Weather in April
Temperature
With the start of April, Alas measures an average high-temperature of a still warm 27.8°C (82°F), not significantly differing from March's 27.6°C (81.7°F). A consistent average low-temperature of 24°C (75.2°F), with a minor variance from the daytime highs, is noted during the nights of April.Heat index
The heat index in April is appraised at a tropical 31°C (87.8°F). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Humidity
In April, the average relative humidity is 76%.Rainfall
In April, the rain falls for 21 days. Throughout April, 85mm (3.35") of precipitation is accumulated. Throughout the year, there are 201.9 rainfall days, and 906mm (35.67") of precipitation is accumulated.Daylight

Sunshine
In April, the average sunshine is 9h.UV index
The months with the highest UV index are March through May, September through November, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for average individuals.Note: In April, the maximum UV index of 7 suggests this advice:
Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
