Weather & wind by day

Per day the most likely wind level and its probability – plus weather, temperature, rain and the strongest wind at the best time of day. The coloured bar in each tile shows how the chances split across the levels.

Wind levels (mean wind or gust):
None below 6 kn · Light 6–10 kn mean wind · Windy from 11 kn mean wind or repeated gusts ≥ 20 kn · Big from 14 kn mean wind or repeated gusts ≥ 25 kn (a single gust doesn't make a wind day)

Wind over time

Hourly – mean and gust wind coloured by strength (local scale), plus the forecast of the key drivers. Two days side by side at full width, otherwise stacked; on mobile each day as rows.

Wind forecast & history

Solid lines are the forecast: mean wind (red) and gusts (anthracite), each with its spread. Once available, the measured values are added in the same colours but dashed. Use the arrows (day/month/year) to page through the days and compare forecast against reality. In knots (kn).

The drivers behind the forecast

The most important inputs of our model for this spot – the same window as the history above. This shows which weather situation is behind the forecast (and, when paging, behind past days).

Thermal drive

The valley wind lives off the sun: it heats the valley and the pressure difference Munich→Innsbruck draws the air up-valley. Both high = strong afternoon valley wind.

Upper wind 850 hPa (speed + direction)

The upper wind at ~1.5 km (850 hPa) can support or overpower the thermals – what matters is the DIRECTION (right compass axis): north supports the valley wind, south blocks it.

Stratification valley↔altitude

Temperature difference between the valley (2 m) and ~1.5 km altitude (850 hPa). Large = much warmer below than above: warm air can rise, unstable – good for thermals. Small or negative = cold below, warm above (inversion): a stable lid that damps the thermals.

Foehn

South foehn arises when air pressure south of the Alps is clearly higher than north of them. Shown is the model pressure difference Bolzano−Innsbruck. From about +3 hPa (dashed line) the pressure difference is enough for foehn – whether it actually breaks through to the valley also depends on upper wind and dryness. On real foehn days the daily peak typically reaches about +5 hPa. Between 0 and +3 hPa the southern pressure is usually too weak for foehn; below zero (blue) the higher pressure lies to the north: northerly situation, no foehn. How much of it reaches the lake depends on the spot: at the Kochelsee foehn is one of the main winds, at the Walchensee it breaks through to the water less often – there the wind chance only rises noticeably from about +5 hPa. Other foehn charts reduce pressure to sea level differently and therefore read several hPa higher – the threshold applies to this scale only.
