Welcome to what looks like a genuinely excellent day on Jack Lake. We’re looking at a high of 74°F this afternoon with a morning low of 62°F—classic late spring or early fall paddling weather that Wisconsin does so well. Early risers will encounter calm 9 mph southwest winds and partly sunny skies to kick things off.

Paddling Window: 7AM-7PM Breakdown

Here’s where today gets interesting. Temperatures climb steadily from 62°F at 7am through 67°F by 9am, then push into the low 70s by late morning. The sweet spot? That 1pm to 4pm window when you’ll hit peak temps of 73-74°F under mostly sunny to sunny skies. Winds pick up from 9 mph in the early morning to a consistent 12 mph from 10am through 4pm, settling back to 10 mph by 5pm. That westerly wind means you’ll want to plan your route accordingly—head into it early while you’re fresh. The humidity story is equally compelling: you’ll start in a thick 97% humidity blanket that burns off dramatically to a comfortable 38-40% by mid-afternoon.

Through the Day

Early morning paddlers at 7am face that soupy 97% humidity and partly sunny skies at 62°F—atmospheric but damp. By 10am, you’re at 69°F with winds building to 12 mph from the west as cloud cover increases to mostly cloudy. The real magic happens after noon when skies clear to mostly sunny, then fully sunny by 4pm. Late afternoon from 5pm-7pm offers the gentlest conditions: temperatures easing from 72°F down to 65°F, winds dropping to 7-10 mph, and crystal clear skies for that golden hour paddle.
