Should You Open or Close Your Windows When It’s Hot? ›

Generally, if your house is decently insulated, keep the windows and blinds closed when the sun is shining. Open the windows in the evening and at night. More specifically, keep the windows closed when the outside temperature is hotter than it is inside, and open the windows when it's cooler outside than inside.

The basic rule of thumb is that you should close your windows when the temperature outside starts to exceed the temperature inside. It may seem counterintuitive, but as the temperature climbs, you'll often make your home warmer, not cooler, by opening the windows.

Although it's easy to imagine that flinging your windows wide might invite some hint of a cool and pleasant breeze, in all likelihood, you'll just be bringing warm air in – making your living space even hotter.
