Weather in October
Temperature
October and November represent the warmest period, with an average high-temperature of 34.3°C (93.7°F).Heat index
The heat index in October is appraised at a very hot 39°C (102.2°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
