How do you handle the stifling summer humidity and hurricanes in Houston?
Air conditioning and a house built to code.
There is a new technology: Air conditioning.
In western Texas they supplement that with swamp coolers, at the cost of some water, the electricity required for cooling is cut to 1/7th to 1/14th. The other thing you do to manage climate is to schedule your activity. Summer mornings at 5:00AM are pretty pleasant. Winters about 3:00PM are pretty pleasant. In southern CA you do the same thing, but schedule around the traffic.
I grew up in Texas with no a/c
Now would be tough
As to hurricanes they are few and far between
Unlike tornadoes and earthquakes you can outrun them easily
I have lived also in England, connecticut( next to newtown) California and Louisiana and Texas is by far the best
