Transparency & decision layer for CurrentWeather.info

Weather data,
sourced and verified.

CurrentWeather.info shows you the forecast. RealWeather shows you why—every value labeled by provenance, every fallback visible. No silent smoothing or hidden averaging—just per-field selection with provenance tags.

Provenance labels

Every value carries one of three per-field labels. A Hybrid badge may appear when a view mixes sources; per-field labels remain the source of truth:

obs
Observed Direct measurement from station observations (METAR/ASOS/AWOS when available). Used when fresh and passes validation.
model
Model Open-Meteo forecast/analysis. Used for future periods, or as fallback when an obs field is missing, stale, or fails validation.
derived
Derived Calculated from whichever inputs won (obs/model, sometimes a hybrid mix)—feels-like, dew point labels, risk indices.

THE DECISION PIPELINE

Every field runs this gauntlet. Observations win when fresh and sane. Models fill only the failed fields (missing/stale/invalid). Derived values get computed from the winners. Everything gets labeled—no exceptions.

Methodology

Freshness windows, validation bounds, fallback logic. The complete decision rules—documented so you can audit them.
