Wachau

Danube vineyards from Spitz through Weißenkirchen and Dürnstein to the western edge of Krems.

A narrow river valley and steep slopes create sharp day–night temperature shifts. Spring frost, summer heat and rain during the long autumn harvest are the main weather signals.

Climate comparisons use the 1991–2020 combined regional record · updated through Sep 13, 2026.

What stood out in 2014

Frequent rain can mean more canopy growth and more disease pressure. Rain close to harvest can raise rot pressure and shorten the picking window. Frost exposure can vary sharply from one site to the next.

Wetter than baseline · Moderate confidence

Growing-season precipitation was 192 mm above the 1991–2020 baseline.

Frequent rain can mean more canopy growth and more disease pressure.

More harvest rain than usual · High confidence

Harvest-window precipitation totaled 222 mm, +64 mm versus baseline.

Rain close to harvest can raise rot pressure and shorten the picking window.

Spring frost recorded · Low confidence

The regional record had 8 spring day(s) at or below 0°C.

Frost exposure can vary sharply from one site to the next.

Calendar data and method

Monthly values are weighted across every configured regional sample using stored Google ARCO ERA5 daily reanalysis. “Typical” is the mean monthly total across 30 baseline seasons. GDD is counted only inside the configured growing window; freezing days are counted only inside the frost-watch window; rainfall covers every displayed calendar day.

Selected-vintage coverage is 100%. Source rows were last retrieved Sep 13, 2026.

How similar years are calculated

Method analog-v1-2026-07 standardizes six weather measures across 34 complete ARCO ERA5 comparison years, then measures the distance between them. The calculation runs when the page is requested.

Measures used: Growing-season mean temperature (20%); Growing degree days (15%); Hot-day count (15%); Growing-season precipitation (20%); Harvest precipitation (20%); Spring frost exposure (10%).

Calculated distances: 2020 0.539; 2016 0.648; 2002 0.672.

Observed record

Historical trends, 1991–2025

Growing degree days changed +86.4 GDD per decade. The 95% interval is +56.7 to +116.2 GDD per decade, based on 35 eligible vintages.

How it is measured: Across the April 1–November 15 growing season, each day's mean temperature above 10°C adds to the total; cooler days add zero.

How pathways are combined

For each period and percentile, Weather & Vines takes 70% of the SSP2-4.5 value, 15% of the SSP1-2.6 value, and 15% of the SSP3-7.0 value. Each pathway contains the same 25 models. The weights are an editorial view of the current trajectory, not scenario probabilities.

Data and methods

Show data sources and model assumptions

Current model conditions and the 10-day outlook use the 00 UTC deterministic ECMWF IFS 0.25° public forecast retrieved directly with Herbie. Historical temperature and rain combine qualifying GHCN-D stations with ERA5 by geographic area; a missing station day uses the nearest ERA5 value for that station's area. Climate comparisons use 1991–2020.

Forecast comparisons use the 1991–2020 combined regional daily record. Daily high and low averages use the matching date; rainfall and GDD sum the same calendar dates as the forecast period.

This service is based on data and products of the European Centre for Medium-Range Weather Forecasts (ECMWF). Weather & Vines subsets, converts, and regionally weights the forecast fields. ECMWF data are published under CC BY 4.0. ECMWF accepts no liability for errors, omissions, availability, loss, or damage arising from their use.

Climate projections use NASA NEX-GDDP-CMIP6 v2.0, accessed September 20, 2026, with 25 models. Weather & Vines subsets and aggregates the source fields. Source files and derived projection data are under CC BY-SA 4.0; the full roster and limitations are listed in the climate atlas methods.

The Wachau model uses a April 1–November 15 growing season, base 10°C GDD, and an operational hot-day marker of 32°C.
