In the summer, ceiling fans should generally rotate counterclockwise (or anticlockwise) when viewed from below. This direction creates a downward airflow, which helps create a cooling effect by creating a breeze in the room. The airflow created by the counterclockwise rotation can make you feel cooler by evaporating perspiration from your skin, providing a more comfortable environment.
To ensure your ceiling fan is rotating counterclockwise during the summer months, you can usually adjust the fan's direction using a switch located on the fan's motor housing. However, it's important to note that some ceiling fans may have different instructions or specific settings, so it's always recommended to consult the fan's manual for proper instructions regarding direction and operation.
