Compared with towns across the U.S., with Nephi’s place in Utah beside it.
What a year in Nephi feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 148 frost-free days a year
In half of years the last 32° night comes by May 10 and the first by October 7. Day counts come from NOAA’s station at Nephi, UT, 0.5 miles from the town’s center, at about the same height; frost dates and degree days from Levan, UT, 10 miles away.
The 2023 USDA map puts Nephi’s center in zone 6b: the coldest night of a typical winter, averaged over 1991–2020, reaches about −4°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Nephi
89% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Levan, UT.
Living with Nephi’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
148 frost-free days in zone 6b. The last frost comes by May 10 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Oct 7.
Months with highs of 62–84° and lows of 40° or more: May, June and September. 2.2 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Nephi from natural hazards, earthquakes are the largest share (61%); heat waves, cold waves, winter storms and ice storms together are 11%. Normals are averages; the hazards page covers the extremes.

Warmer than it used to be
The last 30 years in Nephi averaged 1.3° warmer than the 1900s. The biggest change is in March (+2.9°).
A smaller shift than in 57% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Nephi compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Nephi’s place among Utah’s.
