Today at Jack Lake, we’re looking at a steamy, stormy day with temperatures climbing from 74°F in the early morning to a high of 84°F by mid-afternoon. Thunderstorms are likely throughout the entire paddling window, and winds are holding steady at 5 mph from shifting directions. This is a day that demands respect and caution.

Paddling Window: 7AM-7PM Analysis

Let’s be completely honest here: thunderstorms are forecast for every single hour of our paddling window today. The morning kicks off at 7am with 74°F and 97% humidity—you’ll feel like you’re paddling through soup. By 10am, temps jump to 81°F as the humidity drops slightly to 82%. The peak heat arrives between 2pm and 5pm when we hit 84°F. Winds remain remarkably consistent at 5 mph all day, shifting between southeast and east. If there’s any window at all, the early morning hours before 9am offer slightly cooler temps, but that thunderstorm threat never leaves.

Through the Day

Early morning from 7-9am sees temperatures rising from 74°F to 77°F with that oppressive 94-97% humidity. Midday brings the real heat—81°F at 10am climbing to 83°F by noon—with those 5 mph winds offering minimal relief. Late afternoon holds steady in the 82-84°F range through 7pm. The wind direction rotates between southeast and east throughout the day, but the speed stays locked at that gentle 5 mph, meaning the water will be glassy when storms aren’t rolling through.

Why Today Works (Or Doesn’t)

Today is honestly best suited for experienced paddlers who understand lightning safety and are prepared to get off the water immediately when storms approach. With 5 mph winds and warm water temps, the paddling itself would be easy—it’s the weather that’s the problem. If you’re visiting Jack Lake hoping for a peaceful kayak rental experience, you might want to check the radar obsessively.
