January weather forecast
Mejicanos, El Salvador

January sweeps to Mejicanos, El Salvador with moderate temperatures that happen to be a tad cooler than those in February. It fosters a calm atmosphere with limited cloud cover, paving the way for substantial daylight and sunshine hours. January's climate is marked by clear skies, complete with a reinforcing pressure of 1013.5mb and a gentle breeze flowing at 8.5km/h (5.3mph). However, there is a relatively low-rated UV index of 6. On the other hand, the rainfall registers at merely 1mm (0.04"), making rainfall scarcity a notable aspect of January's weather profile.

Temperature

Mejicanos experiences a recorded average high-temperature of a tropical 30.6°C (87.1°F) in January, closely aligned with December's 29.9°C (85.8°F). Mejicanos reports a consistent average low-temperature of 19.4°C (66.9°F) throughout January nights.

Heat index

January's mean heat index is evaluated at a torrid 35°C (95°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Note: A maximum UV index of 6 in January translates into the following recommendations:
Inhibit overexposure. Warding off sun damage is of utmost importance. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
