October weather forecast
Guatemala, Cuba

October, like September, in Guatemala, Cuba, is a moderately hot autumn month, with an average temperature fluctuating between 29.8°C (85.6°F) and 22.5°C (72.5°F).

Temperature

October's presence marks an average high-temperature of a warm 29.8°C (85.6°F), subtly varied from September's 31°C (87.8°F). The nighttime temperature, during October, averages of 22.5°C (72.5°F).

Heat index

The heat index in October is calculated to be a torrid 38°C (100.4°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

The most humid month in Guatemala is October, with an average relative humidity of 84%.

Rainfall

UV index

January through April, October through December, with an average maximum UV index of 6, are months with the lowest UV index in Guatemala. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: The maximum UV index of 6 during October leads to these instructions:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. 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. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
