Someone linked a site once (on Reddit) and I didn’t bookmark either the post or the site :( but it was great - you used a sliding scale if I remember correctly for how much sun, wind, rain, snow, etc. close to ocean, mountains, etc. and it grayed out states and areas within a state to show you the remaining cities/areas that meet your requirements. Does this sound familiar to anyone? TIA!
From my googling it sounds like you’re looking for ClimateFinder? Thw one reddit post I could find (from 2016) had link to a dead PythonAnywhere project
