Wind
Wind on Okanagan Lake
Wind decides more charters here than weather, season or moon phase combined. Two days of hourly forecast, and what each number actually means on a lake shaped like this one.
Reading the wind…
Forecast from Open-Meteo at 10 m above the water, for 49.8164, -119.6229.
Why wind matters more here than almost anywhere
Okanagan Lake is 135 kilometres long, narrow, and hemmed in by steep hills on both sides. That shape does two things. It gives wind a very long run to build waves, and it funnels air along the valley so a moderate regional wind arrives on the water as something stronger and more concentrated.
It also means conditions are extremely local. The north end can be flat while the south end is white-capping, and a bay that is sheltered on a southerly is fully exposed on a northerly. No single forecast number describes the whole lake.
What each band actually feels like
Under about 12 km/h you have glass to a light ripple. Everything is easy, lines behave, and you can hold a precise trolling line. Between 12 and 20 there is some chop; it is still a comfortable day and, if anything, the broken light helps.
From 20 to 30 it gets lumpy. Still fishable, and Geoff regularly does, but you will get wet and boat control takes more work. Above 30 the sensible answer is usually a different day, and that is the call he will make.
A flat calm is not automatically the goal
Anglers new to trolling flies often assume the calmest morning is the best one. Not necessarily. A trophy rainbow feeding near the surface on a dead-flat, bright day is extremely wary, which is exactly why we run the fly so far behind the boat. A bit of surface disturbance breaks up the light and makes those fish noticeably less spooky.
What wind genuinely costs you is comfort and boat control. That is normally the reason a trip moves, not the fishing.
Read the forecast as relative, not absolute
Forecast models smooth terrain, and this valley is anything but smooth. The model consistently under-reads what the funnelling actually produces between the hills. It is why we publish no long-term average wind figure at all: the ten-year reanalysis for this spot claims zero days above 25 km/h in every single month, which is plainly untrue for a lake this size.
So use the hourly numbers to compare one day against another, spot the calm morning window, and then phone. Geoff is looking at the actual water.

Common questions
How much wind is too much to fish Okanagan Lake?
Under about 12 km/h the lake is glass to a light ripple and everything is comfortable. Twenty to thirty is lumpy but fishable if you do not mind getting wet. Over thirty and Geoff will usually move you rather than take you out in it.
That is a guide, not a rule. A 25 km/h wind blowing down the lake behind you is a very different day to the same wind blowing across a bay.
Does wind ruin the fishing?
Not necessarily, and a flat calm is not automatically good. A bit of chop breaks up the light and can make wary fish far less spooky, which matters when you are trolling a fly near the surface.
What wind does ruin is boat control and comfort. That is usually the reason a trip moves, not the fishing.
What happens if the wind comes up after I book?
If conditions are unsafe we do not go out and we reschedule you. Your 25% non-refundable deposit at the time of booking carries over. Geoff makes that call on the morning.
Why does your forecast look calmer than it feels on the water?
Because forecast models smooth terrain, and Okanagan Lake sits in a steep valley that funnels wind. The model tends to under-read what actually happens between the hills. Treat the numbers as relative rather than absolute: use them to compare Tuesday with Thursday, not to decide it will definitely be 14 km/h.
