Weather in July
Temperature
With an average high-temperature of 85.8°F (29.9°C) and an average low-temperature of 68.9°F (20.5°C), July is the warmest month.Heat index
The heat index in July is appraised at a sweltering 95°F (35°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
