Those taking part in polar bear plunges on New Year's Day can at least take comfort in knowing the water will be warmer than the air.
High temperatures on New Year's Day are only expected to reach the mid to upper teens under mostly sunny skies. Lows will drop into the single digits Tuesday night before rebounding to around 20 degrees for a high temperature on Wednesday.
The extended forecast is predicting some pretty tame weather by January standards, with high temperatures in the 20s for the rest of the week and no significant snowfall expected.
The average high for Sturgeon Bay on January 1 is 27 degrees and the average low is 12. The record high temperature was 45 degrees, set in 2005. The record low was minus-17 (1969).
