Seasonal / forecast estimateComfort comes first
Rated for sustained Sea-Doo cruising. Around 0.2 m–0.3 m waves can make a long ride tiring, even when a short outing is manageable.
Cold water and chop
Rough water over 9 C water is the combination that hurts people on this lake. The chop raises your odds of going in, and the temperature removes your ability to do anything about it once you are there.
Cold ride
It is 7 C on shore but only about -9 C once you are on the ski and wet. That is 16 degrees of wind chill and spray you cannot see from the parking lot. This is genuinely dangerous to be exposed to. Full drysuit or do not go.
Cold water
Water is 9 C. That is cold shock territory: an unexpected swim causes involuntary gasping within seconds and useful hand function is gone in ten to fifteen minutes. A wetsuit and a worn PFD are not optional today.
This estimate is for this location. Exposed water along your route and the trip home may be rougher.
How to read the rating
85–100 Excellent · 70–84 Good · 50–69 Marginal · 30–49 Poor · below 30 Dangerous. Hazards can lower the verdict further.

Gusty
Gusts to 22 kt, which is 11 kt above the steady wind. Squally, uneven air like this makes handling unpredictable and kicks up chop in bursts.
Long-distance comfort
Waves around 0.5 m (1.6 ft) can mean repeated impacts, reduced speed and fatigue on a Sea-Doo. A short local outing may be manageable, but this is not a comfortable long-distance recommendation. The short 3.6 second spacing lowers the comfort rating further.
Wave height
Chop at 0.5 m (1.6 ft), with larger sets around 0.7 m. Expect bumps and a slower ride.
Wave shape
Short 3.6 second period, so this is stacked steep chop rather than a rolling swell. It will feel considerably worse than the same height on the ocean.
Sheltered
The wind only has 0 km of open water to work with before it reaches you, because the shoreline upwind is in the way. That is why it is 0.5 m here while the open lake is far rougher in the same wind.
Wind
11 kt from the WNW. Comfortable working breeze.
Full explanation of today's conditions
Expect a beating. The water runs to 0.5 m (1.6 ft) and it will be relentless rather than occasional. You would spend the whole time working and none of it enjoying yourself. It will feel brutal out there, around -11 C on the ski even though the shore reads 8 C. That gap is wind chill plus spray, and it is the thing that ends rides early. This is genuinely dangerous to be exposed to. Full drysuit or do not go. The water is 9 C. Bracing does not cover it, and an unplanned swim is a serious problem, not a laugh.
For sea-doo / personal watercraft today, this is a poor day, scoring 37 out of 100 across daylight hours. Waves range from 0.4 m to 0.5 m (1.6 ft), with wind from the W gusting to 26 kt at its worst. Daylight runs 8:38 AM to 6:42 PM. There is no window today that clears the bar for going out. The calmest stretch is around 12 AM at 0.3 m, and even that is not enough to make the day worth it. What is working against you, at the worst of it: Rough water over 9 C water is the combination that hurts people on this lake. The chop raises your odds of going in, and the temperature removes your ability to do anything about it once you are there. It is 5 C on shore but only about -10 C once you are on the ski and wet. That is 15 degrees of wind chill and spray you cannot see from the parking lot. This is genuinely dangerous to be exposed to. Full drysuit or do not go. Water is 9 C. That is cold shock territory: an unexpected swim causes involuntary gasping within seconds and useful hand function is gone in ten to fifteen minutes. A wetsuit and a worn PFD are not optional today. Worth watching: Gusts to 25 kt, which is 18 kt above the steady wind. Squally, uneven air like this makes handling unpredictable and kicks up chop in bursts. Waves around 0.5 m (1.5 ft) can mean repeated impacts, reduced speed and fatigue on a Sea-Doo. A short local outing may be manageable, but this is not a comfortable long-distance recommendation. The short 3.9 second spacing lowers the comfort rating further. In your favour, at the best of it: The wind only has 0 km of open water to work with before it reaches you, because the shoreline upwind is in the way. That is why it is 0.4 m here while the open lake is far rougher in the same wind. 10 kt from the WNW. Comfortable working breeze.

Cool on the water
The shore says 13 C, but moving across the water it will feel more like 8 C. Nice enough in the sun, nippy the moment you stop. Wetsuit or a proper drysuit top. A hoodie will be soaked and useless in ten minutes.

Even in the best forecast hour, 0.2 m (0.5 ft) waves can mean repeated bumps and a slower, tiring long-distance ride. A short outing and a long crossing are different decisions. It will feel cold out there, around 8 C on the ski even though the shore reads 13 C. You will be fine while you are moving and cold the second you stop. Wetsuit or a proper drysuit top. A hoodie will be soaked and useless in ten minutes. The water is 9 C. Bracing does not cover it, and an unplanned swim is a serious problem, not a laugh. Aim for 3 PM to 4 PM. It goes downhill after that, so do not be the last one off the water.
For sea-doo / personal watercraft on Sunday, Nov 1, this is a marginal day, scoring 58 out of 100 across daylight hours. Waves range from 0.1 m to 0.2 m (0.8 ft), with wind from the SSW gusting to 7 kt at its worst. Daylight runs 8:43 AM to 6:37 PM. The best window is 3:00 PM to 4:00 PM (1 hour), and the single best hour is around 3 PM. In that window the water runs to about 0.2 m with wind to 2 kt. After 4:00 PM the best you will get is marginal, with the water running toward 0.2 m, so plan to be back on the trailer by then. Earlier in the day it only reaches marginal, so there is no advantage to launching at first light. What is working against you, at the worst of it: It is 13 C on shore but only about 8 C once you are on the ski and wet. That is 5 degrees of wind chill and spray you cannot see from the parking lot. Wetsuit or a proper drysuit top. A hoodie will be soaked and useless in ten minutes. Water is 9 C. That is cold shock territory: an unexpected swim causes involuntary gasping within seconds and useful hand function is gone in ten to fifteen minutes. A wetsuit and a worn PFD are not optional today. Worth watching: Waves around 0.2 m (0.8 ft) can mean repeated impacts, reduced speed and fatigue on a Sea-Doo.
