This week on Saint Catherine

Over the next 7 days on Lake Saint Catherine, the windiest stretch looks like Friday, with gusts to about 18 kt. Sunday is the calmest day in the outlook, topping out near 8 kt.

Monday is the pick for sailing, and Monday looks best for kayaks and paddleboards. Mornings are usually calmer than afternoons, so check the hourly strip for the exact window.

Thunderstorms are in the forecast for Saturday, Sunday. Plan to be off the water before the first rumble; lightning can strike miles ahead of a storm.

Reading a lake wind forecast

Sustained wind is the average over a couple of minutes; gusts are the short peaks. On inland water the gap between the two matters as much as the average. A steady 12 kt is a pleasant sail, while 8 kt gusting 20 kt knocks small boats flat and tires out paddlers.

On a lake the size of Saint Catherine, waves stay modest, but nearby hills, trees and buildings bend the wind. Expect shifts and puffs, especially close to shore, and treat the forecast speed as an average across open water.

The National Weather Service forecast covers a 2.5 km grid, so local effects like a sea breeze off a big lake, a cold front or afternoon thunderstorms can arrive earlier or stronger than shown. Check the forecast again on the morning you go, and keep an eye on small craft advisories.

Where does the Lake Saint Catherine wind forecast come from?

From the National Weather Service gridded forecast for the 2.5 km cell over the lake. It is the same forecast local NWS offices use, updated several times a day. We convert wind to knots and add our own go or no-go call for each activity.

What wind is too strong for a kayak or paddleboard?

We flag paddling as risky once sustained wind passes about 8 kt or gusts pass 12 kt, and advise staying ashore above 12 kt sustained or 18 kt gusts. Offshore wind is the most dangerous because it pushes you away from the launch.
