About WhatWasTheWeather.com

Have you ever wondered what the weather was like on this day last year? Maybe you are planning a trip and want to know what to expect, or perhaps you are just curious about the temperature on a memorable date.

WhatWasTheWeather.com makes it simple. Enter any US ZIP code, and we will tell you the exact high temperature from one year ago today.

How It Works

We use the official NOAA Climate Data Online API to look up historical weather records. NOAA maintains the most comprehensive climate database in the world.

When you enter a ZIP code, we look up the nearest weather station and retrieve the maximum temperature recorded on that exact date one year earlier.

Why We Built This

Weather history is fascinating. Whether you are planning an outdoor event, curious about the weather on a special date, or researching climate patterns, we make it easy.

No sign-ups, no accounts, no data collection — just enter a ZIP code and get your answer.

About the Data

Temperatures are reported in degrees Fahrenheit and come from the Global Historical Climatology Network (GHCND), maintained by NOAA\s National Centers for Environmental Information.
