What stood out in 2026

Warm weather can speed ripening and leave grapes with less acidity. Less rain often lowers disease pressure, but vines may depend more on stored soil water or irrigation.

Warmer growing season · High confidence

Mean growing-season temperature was +1.6°C versus the 1991–2020 baseline.

Warm weather can speed ripening and leave grapes with less acidity.

Drier than baseline · Moderate confidence

Growing-season precipitation was 148 mm below the 1991–2020 baseline.

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

Observed record

Historical trends, 1991–2025

Growing degree days changed +93.8 GDD per decade. The 95% interval is +58.3 to +129.3 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.

Model ensemble

Projected climate through 2075

Temperature changes are relative to each model’s 1991–2020 baseline. The table combines all three pathways, weighted 70% to SSP2-4.5 and 15% each to SSP1-2.6 and SSP3-7.0.

Scroll horizontally to compare all columns.

Period	Weighted median	Weighted central 80%	Models per pathway
2021-2040	+1.2°C	+0.9 to +1.6°C	25
2041-2060	+1.8°C	+1.2 to +2.6°C	25
2061-2075	+2.3°C	+1.8 to +3.5°C	25

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 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 Abruzzo model uses a March 15–October 31 growing season, base 10°C GDD, and an operational hot-day marker of 35°C.
