Weather in May
May, the last month of the spring in Catarina, is another tropical month, with an average temperature varying between 31.4°C (88.5°F) and 25.1°C (77.2°F).Temperature
May's onset records a minor alteration in the average high-temperature to a still hot 31.4°C (88.5°F) from April's 31.8°C (89.2°F). During the month of May, Catarina's nighttime temperature lowers to an average of 25.1°C (77.2°F).Heat index
In May, the heat index is estimated at a sweltering 39°C (102.2°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. 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. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.Note: A typical high UV index of 7 in May suggests the following recommendations:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
