August weather forecast
Catió, Guinea-Bissau

August upkeeps the wet dominant climate in Catió, replicating July’s rainfall patterns with a subtle increase. It is recognized for gearing up the atmosphere for an onset of cooler autumn months. Although August remains dominated by the rain, it exhibits a promising pattern of weather transition towards the end of the month. The month witnesses the least amount of sunlight in the year, owing to dense cloud cover. With the highest percentage of cloud cover in the year, it makes for some spectacular sunset views against the contrasting bright colours of dusk.

Temperature

In Catió, the month of August registers the lowest temperatures, averaging 29.9°C (85.8°F) at the peak and 23.8°C (74.8°F) at the lowest.

Heat index

For most parts of August, the heat index is estimated at a sweltering 39°C (102.2°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. 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.
