When is it jumpable at Parac. Etruria (Arezzo)?

The Parac. Etruria jumpability score is green (≥70/100) when surface wind stays below 8 m/s, gusts below 10 m/s, cloud base sits above tandem exit altitude (Parac. Etruria operates at typical operational altitudes of ENAC Italian dropzones), and no storms are incoming in the next 2 hours. Open the dropzone page to see the usable window hour by hour for the next 7 days.

Which weather model do you use for Parac. Etruria?

The Parac. Etruria primary forecast (temperature, cloud, visibility, CAPE, wind at 10/80/120 m altitudes) comes from the best-match model auto-selected for the area — typically ICON-EU (DWD). In parallel we query all 4 models — ICON-EU + ECMWF IFS + AROME France HD + GFS — on wind, gust and precipitation, and compute σ across them to estimate hour-by-hour forecast confidence.

Can I book a tandem in Arezzo based on the forecast alone?

The forecast is a pre-decision tool (is it worth driving?) and never replaces the on-site jumpmaster's briefing. Even on a green score, the final go/no-go is taken by the dropzone using the actual ground wind reading. To book, contact Parac. Etruria directly from the school page.

⚠️ The forecast never replaces the jumpmaster's briefing. ICON-EU + AROME + ECMWF + GFS are high-resolution models, but on complex orography (Alps, Adriatic coast) they may miss reality by a factor. Always verify with the dropzone before driving over.

Legend · jumpability score

70+

Jumpable 70–100

Comfortable operating conditions, including for students and tandems.

40+

Borderline 40–69

On the edge — tight wind or cloud. Often no students; sport jumpers with caution.

No-go 0–39

Extreme wind, gusts, storms, cloud below exit, or visibility below threshold.

The score combines surface wind, gusts, upper-level wind, cloud vs DZ exit altitude, CAPE (storms), rain in the next 2 hours and visibility. Operational thresholds, not meteorological. How the models work ↗
