Would you reccon I'd need a pretty warm fishing pants for sept-oct? Always did midsummer fishing, but wanted to try something new this year. Didn't really need any special clothes for summer since water is mostly decent temp, but trying it out in fall kinda makes me worried.Rule in the kayak is to have everything connected/lashed down, assume you will dump over and at the worst possible time and plan for that, but practice and fish in such a way to minimize the possibility.
Also for early or late, dress for the water temp, not the air temp.
You always dress to wind up in the water. Can you swim and will you get hypothermia being the main concerns. I wear my surfing wetsuits to fish the kayak as things cool off into December.
