Italy · Detailed regional profile

Tuscany

A 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 1996

Cool weather can slow ripening and help grapes retain acidity. Frequent rain can mean more canopy growth and more disease pressure. Rain close to harvest can raise rot pressure and shorten the picking window.

Cooler growing season · High confidence

Mean growing-season temperature was -1.2°C versus the 1991–2020 baseline.

Cool weather can slow ripening and help grapes retain acidity.

Wetter than baseline · Moderate confidence

Growing-season precipitation was 124 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 323 mm, +92 mm versus baseline.

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

Spring freeze recorded · Moderate confidence

The regional record had 1 spring day(s) at or below -2°C.

A freeze after budbreak can damage new growth and reduce the crop.

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: 1993 0.859; 1992 1.049; 1995 1.117.

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.

Region outline: Istituto nazionale di statistica (Istat), 2026; reprojected and simplified by Weather & Vines; CC BY 4.0. This is a statistical administrative boundary, not a wine-denomination boundary.

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.
