Well, well, well. December in Wisconsin has apparently forgotten its job description. Today at Jack Lake, we’re looking at a high of 59°F and a low of 43°F under mostly cloudy skies. The wind starts at 8 mph ENE this morning, which is practically a gentle caress by winter standards. Someone alert the authorities—this is suspiciously pleasant.

The 7AM-7PM Paddling Window

Let’s break down this meteorological miracle. You’ll start the morning at 7am shivering slightly at 43°F with 8 mph winds pushing from the east-northeast. By 10am, temperatures climb to 52°F with wind picking up to 10 mph E—the day’s peak gust, if you can even call it that. The sweet spot hits between 2pm and 4pm when temps plateau around 58-59°F and wind mellows back to 8-9 mph. Late afternoon sees the mercury gently retreat to 54°F by 7pm with winds dropping to a lazy 6 mph. If you’re hunting for the best window, aim for that 2pm-5pm stretch when conditions are as good as they’ll get.

Through the Day

Early birds at 7am face 43°F and 89% humidity—so thick you could practically chew the air. By 9am you’ve warmed to 49°F with 9 mph winds, and humidity finally starts behaving itself, dropping to 83%. The midday hours from noon to 3pm deliver consistent 55-58°F temperatures with 9 mph easterly winds keeping things interesting on the water. As evening approaches, expect 56°F at 6pm with 7 mph winds and conditions shifting to fully cloudy before clearing slightly again.

Who Should Actually Paddle Today

This is a day for the pleasantly confused paddler who packed layers expecting hypothermia and got… this. With winds averaging 8 mph all day, you’ll get a gentle workout without fighting whitecaps. Experienced paddlers will find conditions almost boringly manageable. Beginners can venture out, though that morning chill will test your commitment to the sport.
