How extreme does Busselton's weather get?

The hottest, coldest, wettest and snowiest days Busselton has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Cowaramup station 32 km away. Updated through May 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Busselton has recorded — each shown against what a normal day that time of year looks like.

🌧️ Most rain in one day

3.34 in Jul 11, 1980

About 44% of a typical July's rain in a single day (Busselton averages roughly 7.6 in across the month).

The three most extreme on record

1 3.34 in Jul 11, 1980

2 3.05 in Aug 8, 2021

3 2.99 in Jul 27, 2025

In plain terms

A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
