Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 81°F (27.2°C) and a low of 64.6°F (18.1°C).Heat index
The heat index value during July is computed to be a hot 87.8°F (31°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
