I like coolness in my house, and trap night air inside.
If it’s gray in the morning and you water your garden, what I do is close windows to keep humidity* outside instead of blowing in.
fanIf/when later the wind becomes cooler than your home, create a wind tunnel by opening windows on each side. If not strong enough, placing intake (Western** windows) and outflow fans (East) helps.

*gaseous water vapor evaporating off plants and ground (Once in, humidity is trapped and hard to get out unless you have a dehumidifier or A.C.).
**”usually” where the sun sets, according to the latest TFI Poll
(TwitterFacebookInstagram, 77% of users, 16% “unsure,” 4% “no opinion,” 3% blank).
