The transition into July reveals an average high-temperature of a still hot 32°C (89.6°F), mirroring a close resemblance to June. During July, San Francisco Lempa experiences a consistent low-temperature average of 21.1°C (70°F).Heat index
The heat index value during July is appraised at a blisteringly hot 43°C (109.4°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
