October weather forecast
Guantanamo, Cuba

October subtly initiates the fall season in Guantanamo, manifesting in the form of falling temperatures. Although rainfall remains high at 93mm (3.66"), temperatures gradually cool down, foreshadowing the forthcoming winter weather. As the city transitions from the tropical warmth of September, the mild climate combined with fading daylight hours ushers in the autumnal charm. Heading into November, expect conditions to become drier and a tangible dip in the temperature range. Notably, October’s weather transformation carefully walks the boundary between tropical summer and mild winter.

Temperature

October notes an average high-temperature of a still hot 30°C (86°F), subtly differing from September's 30.9°C (87.6°F). Guantanamo records an average temperature drop to an agreeable 22.9°C (73.2°F) in October.

Heat index

The heat index in October is calculated to be a very hot 38°C (100.4°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
