Calculated from quality-unflagged daily records in the imported 20260812 snapshot. Rainfall totals enter a monthly average only where at least 90% of that month's daily observations are present; the final column is the denominator. Temperature values are means of the valid daily observations shown.

Evidence boundary

Evidence found19,547 quality-accepted temperature and rainfall observations for station ASN00086038 in the fixed 1991-2020 window; 0 observations carrying NOAA quality flags were excluded.
Source coverageNOAA/NCEI GHCN-Daily station observations, imported to R2 as snapshot 20260812 on 13 Aug 2026. This page uses one selected station for each Australian capital and exposes its station ID, distance, period and denominators.
What this meansThe page supports a reproducible comparison of observed historical station context around the eight capitals.
What this does not meanIt is not live weather, a forecast, an official climate normal, a future climate projection, a flood or bushfire assessment, a parcel condition, valuation evidence, or planning advice.

Unavailable or excluded layers

Live weather and forecastsNot checked / not published. The imported feed is historical station evidence; no current-condition or forecast feed is used.
Copernicus bulk climate layersNot published. The unified importer records these as credentialed and scope-gated; no raster or projection is invented here.
Environment Agency flood and catchment feedsNot applicable. Those approved importer feeds cover England, not Australia, so they are excluded from this product.
Parcel flood, bushfire and planning controlsNot supplied by this page. Check the applicable state and council mapping and obtain professional advice for a specific site.
