Forecast Accuracy
“How far off were we?” — Explore hourly error vs. lead time, plus a clean daily Forecast vs Observed comparison.
What am I looking at?
For the selected city and day(s), we compare hourly forecasts to what actually happened. The line shows error vs. “hours ahead” (how far in advance the forecast was made). Toggle “All days” to see multiple days overlaid (click chips to isolate).
Data flow
Batch DAGs compute MAE, RMSE and Bias by horizon and export
docs/data/metrics_history.csv (and metrics_latest.csv) which power this page.
dbt builds staging + marts, runs tests, and we publish dbt docs.

Forecast vs Observed — Daily
Hourly forecasts are aggregated per day (mean for temperature & wind, sum for precipitation), then compared to observed.
