Heat index

In October, the heat index is computed to be a blistering 40°C (104°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

In October, the average relative humidity is 82%.

UV index

The average daily maximum UV index in October is 10. A UV Index reading of 8 to 10 represents a very high threat to health from exposure to the Sun's UV radiation for ordinary individuals.
Note: The maximum daily UV index of 10 in October interprets into the following recommendations:
Protection should always be a priority. Skin and eyes are vulnerable without it. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Sunscreen with a sun protection factor of no less than 30 should be used liberally and reapplied frequently on overcast days, including after every swim or outdoor activity.
