Weather in August
Temperature
Fresno's warmest month, August, generally records average temperatures ranging from a high of 92.8°F (33.8°C) to a low of 76.6°F (24.8°C).Heat index
In August, the heat index is calculated to be a blazing hot 118.4°F (48°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.Understanding the heat index involves considering values for shaded locales with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Sunshine

The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for ordinary individuals.Note: In August, a daily maximum UV index of 7 leads to the following instructions:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
