I do much the same thing. At night, I leave the house partly open so
that it cools down. In the morning, I close all the doors and windows
to trap in the cold air. At about noon, the house warms up to the
same as outside temperature, so I open with windows.

I like to do the same thing when we have cool nights like tonight. More
important than cooling the air in the house is cooling the house itself.
Air heats and cools quickly, the materials of the house, not so much.
So let the house cool as much as possible then shut the house when the
temperatures start to rise. I can't remember the house ever reaching
the outside temperature by noon, the equal point is usually in the
evening when the outside starts to cool again.
