Weather in July
Temperature
The advent of July denotes an average high-temperature of a still hot 32°C (89.6°F), subtly different from June's 30.7°C (87.3°F). During the nights in July, San Francisco Lempa experiences a consistent average temperature of 21.1°C (70°F).Heat index
The heat index in July is appraised at a scorching 43°C (109.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 hold particular importance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
