April weather forecast
Tambor, Costa Rica

April ushers in a significant shift in the weather conditions in Tambor. The climate continues to warm, with prolonged daylight intensifying the heat. Compared to the previous month, April experiences a striking spike in rainfall, rising to 47mm (1.85") from 8mm (0.31"), signaling the commencement of the wet months ahead. Still, the UV index remains constant, so precautions to protect skin from ultraviolet radiation are crucial. Despite increased rainfall, there are still many sunny spells that are long enough for beachgoers to enjoy the sea.

Temperature

Tambor notes the warmest temperatures in April, with a high average of 32.3°C (90.1°F) and a low of 24.3°C (75.7°F).

Heat index

For most parts of April, the heat index is appraised at a blistering 40°C (104°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. 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. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Alert! Sand and water increase UV exposure due to their reflective properties.
