What a year in Lakeside feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 151 frost-free days a year
In half of years the last 32° night comes by May 5 and the first by October 5. Frost and day counts come from NOAA’s station at Wheat Ridge 2, CO, 3 miles from the town’s center, at about the same height.
The 2023 USDA map puts Lakeside’s center in zone 6a: the coldest night of a typical winter, averaged over 1991–2020, reaches about −8°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Lakeside
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 Wheat Ridge 2, CO.
Living with Lakeside’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
151 frost-free days in zone 6a. The last frost comes by May 5 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 5.
Months with highs of 62–84° and lows of 40° or more: May, June and September.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Lakeside, CO | 20° | 89° | 17" | 76" |
| Herriman, UT | 22° | 90° | 15" | 74" |

| Chadron, NE | 14° | 89° | 18" | 50" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Lakeside averaged 1.4° warmer than the 1900s. The biggest change is in March (+3.5°).
A bigger shift than in 55% 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 Lakeside compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Lakeside’s place among Colorado’s.
