September weather forecast
Galibi, Suriname

September in Galibi sees a further dip in temperature and rainfall, recording a minimal rainfall amount of just 26mm (1.02"). This drastic decrease in rainfall, combined with reduced cloud coverage, makes this one of the driest months in the city. Despite the lowering of the rain gauge, temperatures remain warm, keeping the climate largely comforting and pleasant.

Temperature

Galibi observes a minor difference in average high-temperatures between August's 32°C (89.6°F) and September's 32.7°C (90.9°F). The nights of September in Galibi anticipate an average low-temperature of 22.5°C (72.5°F).

Heat index

During September, the heat index is evaluated at a blazing hot 47°C (116.6°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Employ a wide-brim hat for potent defense against up to 50% of UV rays.
