September weather forecast
Cojutepeque, El Salvador

September ushers in a mild decrease in the average all-day temperature. The humidity, rainfall, and cloud cover, however, continue to reign high marking the peak of the rainy season. The average visibility drops to its yearly low at 7km (4.3mi) due to the frequent showers, wrapping Cojutepeque in a mystical, rain-drenched aura.

Temperature

September brings an average high-temperature of a still hot 30.9°C (87.6°F), showing a slight difference from August's 31.8°C (89.2°F). In the month of September, Cojutepeque records a consistent average low-temperature of 20.5°C (68.9°F).

Heat index

September's mean heat index is estimated at a blisteringly hot 41°C (105.8°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In September, the average relative humidity is 82%.

Shield from overexposure. Defense against sun-related harm is required. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
