The weather on Cozumel and Isla Mujeres is usually what you hope for… perfect! The average temperature is around 80 degrees, with the hottest month (August) around 82°F and the coldest (January) around 75°F. Of course, while you’re on either island you’ll see these in Celsius (28°C and 24°C, respectively). Any way you look at it, the temperature is perfect. The humidity, however, can make that August high of 85° feel much closer to 100°!
