When it comes to open water, I’m with you on the jet skis and pleasure/speed boats. Other than that, slight overcast with only a slight breeze. I like to target multiple species when given the chance, so surface temp in the low 70s and cooler water out just a little deeper so I can go for panfish and bass, or just go a little deeper for trout. Of course being able to catch some quantities with some quality sized fish mixed in. I love ice fishing maybe a bit more, so perfect day would be no snowmobiles racing around, slight overcast no wind and warm enough to fish in just a sweater.
All that said, any day that I can actively use my electronics and get to play my favorite video game gets a plus in my book. Now that I have a panoptix unit, those days will hopefully not be limited to the ice.
