Weather extremes

How extreme does Arno's weather get?

The hottest, coldest, wettest and snowiest days Arno 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 Majuro Wbas Ap station 31 km away. Updated through June 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 Arno has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
102°F Dec 21, 2022

That is about 16°F hotter than a normal December afternoon in Arno (typical high near 86°F).

About 10°F colder than a normal November night in Arno (typical low near 78°F).

🌧️ Most rain in one day
14.98 in Dec 12, 1972

More rain in a single day than Arno usually gets in the whole month of December (typical December total about 11.4 in).

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.

Arno's record heat sits well above even a hot day for the season — December's 102°F is about 16°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, Arno's warmest days reach the high 80s°F and its coldest nights drop to the high 70s°F. But across the record it has gone as high as 102°F and as low as 68°F. A single day has delivered over 15 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 14 years of daily observations at Arno, a weather station, inside the city. The underlying daily records come from NOAA's global station network.
