Weather extremes

How extreme does Kīhei's weather get?

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

Based on 34 years of daily weather observations (1991–present), from the Kahului Airport station 14 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 Kīhei has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
104°F Mar 29, 2017

That is about 22°F hotter than a normal March afternoon in Kīhei (typical high near 82°F).

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.

Kīhei's record heat sits well above even a hot day for the season — March's 104°F is about 22°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, Kīhei'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 44°F. A single day has delivered over 6 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 30 years of daily observations at Kahului Airport, a weather station, about 14 km from the city centre. The underlying daily records come from NOAA's global station network.
