The Ora is Lake Garda’s southerly wind: it switches on once the sun has heated the plain, runs up the lake through the afternoon and fades at sunset. It is the most reliable wind on the Benaco, the one that fills the beaches with sails — and the one almost everybody learns on.
The Ora is a thermal breeze, born from a temperature difference. Through the middle of the day the plain to the south warms far more than the mountains to the north and than the lake water. Warm air rises, and air is drawn in from the lake surface to replace it: a flow forms that runs up the basin from south to north.
It is the opposite mechanism to the Pelèr — there, cold air falling under gravity; here, air pulled in by heat. That is why the two winds have opposite schedules and never coexist: they take turns.
The Ora needs the sun to have worked for a few hours. It usually starts to be felt around midday, builds through the early afternoon, holds into the evening and dies with the sun.
The build-up is gradual, and that is its best quality: you can get on the water while it is still light and find it fully powered half an hour later, instead of taking twenty knots in the face from the first minute. For someone learning, that is the difference between a good day and a bad one.
The exact onset time is not the same every day or at every spot: it depends on how much, and how fast, the plain heats up. It is one of the values this app learns from measured history, spot by spot.
The same geometry as the Pelèr, reversed. The flow runs up the lake from the south, where the basin is wide, towards the north, where it narrows between the mountains: the air is squeezed into a smaller and smaller section and accelerates.
That is why the Ora is stronger and steadier in the northern lake — Torbole, Riva, Campagnola, Campione — while in the south it stays lighter. It is also why the northern lake gets two good winds a day and the southern basin often only one.
Being thermal, the Ora depends on the sun, and there are conditions where it simply does not switch on, or switches on badly:
The difference between the two regimes is visible to the naked eye in the station data, and it is why every spot in this app has a «when it blows» section built on its own measurements rather than on a general description.
At a north-facing station in the upper lake the daily peak falls in the early morning hours, with wind from the north. At another station a few kilometres away but differently exposed, the peak falls in the early afternoon with wind from the south. Same lake, same day, two opposite answers to «what time should I go out».
These are one season’s statistics, not a climatology: our archive starts in June 2026. When we have a full year we will also be able to say which months are best — which today would simply be invented.
The Ora is the wind people learn on at Garda: it builds gradually, it is warmer than the Pelèr, and it is steadier — a smaller gap between average and gust, which is what really matters while you are still learning to stand up.
The most useful practical advice: get on the water just after the Ora has started and while it is still building, and come in before the peak. The first hour and a half is the best window for a beginner; after that it becomes a wind for fit, practised people, especially in the northern lake.
Usually around midday, building through the early afternoon. The exact time changes day to day and spot to spot, because it depends on how much the plain has heated: that is why the useful window should be read on the spot page, not from a general rule.
The Ora, without question. It builds gradually, it is warmer and it is steadier. The Pelèr is strong from the start, cold and choppy: beautiful, but not where first flights happen.
Almost always one of four reasons: overcast sky, too strong a northerly flow, instability and storms disorganising the thermal, or a Pelèr that held on too long. If the sky is closed by mid-morning, the afternoon Ora is at risk.
No. Going north the basin narrows and the wind accelerates: in the upper lake the Ora is clearly stronger and steadier than in the south. The onset time changes from spot to spot as well.
