Canada’s only complete climate database

Canadians are no stranger to extreme weather. From extreme heat to bitter cold and everything in between, Canada gets it all. With Weatherlogics’ rich climate database, you can accurately quantify these extremes.

Weatherlogics has Canada’s only complete climate database. Our database contains weather and climate data, records, extremes, and normals for every location in Canada on an hourly, daily, and monthly basis. Records go back to the 1800s in many locations!

With countless options available, it’s easy to retrieve past weather data and climate records or normal for any location in Canada.

Can’t I Just Use Government Data?

Canadian governments collect a lot of weather data, but they don’t provide complete climate statistics or record keeping. The climate records that are provided are often incomplete or inaccurate, which is why we’ve assembled a complete database with this information. To accurately assess climate records, all available data must be used. The tables below show just a few examples of how Weatherlogics’ data covers a significantly longer period of time compared to the same government data.

Quality First!

Due to cutbacks, government climate data only undergoes minimal automated quality control (QC). However, Weatherlogics' database has implemented an extensive data quality-control and repair system. Not only do we QC all data points, we also repair missing data by retrieving it from other sources. Furthermore, each Weatherlogics data point has a quality-control flag, indicating if there are any issues. We've scanned millions of alternative data sources to ensure you get the most complete climate data possible!


The small border town of Gretna, Manitoba has been taking weather observations at its climate station since 1885! Unfortunately, a large amount of data is missing, including 90% of the data between 1966 and 1995 in government records. Fortunately, Weatherlogics has been able to repair this huge gap, with our database boasting 99.7% data coverage during that time period!


Uses cases

Climate data can be used for a wide variety of cases. This data is useful to the media, insurance companies, data scientists, and developers. Check out some specific use cases below:
