In Cozumel, Mexico, the average high-temperature in October is essentially the same as in September - a still hot 30.7°C (87.3°F). The average low-temperature, in Cozumel, is 23.1°C (73.6°F).
In October, the average heat index is appraised at a blistering 41.6°C (106.9°F). Be wary - heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'feels like', 'felt air temperature', 'apparent temperature', or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like metabolic differences, pregnancy, differences in body mass, height, and shape, and activity influence one's weather impression. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
In Cozumel, the average relative humidity in October is 85%.
The month with the most rainfall in Cozumel, Mexico, is October when the rain falls for 15.7 days and typically aggregates up to 242.5mm (9.55") of precipitation.

: For any water activity, surface water temperatures between 25°C (77°F) and 29°C (84.2°F) are considered as excellent and extremely pleasant for lengthened periods.

In October, the average sunshine is 6.2h.
The average daily maximum UV index in Cozumel is 9. A UV Index reading of 8 to 10 represents a very high health risk from the exposure to the Sun's UV rays for the ordinary person.Note
: The average daily UV index of 9 in October transform into the following instructions:
Take special precautions, as unprotected eyes and skin can be burned and damaged quickly. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
