Italy · Detailed regional profile
Tuscany
Sign in to followA varied central Italian region best known for Sangiovese, with Bordeaux varieties also grown near the coast.
Elevation and distance from the sea separate the warmer, drier interior from the coast. Autumn rain adds another important difference.
Climate comparisons use the 1991–2020 combined regional record · updated through Aug 20, 2026.

What stood out in 2023
Warm weather can speed ripening and leave grapes with less acidity. Frost exposure can vary sharply from one site to the next.
Warmer growing season · High confidence
Mean growing-season temperature was +1.5°C versus the 1991–2020 baseline.
Warm weather can speed ripening and leave grapes with less acidity.
Spring frost recorded · Low confidence
The regional record had 1 spring day(s) at or below 0°C.

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: 2003 0.821; 2022 0.826; 2018 0.835.

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 |

| 2061-2075 | +2.3°C | +1.7 to +3.4°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 Tuscany model uses a April 1–October 31 growing season, base 10°C GDD, and an operational hot-day marker of 35°C.
The historical series uses 3 ERA5 locations, 0 temperature stations, and 1 rain station. Temperature is ERA5-only. Interpretation confidence: high. Geometry confidence: authoritative. Rules: tuscany-v4-2026-08.
