April weather forecast
Catió, Guinea-Bissau

April marks a transitional period into the wet season in Catió. There is a slight dip in temperature from March, but still, it remains quite warm, creating an aesthetic of tropical weather. Commensurate with this shift, rainfall begins to increase, preparing the landscape for a more humid environment. The period of daylight extends further, providing an opportunity for longer daytime activities. Despite the rising humidity and occasional showers, the city’s climate remains favorable for various outdoor events.

Temperature

The initiation of April records an average high-temperature of a sweltering 39.5°C (103.1°F), displaying a near consistency with the previous month. Catió registers a substantial downturn from daytime peaks throughout April nights, with an average low-temperature of 20.8°C (69.4°F).

Heat index

April's mean heat index is estimated at a blazing hot 53°C (127.4°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Note: The maximum daily UV index of 7 in April interprets into the following recommendations:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
