Weather in July
Temperature
July registers as the month with the highest average temperatures, reaching 85.8°F (29.9°C) at its peak and 64.6°F (18.1°C) at the lowest.Heat index
For July, the heat index is appraised at a hot 91.4°F (33°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. 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.
