Weather in July
Temperature
July, on average, is the warmest month, registering a high temperature of 84°F (28.9°C) and a low of 61.9°F (16.6°C).Heat index
The average heat index in July is estimated at a tropical 93.2°F (34°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
