Weather in July
Temperature
July is the warmest month, with an average high-temperature of 81°F (27.2°C) and an average low-temperature of 64°F (17.8°C).Heat index
The heat index value during July is computed to be a tropical 87.8°F (31°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. 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. 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 particularly relevant to children. 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.
