I agree that unless you go, you wont know.
But Ive fished enough slick calm, sunny days to know that most of the time days like that won’t produce as well .
I get that wind velocity keeps some off the water, or makes fishing like you want to next to impossible. But if you are fishing a small water body, or can stay stationary on the windy side of the lake, then it can often produce outstanding results.
I have generally done much better in lower light conditions, but not always. Sometimes everything is just right as you see it, but the fish dont cooperate.
In that case, I attribute the lack of bite to 1. The barometer not being conducive for a good bite.
2. The moon isnt in the best position for a good bite, or…
3. I havent found the fish. or…
4. They want a bait I havent shown them yet. or…
5. Im fishing those baits too fast ( usually the case) , or ( rarely ) too slow , or…
6. It’s so hot or cold it’s just shut them down. ( although I usually dont fish these conditions much anymore ).
But the older I get , I’m learning that I can overthink the whole thing, and taking it to an extreme , rarely go fishing.
Once I get on the water, I dont think about much , except finding the fish , and using a bait they want in a way they want it.
And once Im on the water, I almost never quit until the time I have set aside to fish is up.
And if they’re biting, there’s always another “ last cast “?.
