Temperature

Fillmore's warmest weather arrives in August, when temperatures average a high of 94.1°F (34.5°C) and a low of 72.9°F (22.7°C).

Heat index

In August, the heat index is computed to be a blistering 111.2°F (44°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
