18 and 24 ºC; While the rainy season extends from May to October and the average temperature oscillates around 30ºC, with a slightly higher humidity. The hurricane season in Cuba begins on June 1 until November 30; While most storms occur mainly between the months of September and October.
January presents typical conditions of the winter, with the predominance of high continental pressures on our geographical area.It is one of the coldest months of the year, so it is usual to register remarkable minimum temperatures.The moisture content is the lowest of the year, and on ave rage, ra infall totals of 64.5 mm and a frequency of 6 days with rain are reported.
In February, the characteristics typical of the winter season are usually manifested.The influence of high continental pressures persists, with the consequent record of remarkable minimum temperatures.The moisture content is kept low, with a vapor pressure of 15.7 mm and a relative humidity of 75%.The total precipitation is the lowest in the year, averaging 54.9 mm and a frequency of 6 days with rain.
March is the fifth month of the rainy season in Cuba.The average rainfall totals are similar to those in February.Rainfall depends mainly on frontal systems that affect the country, which have a frequency of affectation slightly lower than the previous month.Winds of the southern region usually occur, sometimes strong, which constitute one of the most important events of that month.Normally, in March the average temperature increases with respect to the previous two months, but it is still a cool or slightly cool month.
In April, the rainy season ends in our country, giving way to the rainy season that begins in May and extends until October.The high continental pressures begin to gradually weaken and sometimes there are some weak cold fronts, or they arrive in a state of dissipation with few associated rains.Another aspect of interest is the sures, which are wet and warm winds that persist for several days.This month presents high temperatures, with very variable thermal oscillation and anomalies in the regime of winds that can become strong.
In May, the rainy season begins in Cuba, although it does not occur simultaneously throughout the country, which extends until October and accumulates approximately 80% of the annual total. As a result, it is common for rain totals to increase noticeably since May, and are even abundant at times.
The beginning of the period of high activity of thunderstorms begins in June, although sometimes starts in May, this period does not start simultaneously in all regions and is manifested by a gradual increase in the occurrence of electrical storms, mainly during The afternoon and the first hours of the night, in association with the daytime heating.
June is on average the wettest month of the year in Cuba. A considerable part of the rainfall accumulation occurs associated with rainy events of several days, which occur mainly in the first two tens of the month. Rainfall depends on the influence of migratory systems in the tropical zone, such as tropical waves and lows, and their important interaction with mid-latitude systems.
There is also the beginning of the period of great activity of thunderstorms in June, which does not start simultaneously in all regions and is manifested by a gradual increase in the occurrence of electrical storms, mainly during the afternoon and early evening hours , In association with daytime heating. Direct involvement of tropical cyclones is rare, but when it does occur it often causes heavy rainfall. Normally, in June the average temperature increases with respect to May, and is sometimes a very hot month
July is the month that less rainfall contributes to the rainy season in Cuba. During this month, typical of summer in the northern hemisphere, there is a marked increase in the intensity of the Atlantic anticyclone and its influence on Cuba, which produces a considerable decrease in rainfall compared to the month preceding it. However, showers and thunderstorms occur mainly during the afternoon and early evening hours, associated with daytime heating and the passage of migratory systems in the tropical zone, such as tropical waves and lows.
Normally, in July the average temperature increases compared to June, and it is often a very hot month, one of the two hottest months of the year in Cuba.
August is the second month of the intra-season period and, therefore, one of the two months with the least precipitation contributing to the rainy season in Cuba, between May and October. During this month the remarkable influence of the Atlantic anticyclone on Cuba is maintained, which conditions that the precipitations are relatively scarce. However, showers and thunderstorms occur mainly during the afternoon and early evening hours, associated with the passage of migratory systems in the tropical zone, such as tropical waves and lows and daytime heating.
It is also a month in which the cyclonic activity on Cuba begins to increase, although the frequency of the hurricanes that affect it in that month is only half that of September. Normally, in August the average temperature increases with respect to June and July, and it is frequently a very hot month, the hottest of the year.
September is one of the rainiest months in Cuba. The influence of the Atlantic anticyclone decreases considerably with respect to July and August, which, together with the frequent passage of waves and tropical lows, leads to an increase in rainfall. September is also the month of greatest frequency of tropical cyclone formation in our region, which increases the cyclonic activity on Cuba significantly compared to August, although the frequency of the hurricanes that affect it in that month is somewhat lower To October. Associated with the direct or indirect influence of tropical cyclones, events of heavy precipitation occur in September. Normally, in September the conditions of intense heat typical of the summer in Cuba are maintained, although the temperature decreases slightly with respect to August.
October is the last month of the rainy season and summer, as well as the most important in terms of the occurrence of tropical cyclonic organisms. It is one of the rainiest months of the year: on average, rainfall totals of 173.6 mm and a frequency of 13 days with rain are reported. It is a month with a high moisture content (vapor pressure of 20.1 mm) and high relative humidity (81%).
November can be considered as a transition month between summer and winter conditions, coinciding with the beginning of the low rainy season, which runs through April. During this month the typical electrical storms of summer diminish notably and the cold fronts usually appear that with an average of 3, cross the territory. There is a decrease in the moisture content, the vapor pressure is 18.7 mm and the relative humidity is 79%.
December is one of the least rainy months of the year. The precipitation depends mainly on the cold fronts that arrive to the country, being characterized the same by their short duration and little intensity. The greater affectation of the cold fronts in relation to the previous month influences in the definitive establishment of the winter period. The moisture content is lower than in November, with vapor pressure values of 16.7 mm and relative humidity of 78%. On average, rainfall totals of 60.4 mm and a frequency of 7 days with rain are reported.
The climate of the city of Havana is tropical as in the rest of the island. However it receives a greater continental influence in winter, which makes the temperatures are cooler in these months and due to all these climatic goodnesses the city is visited throughout the year. There is a great oceanic influence in the climate, because the Gulf current passes against the coasts of the Cuban West. Rainfall is abundant in October and September and quite rare between March and May. In summer and Christmas is full of visitors who come to spend the holidays, winter and spring is invaded by foreign tourists who stay in luxurious hotels and private homes
