Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 81.9°F (27.7°C) and a low of 65.7°F (18.7°C).Heat index
The average heat index in July is calculated to be a tropical 87.8°F (31°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 hold particular importance for children.
