BLEND‑NQ

ReefNav’s own wind forecast. Six global models — ECMWF, ECMWF AIFS, GFS, ICON, GEM and UKMO — blended rather than any single one, then bias‑corrected against a nearby weather station’s own last 40 days wherever one is close enough to allow it.

The range beside the wind is the span the true value falls inside about 80% of the time. It is measured from real errors, not estimated.
