Data sources
Every number and every pixel on betterbom comes from somewhere. Here's the receipt.
Last updated: 3 June 2026
We believe weather data should be auditable. The live numbers you see on betterbom — forecasts, radar and air quality — come from the providers listed below. The "source" badge next to a value tells you which provider it came from and the time it was issued.
Active sources

|---|---|---|
| Open-Meteo (forecast) | Daily and hourly forecasts (multi-model best match, which includes BOM ACCESS-G, ECMWF, GFS and ICON among its inputs) | CC BY 4.0 with commercial use permitted |
| Open-Meteo Air Quality | Air-quality index and pollutant concentrations (PM2.5, PM10, ozone, NO₂, SO₂, CO) | CC BY 4.0 with commercial use permitted |

Bureau of Meteorology attribution
Where data is sourced from the Bureau of Meteorology, we attribute it as:

How freshness is communicated
Live values on betterbom carry a timestamp and a freshness badge that reads "Live" when the data is current, or "N min ago" once it has aged.
If an upstream provider is temporarily unreachable when a page renders, betterbom may fall back to a small set of neutral placeholder values so the page still loads. In that case the source is labelled "… unavailable" (for example "Open-Meteo unavailable") rather than shown as a live reading. We are still expanding this coverage — a prominent site-wide "Stale" / "Source temporarily unavailable" banner is on the roadmap, and until it ships you should treat any value carrying an "unavailable" source label as indicative only and verify time-critical information directly with the Bureau of Meteorology.
