IT'S TOO HOT

Leave your windows open overnight, when the temperature is cooler

This let the cooler outside air in, bringing the temperature down inside

Close windows in the morning when the temperature starts to rise

Having windows open is only a benefit when the temperature outside is lower than inside. If you leave your windows open during the day, then you may be allowing hot air in

Closing all curtains and blinds will further help to keep the heat out

Whilst this may mean you're sitting in the dark, it will stop the sun from increasing the temperature inside your property

If the air outside is cooler than the air inside, put the fan with its back to the window

This will blow the cooler air into the room and lower the room temperature.

If it's the opposite, do the opposite

The fan facing the window will blow the warmer air out and helps lower the temperature in the room
