Great question Theresa,
My absolute session abort is wind speeds of 8-9 mph and greater.
If the wind is blowing toward my launch site then I may launch so that it will blow me right back to my launch site ... once my legs get fatigued.
I've also noted that it's not only the wind that I have to contend with but the wind also moves the top surface of the water in the same direction as the wind as well ... this is when it can become over whelming. So now you are kicking not only against the wind but against the moving water as well. puff puff.
And ... if in a tidal situation ... one needs to consider the IC and OG tidal movements because this will greatly amplify the situation along with the wind and IC /OG water movements, depending on the direction of the tide.
And like Fishbones805 had mentioned ... coordinate your fishing AO's (area of operation) with the wind direction accordingly.
For example ... If the wind is blowing from the N to S direction, fish along the N edge where you will be tucked up against a ridge/ hill/ jetty/ wall/ tree line and be somewhat sheltered.
Heck ... the fish may be doing the same exact same thing ... using shelter!
lol
PS ... wear a wind breaker, be safe and good luck to you out there,
SP Dan <"))><
