Weather in August
Temperature
August is the month when San Mateo sees the highest average temperatures, with a high of 91.9°F (33.3°C) and a low of 75.4°F (24.1°C).Heat index
During August, the heat index is evaluated at a burning hot 118.4°F (48°C). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. 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 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. 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. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
