Weather in July
Temperature
With average temperatures fluctuating between a high of 80.6°F (27°C) and a low of 58.8°F (14.9°C), July stands out as the warmest month.Heat index
The heat index for July is computed to be a tropical 86°F (30°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
