Heat index

During May, the heat index is calculated to be a fiery hot 38°C (100.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

UV index

February through May, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for average individuals.
Note: In May, a daily UV index of 6 turns into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
