Has the climate in Warrnambool changed?

Warrnambool has warmed about 0.7°F since 1999.

About 0.3°F per decade, measured from Warrnambool's official daily weather records, 1999–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Warrnambool's climate has warmed more slowly than most other cities in Australia.

What has actually changed

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.

In day-to-day terms, that long-term shift shows up as about 2 more freezing nights a year and about 2 more days above 90°F compared with the 1970s.

When in the year the change shows up

How much warmer each month is now than in the 1970s. Useful if you garden or care about a particular season — otherwise the headline above already has the answer.

February has cooled the most — about 2.8°F. The warming runs across the whole year, not just one season.

Methodology & sources

Temperature — 1991–2020 normals computed from 22 years of daily observations at Warrnambool Airport Ndb, a weather station, about 11 km from the city centre. The underlying daily records come from NOAA's global station network.
