Today at Jack Lake, Wisconsin, we’re looking at a stunning sunny day with a high of 68°F and a crisp morning low of 48°F. Early birds will find calm waters with winds starting at just 5 mph from the northwest—absolutely ideal for getting out before the breeze picks up.

Paddling Window: 7AM-7PM

The hourly breakdown tells a clear story today. At 7am, you’re looking at 48°F with 93% humidity and gentle 5 mph winds—layer up, but conditions are glassy. By 10am, temperatures climb to 59°F with winds building to 8 mph. The real change happens midday: by noon, we hit 65°F with 13 mph winds from the WNW, and that breeze continues strengthening through the afternoon. Peak wind arrives between 3pm and 4pm at 16 mph, which will create some chop on Jack Lake. Your best sub-window? Without question, 7am to 11am offers the calmest water and warming temperatures before winds become a factor.

Through the Day

Early morning paddlers enjoy that magical progression from 48°F at 7am to 62°F by 11am, with winds gradually increasing from 5 mph to 10 mph—still very manageable. The midday hours from noon to 3pm see temps peak at 68°F, but winds also peak at 14-16 mph, making paddleboarding more challenging and kayaking more spirited. Late afternoon from 5pm to 7pm brings temps back down to 58-65°F as winds ease to 10-15 mph. The humidity drops significantly throughout the day, from 93% down to 32%, making that afternoon sun feel quite pleasant despite the breeze.

Why Today Works

Today is perfect for kayakers of all skill levels who get out early, and for experienced paddleboarders comfortable with afternoon chop averaging 11 mph winds overall. If you’re new to paddleboarding, stick to the morning hours when winds hover around 5-7 mph. Experienced paddlers looking for a little workout will love the afternoon conditions.
