May weather forecast
Vinales, Cuba

May in Vinales denotes a transition to a more tropical climate, characterized by hot temperatures, high humidity, and torrential rains. A striking feature dictated by the data for this month is an upsurge in rainfall amounts that reach 90mm (3.54"), nearly thrice that of April. The sun continues to shine brightly for up to 10.4 hours per day despite the afternoon thunderstorms, commonly witnessed this month. Alongside this, the temperatures maintain their highs, making it one of the warmest months. Beneficially, steady breezes offer some relief from the heat and humidity.

Heat index

For most parts of May, the heat index is estimated at a fiery hot 38°C (100.4°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
