Heat index

July's average heat index is computed to be a sweltering 35°C (95°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Consider that heat index readings are for situations in the shade and light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

In July, the average relative humidity is 77%.

UV index

The months with the highest UV index are January through September, November and December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.
Note: In July, the maximum UV index of 6 translates into these guidelines:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
