In summer, set a ceiling fan to rotate counterclockwise to create a downdraft that pushes cool air downward, which makes you feel cooler. If you’re uncertain about your specific fan, a quick test—stand under the fan and feel for a breeze when it’s on—will confirm the direction is helping you stay cool. Guidance by common practice
- Primary rule: summer = counterclockwise rotation to push air downward.
- Speed: higher speeds move more air, but even at moderate speeds you’ll often notice the cooling effect.
- Seasonal adjustment: switch to clockwise in winter to pull warm air downward and distribute it more evenly (useful in rooms with high ceilings or drafty areas).
Tips for accuracy
- If your blades’ pitch or design seems unusual, test the breeze direction by standing under the fan and noting where the air feels strongest.
- For large rooms or high ceilings, ensure the fan is appropriate for the space and consider blade length or additional fans if needed.
