This time of year I start to focus on wind speeds coupled with temps especially when ice is for sure on its way out. A windy 45 degree day can eat up white ice, especially along the shores and real shallow bays. You may be able to acces the lake at 8am but by 3pm the shore is shot. Been there, done that. A day or two’s worth of warm up depends mostly on wind, rain, and current ice conditions.
Not knowing you’re exact area and conditions, I can’t tell you anything that’s already been said.
I’m not new to ice fishing by no means but I’m still somewhat new to learning ice conditions. If I were you, I’d take my gear (enough to fish) along with a spud. Spud out the shore where you’re going to accessing the lake from to see how that access will be then once you’re on (even a few feet if water is deep enough) drill a hole to see the composition layers of the ice (white ice surface/slush/ black ice/gaps) then continuously spud AHEAD of you drilling another hole every 10-20 yards until you come to a conclusion about ice safety. ONLY YOU can determine what safe ice means for yourself. Even with bad ice on top, I like seeing at least 4” of solid ice on the bottom. White ice (frozen slush/aerated ice) needs twice the thickness of black ice to support the same weight.
