Built from NOAA GHCN station records · 40,000+ US zip codes · Trusted by Fortune 500 and university teams

Get four free Excel datasets covering every US zip code: long-term average temperature, rainfall, snowfall, and humidity, all built from official NOAA station records. Each dataset gives the single long-term average value for every US zip code. Enter your email below and we will send one message containing all four download links.

Look up the climate by zip code

Every US zip code has its own climate fingerprint: decades of temperature, rainfall, snowfall and humidity records that describe what a place is actually like — not what the forecast says for tomorrow. Enter a zip code below to see the average weather by zip code, how it ranks against every other US zip, and a few things those long-term numbers say about snow, growing seasons and which famous places share its climate. Every figure comes from the same NOAA-built dataset you can download free on this page.

Frequently asked questions

Is it really free?

Yes. There is no credit card, no trial, and no payment step. You enter an email address and receive all four datasets.

What’s the catch?

Yes, within a single organization. You can use the data in internal analysis, reports, and client work, but you may not redistribute or resell the files themselves. See our terms for details.

How current is the data?

The averages cover a rolling 10-year window, currently July 2016 through June 2026, and are updated monthly as NOAA publishes new station records.

What units are used?

Temperature is in degrees Fahrenheit, rainfall and snowfall are in inches, and humidity is in percent relative humidity.

Do you have data outside the US?

The free datasets cover US zip codes only. Paid datasets cover more than 40,000 global locations in daily and monthly form — see pricing.
