October, like September, is another tropical autumn month in Suna, Guinea-Bissau, with an average temperature varying between 34.7°C (94.5°F) and 23.5°C (74.3°F).

Temperature

The start of October brings a subtle rise in the average high-temperature, moving from 31.7°C (89.1°F) in September to a still tropical 34.7°C (94.5°F). October nights experience a consistent temperature drop to a warm 23.5°C (74.3°F).

Heat index

In October, the heat index is appraised at a blazing hot 52°C (125.6°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
In the scope of the heat index, its values resonate with shade and light wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

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. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
