What is Extreme Weather Watch?

Updated

Extreme Weather Watch (extremeweatherwatch.com) is a site founded in 2021 that provides an easy interface for looking up historical weather records. If you want to check all-time highs, lows, or average temperatures and rainfall for a specific place, this is the kind of tool that answers that question directly rather than making you dig through raw climate data.

What the site covers

The core of the site is climate records organized by location, and the coverage is broad:

  • U.S. states — all 50 states plus American Samoa, Guam, and the District of Columbia
  • Canadian provinces and territories — from Alberta and British Columbia through to Yukon and Nunavut
  • Australian states and territories — New South Wales, Northern Territory, Queensland, South Australia, Tasmania, Victoria, and Western Australia
  • Other countries — a list that includes Austria, China, Croatia, Cyprus, Estonia, Finland, France, Germany, Greenland, Hungary, Iceland, Ireland, Italy, Kazakhstan, Luxembourg, the Netherlands, Norway, Portugal, Romania, Russia, Serbia, Slovenia, Spain, Sweden, Switzerland, the United Kingdom, and Uzbekistan

So the practical use case is: you have a place in mind and want its historical weather extremes or averages, and you navigate to that state, province, or country to see the records.

Comparison and calculation tools

Beyond single-location lookups, the site groups several comparison and utility pages:

Tool type What it lets you compare or do
Country Comparison Weather comparison between countries
Countries by Cloud Cover Ranking countries by cloud cover
City Comparison Side-by-side comparison of cities
U.S. State Capital Comparison Compare state capitals
100 Largest U.S. Metros Compare major U.S. metro areas
25 Largest Canadian Metros Compare major Canadian metro areas
State Comparison Compare U.S. states
U.S. State All Time Highs / Lows See record highs and lows by state
U.S. State Average Temperatures and Rain Average temperature and rainfall by state
Calculators: Convert Temperature Temperature unit conversion

The comparison pages are the reason to use this site over a single-city weather page: they put multiple locations on the same footing so differences are visible at a glance.

Blog and yearly records

The site also publishes blog articles, including annual reviews of weather records. One example is a 2025 Weather Records article, first published January 09, 2026, which reviews records broken during 2025. These posts are useful if you want a summary of notable extremes for a given year rather than a single location's data.

Who it's for

This site fits you if you need historical climate records — all-time highs and lows, averages, rainfall — for a U.S. state, Canadian province, Australian state, or one of the listed countries, or if you want to compare weather between places. It is not a live forecast service; the focus is on records and historical data.
