What a year in Livermore feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 169 frost-free days a year
In half of years the last 32° night comes by April 26 and the first by October 12. Frost and day counts come from NOAA’s station at Dakota City, IA, 10 miles from the town’s center, at about the same height.
The 2023 USDA map puts Livermore’s center in zone 5a: the coldest night of a typical winter, averaged over 1991–2020, reaches about −18°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Livermore
91% 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 Dakota City, IA.
Living with Livermore’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
169 frost-free days in zone 5a. The last frost comes by Apr 26 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 12.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September.

Warmer than it used to be
The last 30 years in Livermore averaged 0.6° warmer than the 1900s. The biggest change is in December (+2.0°).
A smaller shift than in 97% 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 Livermore compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Livermore’s place among Iowa’s.
