Weather in July
Temperature
The warmest month is July, with an average high-temperature of 83.3°F (28.5°C) and an average low-temperature of 61°F (16.1°C).Heat index
The heat index in July is computed to be a tropical 89.6°F (32°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. 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 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
