Heat index

The heat index value for May is computed to be a very hot 100.4°F (38°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Keep in mind the heat index values are meant for areas in shade and with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

In May, the average relative humidity is 73%.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
