February weather forecast
Cozumel, Mexico

In February, the weather starts to shift with a decrease in rainfall compared to January. Daylight hours gradually increase, signaling the approach of warmer seasons. A relative reduction in sea temperature stimulates aquatic life, making it a good period for underwater exploration. The UV index rises to 9, making shade and sun protection essential in avoiding harmful UV radiation. The daily temperature range varies between a minimum of 19.4°C (66.9°F) to a maximum of 29.1°C (84.4°F).

Temperature

The commencement of February notes an average high-temperature of a still warm 29.1°C (84.4°F), exhibiting little difference from the previous month. Cozumel registers a consistent average low-temperature of 19.4°C (66.9°F) during February.

Heat index

February's average heat index is calculated to be a very hot 35°C (95°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Humidity

In February, the average relative humidity is 81%.

Note: In February, a daily maximum UV index of 9 leads to the following instructions:
Prioritize protection; rapid damage can occur to unprotected eyes and skin. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. After a swim or outdoor exercise, one should liberally reapply broad-spectrum sunscreen with a sun protection factor of 30 or higher. Be alert! The reflection of water and sand augments UV radiation intensity.
