October weather forecast
Caledonia, Guyana

October, like September, is a hot autumn month in Caledonia, Guyana, with an average temperature fluctuating between 23.5°C (74.3°F) and 32.9°C (91.2°F).

Temperature

The dawn of October sees an average high-temperature of a still hot 32.9°C (91.2°F), subtly contrasting with September's 33.1°C (91.6°F). Nightly temperatures drop to an average low of 23.5°C (74.3°F) in October.

Heat index

October's mean heat index is computed to be a life-threatening hot 47°C (116.6°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
