March weather forecast
Santa Rosa de Lima, El Salvador

As Santa Rosa de Lima transitions from February to March, there's an onset of early tropical vibes. The city experiences the highest UV index of the year, compelling locals and tourists to take extra precautions. Even though the weather grows gradually warmer with an average high temperature of 35.1°C (95.2°F), an increase in daylight hours, from 11.7 hours to 12.1 hours, ensures that the city remains enlivened. Rainfall escalates to 6mm (0.24"), hinting at the rainy period ahead. Yet, the quick seaside showers only add charm to the sunny ethos.

Temperature

March and April represent the warmest period, with an average high-temperature of 35.1°C (95.2°F).

Heat index

For March, the heat index is evaluated at a blistering 43°C (109.4°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Experience reduced UV exposure by about half when donning a wide-brim hat.
