Weather extremes

How extreme does Avoca's weather get?

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

Based on 19 years of daily weather observations (2006–present), from the Harlan Municipal Airport station 12 km away. Updated through August 2025 — 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 Avoca has recorded — each shown against what a normal day that time of year looks like.
