Weather extremes

How extreme does Homer's weather get?

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

🔥 Hottest day
103°F Jul 15, 1977

That is about 20°F hotter than a normal July afternoon in Homer (typical high near 83°F).

❄️ Coldest night
-20°F Jan 18, 1976

About 38°F colder than a normal January night in Homer (typical low near 18°F).

About 94% of a typical August's rain in a single day (Homer averages roughly 3.8 in across the month).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Homer's record heat sits well above even a hot day for the season — July's 103°F is about 20°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Homer's warmest days reach the low 80s°F and its coldest nights drop to the high 10s°F. But across the record it has gone as high as 103°F and as low as −20°F. A single day has delivered over 4 inches of rain or close to 16 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
