Heat index

June's mean heat index is calculated to be a torrid 35°C (95°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Humidity

The months with the highest humidity are June and September, with an average relative humidity of 82%.

Note: The daily high UV index of 7 in June translates into this advice:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
