Weather in October
Temperature
The dawn of October sees an average high-temperature of a still warm 29.4°C (84.9°F), subtly contrasting with September's 29.5°C (85.1°F). Throughout October, an average low-temperature of 20.7°C (69.3°F) is experienced.Heat index
October's average heat index is estimated at a very hot 36°C (96.8°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'felt air temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Proceed with care. Light skin individuals may be exposed to burns in fewer than 30 minutes. Solar radiation peaks around mid-day, so it's wise to limit exposure to the Sun at this time. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
