October weather forecast
Ilopango, El Salvador

As October rolls in, Ilopango residents brace for damp days due to the rise in rainfall up to 223mm (8.78"). However, the city compensates with an increase in the average hours of sunshine up to 8.3, albeit amidst 40% cloud coverage. Wind speeds pick pace to 5km/h (3.1mph) hinting at the imminent change of season. October, therefore, is a month of transitions and a confluence of multiple elements.

Temperature

In Ilopango, the lowest average temperatures are observed in October, with a high of 29.7°C (85.5°F) and a low of 20.5°C (68.9°F).

Heat index

The heat index value for October is estimated at a torrid 37°C (98.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
