Because of its location, Varadero is a quite windy place, which is positive in the hottest months, but should be taken into account with regard to the cool season. In fact, during winter, from mid-November to mid-March, here as elsewhere in the north of Cuba, a cool wind from the United States, the Norte, can blow, associated with cloudiness and some rain. In these cases, at night the temperature can drop to 10/12 °C (50/54 °F).

From June to November, Varadero like the rest of the Caribbean can be affected by hurricanes, and in particular the period in which they are most likely runs from August to October.



The amount of sunshine in Varadero is good all the year round. In the wettest period, which as mentioned runs from May to October, showers and thunderstorms do not reduce the sunshine duration by much, since they are generally short-lived. Instead, from November to February the sun often shines, but there can also be the passage of cloud banks, linked to outbreaks of cool air from the north, which we have already spoken of.

For swimming, the sea is quite warm even in winter, when it's about 24/25 °C (75/77 °F), while it becomes very warm in summer, as it reaches 30 °C (86 °F) in August.

The best time to go to Varadero runs from December to May, although it might be useful to make some distinctions: from December to February, and sometimes in the first half of March, it can get cool for beach life, and there may be clouds and rain: in these cases you can go hiking in the interior of Cuba, to visit the nearby cities of Matanzas and Cárdenas, and perhaps the capital Havana; however, it's better to bring a sweatshirt (and maybe also a light jacket) and long pants. On the contrary, in May the sultry heat begins, as well as thunderstorms, but you can still go because the hurricane season has not yet started. All in all, therefore, the best time goes from mid-March to late April.
In summer, for example in August, there's a humid heat, though sea breezes blow; showers and thunderstorms can be intense, but generally do not last long, and there's no shortage of sunshine; however, there is the danger represented by hurricanes.
