Weather in July
Temperature
July, characterized by an average high temperature of 82.9°F (28.3°C) and a low temperature of 66°F (18.9°C), is generally the warmest month.Heat index
The average heat index in July is computed to be a tropical 91.4°F (33°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
