A warm and dry day reaches 20°C with under 1 mm of rain; a wet day gets 1 mm or more; a washout gets 10 mm or more. The week column is the share of seven-day stretches in that month, across the station’s whole daily record, that contained three or more wet days — the odds a week-long trip is rained on repeatedly, counted rather than modelled. The last column is the 10th to 90th percentile of that month’s daytime average across individual years: a narrow band means the average is what you will get, a wide one means the average is a midpoint between years that felt quite different.

1976Each stripe is one year’s mean temperature against the 33-year average. Warmest: 1998. Coolest: 1976.2011

Nearby, measured,
and named.

Place identity: GeoNames 2171845
NOAA station: ASN00061242 · CESSNOCK (NULKABA)
Station distance: 2.6 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 19 usable years
Daylight: Calculated from latitude -32.83°, mid-month, sunrise to sunset including refraction. Not a station measurement.
Sea temperature: NOAA OISST v2.1 1991–2020 monthly climatology, nearest open water 41 km from the place centre. A sheltered bay can run warmer than the open sea it is measured from.
Important limit: Historical climate is not a forecast. Nearby stations can miss mountains, coasts, and local microclimates.

These places read the same station, so their numbers are identical — distance from CESSNOCK (NULKABA) is what differs
