Weather in July
Temperature
July, with its high-temperature average of 81.7°F (27.6°C) and a low-temperature average of 64.9°F (18.3°C), is the warmest month.Heat index
The heat index value during July is calculated to be a hot 86°F (30°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. 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 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
