Hardly any U.S. towns see fresher July days than Menlo Park

On a normal January night the air cools to about 43°. It is a dry place: less rain and snow fall here than on 92% of U.S. towns. Warming shows here too: 1.7° more than in 1901–2000, led by August. Long walks are most pleasant from March to November, when afternoons reach 64–74°.

Frost, heat & the growing season

A freeze most winters

Frost and day counts come from NOAA’s station at Moffett Federal Airfield, CA, 8 miles from the town’s center, at about the same height.

Most winters bring a freeze, but not every one. A night at 32° or below comes in about 70% of years at Moffett Federal Airfield, CA (about 7 winters in 10), and averages 2.4 a year.

Then and now

Warmer than it used to be

The last 30 years in Menlo Park averaged 1.7° warmer than the 1900s. The biggest change is in August (+2.0°).
