I have never had worries about flipping a float tube in the wind. But waves breaking over the tops of your tube and into your waders can be chilly. It can be a challenge to get back to where you are parked if a stiff off shore wind kicks up. (Like at Antero, Spinney or 11 mile). Good to know where the afternoon wind will come from and park on the other side so you most likely get blown towards your Vehicle rather than the other side of the res. Or stick to coves with some shelter from the wind.
