The water temp now is colder than it was at this time over the last few years. When it warms up a bit, so will the bite.
If you have to get out there to beat cabin fever, I would fish deeper 25-32 FOW until it warms. Also, check shallower if we get a much warmer day or two. Fish where the wind has pushed warmer water up towards the shoreline. Keep moving, if you are in a spot and haven't had any action in 10-15 minutes, move on and try something different.
