Havana, “It is usual for high temperature values to be reported throughout the country in June,” said researcher Ramón Pérez Suárez, just at the time when the thermometer in his living room marked 33 degrees Celsius. “This is one of the hottest months of the year, along with July, August and September,” he added.

What about the national record in June? According to the specialist, the most notable record was reached in 2004, specifically the first day at the Jucarito station, in the province of Granma: 38.6 degrees Celsius. Ramón also recalled – regarding the heatwave and its numbers – that the average temperature in Cuba in the June-July-August quarter increased in 0.8 degrees between 1951 and 2017. The climate has become warmer!

Followers of Ráfaga 340, we learned through Armando Caymares Ortiz, meteorologist of the National Center for Forecasts, that last Saturday were measured at Veguitas 37.7 degrees Celsius. Although it is a relevant temperature value, it is not higher than the one obtained in the same locality of Granma in June 2017. Veguitas also stood out for its maximum records in 2015 and 2018.

Even at night the heat is overwhelming. As announced by Insmet, on Sunday the minimums were between 24 and 27 degrees Celsius, and the most interesting were: 28.8 (in Varadero), 28.6 (Cayo Coco) and 28.0 (Cabo Lucrecia).

If it doesn’t rain…

The environmental temperature tends to decrease as a summer storm approaches and as it rains. On the other hand, with a clear or lightly cloudy sky in the morning and early afternoon – as we have had in much of the archipelago in recent days – the air around us warms up quickly. Warming is stronger in remote coastal areas, where the wind is weaker.

Along with the dominance of high oceanic pressures, Saharan dust has been present in Cuba. According to Rubiera, this implies a decrease in rainfall and a sensation of great heat.

Even more than 40

Not only does the temperature given by the thermometer determine the sensation of heat; there are other parameters.

As an example, reaching 34 degrees Celsius in the weather station of the Universidad de Oriente. If in the city of Santiago de Cuba the humidity is high, the wind is light or calm and we expose ourselves to the sun, we will feel much more than those 34 degrees, let’s say 42, 44…

Age, sex, body weight, level of physical activity and the clothing we wear are all factors involved in thermal sensation.

And don’t forget that the walls and roofs of buildings and paved streets easily absorb solar radiation and expel heat at night.
