This week on Castle Rock
Over the next 7 days on Castle Rock Lake, the windiest stretch looks like Tuesday, with gusts to about 17 kt. Friday is the calmest day in the outlook, topping out near 4 kt.
Tuesday is the pick for sailing, and Thursday looks best for kayaks and paddleboards. Mornings are usually calmer than afternoons, so check the hourly strip for the exact window.
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.
Castle Rock Lake is large enough for wind to build real waves. When the forecast direction lines up with the long open stretches of the lake, expect bigger chop than the wind speed alone suggests, and plan routes that keep you near a sheltered shore on the way back.
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 Castle Rock Lake 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.
