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

As Cozumel welcomes February, the average high-temperature stabilizes at a still warm 29.1°C (84.4°F), showing little deviation from January's 28.6°C (83.5°F). An average nighttime temperature of 19.4°C (66.9°F) is witnessed throughout February.

Heat index

February's heat index is computed to be a sweltering 35°C (95°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In February, the average relative humidity is 81%.

Rainfall

UV index

In February, the average daily maximum UV index is 9. A UV Index reading of 8 to 10 represents a very high threat to health from exposure to the Sun's UV radiation for average individuals.
Note: The maximum daily UV index, 9 in February, converts into the following recommendations:
Take extra precautions. Fair-skinned individuals may get burned in less than 10 minutes. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Regularly apply and reapply a broad-spectrum sunscreen with a minimum SPF 30 every two hours, or straight after swimming or an outdoor activity. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
