Remove the lens cover and let your camera aclimatise to the environment before shooting, this will help prevent condensation forming. Remember to replace the lens cover before exposing it to water.

Leave the Side door open to allow air to circulate through the camera. If possible, allow the unit to dry in an air conditioned and/or low humidity environment (<50% humidity) until signs of fogging have dissipated. If the fogging continues, our Support team at https://gopro.com/help/ContactUs will be able to help you with the next steps. You may reach them by phone or chat.
