⚠️ 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.
0+
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 ↗
