Weather in July
Temperature
July, with its average high-temperature of 81°F (27.2°C) and an average low-temperature of 64.2°F (17.9°C), holds the record as the warmest month.Heat index
For most parts of July, the heat index is estimated at a tropical 87.8°F (31°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
