Weather in May
Temperature
Catarina observes a slight uplift in the average high-temperature with the onset of May, adjusting from April's moderately hot 85.6°F (29.8°C) to a tropical 91.2°F (32.9°C). Catarina sees an average low-temperature of 70.3°F (21.3°C) during May.Heat index
May's mean heat index is computed to be a torrid 102.2°F (39°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Sunshine
The average sunshine in May is 9.1h.UV index
In Catarina, the average daily maximum UV index in May is 7. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for average individuals.Note: In May, a regular UV index of 7 translates into these guidelines:
Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
