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.

1949Each stripe is one year’s mean temperature against the 68-year average. Warmest: 2025. Coolest: 1992.2025

Station distance: 2.3 km from the place centre
Climate period: 1991–2020
Minimum month coverage: 22 usable years

Sea temperature: NOAA OISST v2.1 1991–2020 monthly climatology, nearest open water 18 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 INVERCARGILL AIRPOR is what differs
