March weather forecast
Liberia, Costa Rica

The month of March signals the onset of a drier season in Liberia. The weather generally remains steady with slight changes in various elements. The temperature, both at its peak and trough, showcases a minor increase compared to February, while the days are slightly longer, allowing more daylight. This results in extended hours of sunshine on most days of the month. There is a noticeable drop in rainfall to 1mm (0.04") down from 2mm (0.08") during February, representing the start of the dry season.

Temperature

The arrival of March in Liberia brings an average high-temperature of a still tropical 33.8°C (92.8°F), subtly diverging from February's 32.3°C (90.1°F). An average nighttime temperature of 22.9°C (73.2°F) is noted in Liberia during the month of March.

Heat index

During March, the heat index is estimated at an extremely hot 43°C (109.4°F). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

In Liberia, the average relative humidity in March is 63%.

UV index

January through October and December, with an average maximum UV index of 7, are months with the highest UV index in Liberia. A UV Index of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: A daily maximum UV index of 7 in March translates into the following instructions:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
