Weather in April
Temperature
In Alfaro, the months of March and April are known for the peak temperatures, reaching an average high of 29.7°C (85.5°F).Heat index
The heat index value during April is calculated to be a very hot 35°C (95°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
