Weather in July
Temperature
The warmest time of the year is July, with temperatures averaging a high of 82°F (27.8°C) and a low of 61.9°F (16.6°C).Heat index
The heat index in July is appraised at a tropical 86°F (30°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
