Weather in October
Temperature
Richmond's weather in October indicates an average high-temperature of a still hot 30.3°C (86.5°F), nearly consistent with the 31.4°C (88.5°F) of September. An average nighttime temperature of 23.1°C (73.6°F) is noted during the month of October.Heat index
For most parts of October, the heat index is computed to be a fiery hot 39°C (102.2°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
