Weather in July
Temperature
The warmest month is July, with an average high-temperature of 81.9°F (27.7°C) and an average low-temperature of 65.7°F (18.7°C).Heat index
The heat index value during July is estimated at a tropical 87.8°F (31°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
