Weather in July
Temperature
July, noted for its average high-temperature of 82.2°F (27.9°C) and an average low-temperature of 61.2°F (16.2°C), is considered the warmest month.Heat index
July's average heat index is estimated at a tropical 89.6°F (32°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.

Ward off overexposure. Defence against solar harm is crucial. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
