Weather in April
Temperature
As April arrives, a slight rise in the average high-temperature is observed, moving from a moderately hot 82.2°F (27.9°C) in March to a tropical 89.1°F (31.7°C). Throughout the month of April, Havana observes an average nighttime temperature of 67.8°F (19.9°C).Heat index
The heat index value during April is estimated at a torrid 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
