Lago di Caldaro has no other spot on this map within 40 km of it. straight-line distance

Lago di Caldaro sits on the South Tyrolean wine road, 1.4 square kilometres of shallow water averaging 3.5m deep, and officially it is not a kite spot. What brings kiters is the Ora, the thermal south wind that runs up from Lake Garda, fills in around 2pm under stable high pressure and builds to Beaufort 4-6 through the late afternoon.
April and May are the window; some spot guides stretch it into a gustier June. The water is about 13°C in April and 19°C by May, so the season starts in full neoprene, and by the time it reaches 28°C in summer the wind has mostly gone quiet.
There is no ordinary beach launch: you are either ferried out by pedal boat or you rig off one of the small wooden landing bridges with a helper, and the shore is shared with a sailing club that runs 100-boat regattas on a lake its own members call tight.
The north wind is rarer, colder and can gust past Beaufort 6. There is no school, no rental and no documented rescue cover, and no rider community to ask, so this is a spring thermal curiosity for a self-sufficient intermediate or advanced rider who is already in the valley.

fills in: Fills in around 2pm under stable high pressure, reaching full strength in the late afternoon.

Typical strength

11-27 (Ora, Beaufort 4-6); occasional stronger northerly gusting to Beaufort 7 (roughly 28-33kt)

Officially this is not a kite spot, though the Ora is reliable in spring under stable high pressure. No kite-specific quality rating or session-count data exists.
March is already in play when the high pressure is stable, and it is the month the first windsurfers turn up. April and May are the two that hold up. June still produces Ora days, gustier ones. Summer goes muggy and close to windless. Autumn brings long flat calms.

The quiver, in words

No local rider report gives a kite size. Against the Beaufort 4-6 the Ora is credited with, a 75-85 kg rider would be looking at roughly 12-14 m at the bottom of that band, 9-10 m through the middle and 7-8 m when it tops out. Indicative, derived from the published wind range rather than measured on this lake.

Direction to shore

The lake runs roughly north-south, about 1.8 km long and under a kilometre across, so the Ora out of the south blows straight up its length and gives you the whole fetch. From the developed west shore that south wind is sideshore.The rare north wind runs the same line in reverse, downwind onto the protected reed belt at the south end, which is the side you do not want to drift into. Derived from the lake's shape rather than a published shore-angle rating.

The model is wrong here

The model reads 3% of days at its best month, which does not sit with the season and the wind strength this record states. The figures are kept and drawn as hatching so no wind colour can be read off them, and the ringed months are the ones riders name.

riders' months

Riders and schools name these months. The model reads lower here, and both are shown rather than averaged.

Modelled from the operational forecast archive at 1.5–7 km (2023-2024), daylight hours only, not a ground station: it resolves thermal, lake and valley winds far better than coarse reanalysis but still tends to understate a strong local thermal. A windy day has at least three consecutive daylight hours at 12 knots or more. The typical daily max and the direction are columns of the table above, month by month. Highlighted months are the riding season from the spot record.

The water

Type

mixed

Standing depth

Not a standing-depth lake. It averages about 3.5 m and reaches 5.6 m at its deepest, so once you are off the shallow margins and the reed shelf at the south end you are out of your depth anywhere on it.

Tides

None — small freshwater alpine-foothill lake, no tidal data applicable.

Temperature

28°C summer

Wetsuit

You want one for the April kite season: the water is about 13°C in April and 19°C by May. It reaches 28°C in high summer, by which point the Ora is weaker and less reliable.

Lake Caldaro (Kalterer See) is 1.4km2, averaging 3.5m deep with a max of 5.6m, and is sold locally as the warmest bathing lake in the Alps.
The shore is shared by a windsurf school and club and by Segelverein Kalterer See, a sailing club founded in 1947 that puts 100+ boats on the water for regattas while calling its own shoreline limited. Kiting on the frozen lake in hard winters is reported but unconfirmed.

No other spot in the atlas sits within reach of this one.

Rescue

Nothing is on call for kiters. Engines are barred from the lake, so there is no safety boat that can come and get you; the only craft on the water are the sailing club's boats and the hired pedal and rowing boats.
The lake is under 2 km at its longest, which is the real safety margin — swimming a kite in is the plan. Emergency calls go to 112.

Launch

No ordinary shore launch is on record. Riders are reportedly taken out onto the lake by pedal boat, or rig from the small wooden landing bridges with a helper; the two accounts have never been reconciled.

Rules & access
2026: no kite-specific rule, permit or designated kite zone has been published, and the lake is not an official kite spot — kiting here is tolerated rather than sanctioned. Engines of any kind are barred from the water, so there are no motorboats on it. The reed belt along the south shore has been protected since 1978 as a nesting and migration site for birds, and the developed access is on the east and west shores only. The bathing season runs May to September, when the lidos, swimmers, pedal boats and rowing boats have the shoreline. A triathlon has been held on the lake every May since 1989 and puts a 1.5 km swim course on the water.

Access rules drift faster than anything else we hold — check locally, and propose an edit if this has changed.

Rider tips

  • Plan the session for the afternoon: the Ora fills in around 2pm and peaks late.
  • Confirm access locally before you drive, because no kite launch, rental point or rescue service is on record.
  • Bring someone to help you launch, and expect to start off a wooden bridge or from a pedal boat.
  • Check the sailing club calendar: regatta days put 100+ boats on 1.4km2 of water.
  • Full neoprene in April, when the lake is around 13°C.
  • Check the sailing club calendar: regatta days put 100+ boats on a lake under 2 km long.
  • Full neoprene in April, when the lake is around 13C.
  • March can already deliver an Ora day if the high pressure is stable, and the water is at its coldest then.
  • Nothing with an engine is allowed on this lake, so plan every session around swimming your own kite in.

Getting there

Airport

Bolzano Airport (BZO) is about 20km away but is a small regional field with limited scheduled service (Sky Alps and a handful of routes); Verona (VRN) and Innsbruck (INN) are the larger commonly-used alternatives for South Tyrol, though neither was confirmed for this specific route.

Route

The lake sits about 20km south of Bolzano along the South Tyrolean wine road (Strada del Vino / Südtiroler Weinstraße).
