The arrival of October in Havana coincides with an average high-temperature of a warm 29.2°C (84.6°F), indicating a minimal shift from September's 31°C (87.8°F). An average low-temperature of 23°C (73.4°F) is noted during the nights in October.

Heat index

The heat index for October is appraised at a sweltering 35°C (95°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key. Even on a cloudy day, a sunscreen with at least a 30 SPF should be applied generously and frequently reapplied, including after a swim or outdoor exercise. Be careful!
