NWP models
The tables below show the time at which 90% of recent forecast steps were available via the standard API tier (early-access subscribers see them up to 30 minutes earlier). Values are derived from observed dissemination over the last 14 days (4 days for ECMWF ENS, which moved to a new pipeline on 2026-05-19), capped at the dissemination SLA configured in jua-query-v2 and at 1 hour above the worst run observed in the last 3 days, and refreshed periodically.
