Weather in July
Temperature
July proves to be the warmest month, recording an average peak temperature of 81°F (27.2°C) and a minimum temperature of 58.6°F (14.8°C).Heat index
Throughout July, the heat index is evaluated at a tropical 86°F (30°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
