Heat index

Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

In May, the average relative humidity is 74%.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
