Weather in October
Temperature
The arrival of October marks a slight shift to an average high-temperature of a still tropical 31°C (87.8°F) from September's 31.8°C (89.2°F). Irakkamam's nighttime temperature in October drops to an average of 25.1°C (77.2°F).Heat index
For most parts of October, the heat index is appraised at a blisteringly hot 40°C (104°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.Note: In October, a daily maximum UV index of 7 leads to the following instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
