Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 81°F (27.2°C) and an average low of 64.4°F (18°C).Heat index
Throughout July, the heat index is calculated to be a tropical 87.8°F (31°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Know that the heat index computations account for shaded terrains and slight winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
