Just like a tricycle aircraft you can land a tail-dragger in almost any windspeed so long as it's on the nose; a wheelie is easiest when it's very strong.
But unlike a tricycle, that's when the fun begins; there will be moments when a wing-person is essential to help you turn away from the wind, due to "weather-cocking".
I was once stuck, humiliatingly, right at the end of the Bahrain runway for nearly 10 minutes, effectively closing it, while a team was assembled to be driven to help me turn onto the taxiway. The wind was about 25 Kts, and the aircraft was a Prentice with poor brakes (there was no other kind).
