Weather extremes

How extreme does Isangel's weather get?

The hottest, coldest, wettest and snowiest days Isangel 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 (1973–present), from the Tanna station 11 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 Isangel has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
104°F Jan 16, 1979

That is about 17°F hotter than a normal January afternoon in Isangel (typical high near 87°F).

❄️ Coldest night
48°F Jun 2, 1979

About 16°F colder than a normal June night in Isangel (typical low near 64°F).

More rain in a single day than Isangel usually gets in the whole month of December (typical December total about 1.8 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.

Isangel's record heat sits well above even a hot day for the season — January's 104°F is about 17°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, Isangel's warmest days reach the high 80s°F and its coldest nights drop to the low 60s°F. But across the record it has gone as high as 104°F and as low as 48°F. A single day has delivered over 14 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 20 years of daily observations at Tanna, a weather station, about 11 km from the city centre. The underlying daily records come from NOAA's global station network.
