The hottest, coldest, wettest and snowiest days Byron Bay has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 24 years of daily weather observations (2002–present), from the Byron Bay (Cape Byron Aws) station 3 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 Byron Bay

In plain terms
Across the record, Byron Bay has reached as high as 97°F and as low as 44°F. A single day has delivered over 11 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
