October weather forecast
Saul, French Guiana

October expands upon September's trend but curtails the length of daylight hours. More sunlit days, complemented by longer sunshine hours of 8.8 hours per day, are the norm this month. Light seasonal winds blow across Saul, keeping the weather pleasant and balmy. Temperatures swing around relative highs and lows, maintaining a balanced weather pattern. As October winds down, Saul starts gearing up for the transition back into its rainy phase.

Temperature

October is the month when Saul sees the highest average temperatures, with a high of 34.9°C (94.8°F) and a low of 20.8°C (69.4°F).

Heat index

For October, the heat index is evaluated at a burning hot 51°C (123.8°F). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

With an average relative humidity of 72%, October is the least humid month.

Rainfall

The month with the least rainfall is October, when the rain falls for 10.4 days and typically collects 21mm (0.83") of precipitation.

UV index

Follow precautions and abide by sun safety rules. Deterrence of sunburn is imperative. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
