Jack Lake is shaping up for a dynamic day on the water, with temperatures climbing from a cool 58°F at dawn to a pleasant high of 71°F by mid-afternoon. Southwest winds are already moving at 12 mph as the day begins, and they’ll have plenty to say about your paddling experience throughout the hours ahead.

Paddling Window: 7AM-7PM Breakdown

Early birds hitting the water at 7am will find cloudy skies, 58°F temps, and 12 mph southwest winds—manageable but brisk. By 9am, conditions shift as winds pick up to 15 mph from the WSW, and temperatures reach 61°F. The most challenging stretch comes between 11am and 2pm when winds hold steady at 16-17 mph from the west—this is the gusty heart of the day. Your best sub-window? Late afternoon from 5pm onward when winds calm to 12 mph at 5pm, dropping further to just 9 mph by 6pm and 7 mph by 7pm. That’s when Jack Lake becomes friendliest for paddlers who prefer calmer conditions.

Through the Day

The morning hours from 7am to 10am see temperatures climbing steadily—58°F to 64°F—while clouds gradually break up from fully cloudy to mostly cloudy. Humidity sits at a saturated 100% until mid-morning, so expect that damp, dewy feel. Midday brings the warmest and windiest conditions together: 67°F at noon with 17 mph westerly winds making paddleboards more challenging than kayaks. The afternoon transformation is welcome—by 3pm winds ease to 15 mph, and by 5pm you’re looking at 69°F with just 12 mph of breeze. The evening wrap-up offers the calmest paddle of the day with temps settling to 64°F under mostly clear skies.

Why Today Works

This is a day built for experienced paddlers during peak hours and everyone else during the bookend periods. If you’re comfortable in 14-17 mph sustained winds, the midday sunshine and 70°F temperatures are yours to enjoy. If you prefer gentler conditions, arrive after 5pm when winds drop to 9-12 mph and the lake smooths out considerably.
