Today’s Conditions at Jack Lake

We’re looking at a genuine spring day here on Jack Lake, Wisconsin with temperatures ranging from a cool 50°F at dawn to a pleasant high of 69°F by mid-afternoon. The morning kicks off with gentle 7 mph winds out of the south-southeast, building as the day progresses—so plan your paddle accordingly.

Paddling Window: 7AM-7PM Breakdown

Early birds will find 50°F temperatures at 7am under mostly cloudy skies, with winds starting mellow at 7-8 mph from the SSE. The real transformation happens between 9am and 11am as temperatures climb from 53°F to 61°F and skies shift to partly sunny. By noon, you’re sitting at 65°F with winds picking up to 13 mph from the south—noticeable but manageable. The sweet spot? That 11am to 1pm window delivers the best combination of warming temps (61-67°F) and building sunshine. The afternoon peak hits around 3pm when you’ll see the day’s high of 69°F, though winds will also reach their peak at 14 mph. If you’re wind-sensitive, get on the water before 11am when conditions are calmer.

Through the Day

The morning hours from 7-9am offer cooler, cloudier conditions with humidity hanging around 80-83%—layer up and expect some dampness in the air. Midday brings the transformation: by noon temperatures jump to 65°F with humidity dropping to a comfortable 52%. The 2-4pm stretch is the warmest at 68-69°F with mostly sunny skies, but those south winds will be steady at 13-14 mph, creating some chop on the water. Late afternoon from 5-7pm sees temperatures gently declining from 67°F to 61°F as clouds return and winds ease back to 10-12 mph.

Why Today Works

This is a solid day for intermediate paddlers who don’t mind working against a bit of wind. With sustained south winds averaging 11 mph throughout the day and peaking at 14 mph in the afternoon, beginners should stick to the calmer morning hours. The 19-degree temperature swing from morning to afternoon means layering is essential—bring something you can shed.
