Weather in July
Temperature
With average temperatures fluctuating between a high of 81°F (27.2°C) and a low of 64.8°F (18.2°C), July stands out as the warmest month.Heat index
For July, the heat index is evaluated at a tropical 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. 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 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
