Guessing the wind - in the absence of a windsock or, not seeing one tucked away behind a barn - can be a bit of a gamble
If you're flying to one without a windsock, it makes sense to have a GPS with you, and ensure it's showing ground speed before you commence your approach. Compare it to your IAS and you'll soon know if you have a tailwind, although this can (and often did, in my experience) change in the last couple of hundred feet, so be ready to go around.
