Po Valley & Northeast Italy

Vineyards from Lombardy across the Po plain and Alpine foothills to Friuli.

Po Valley humidity, Adriatic influence, Alpine air, and summer storms create large west–east differences.

Climate comparisons use the 1991–2020 combined regional record · updated through Aug 20, 2026.

What stood out in 2009

Less rain often lowers disease pressure, but vines may depend more on stored soil water or irrigation. Frost exposure can vary sharply from one site to the next.

Drier than baseline · Moderate confidence

Growing-season precipitation was 123 mm below the 1991–2020 baseline.

Less rain often lowers disease pressure, but vines may depend more on stored soil water or irrigation.

Spring frost recorded · Low confidence

The regional record had 1 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 Aug 20, 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: 2011 0.665; 2001 0.740; 2007 0.743.

Historical trends, 1991–2025

Growing degree days changed +98.2 GDD per decade. The 95% interval is +75.5 to +120.8 GDD per decade, based on 35 eligible vintages.

How it is measured: Across the March 15–October 31 growing season, each day's mean temperature above 10°C adds to the total; cooler days add zero.

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 August 23, 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 Po Valley & Northeast Italy model uses a March 15–October 31 growing season, base 10°C GDD, and an operational hot-day marker of 35°C.

The historical series uses 4 ERA5 locations, 3 temperature stations, and 5 rain stations. Interpretation confidence: high. Geometry confidence: reviewed-approximate. Rules: veneto-prosecco-catalog-v1-2026-07.
