Search Weather Dialog

30,000+ Weather files from EnergyPlus.net and climate.onebuilding.org are gathered here. To easily find data relevant to your site, simply type in the name of the city.

If a file is available locally, the Source column will display “LocalFile”. Else it will require an internet connection to access that weather data.

Once a weather file is selected, click the “OK” or “Download” button to either load the file if it was already downloaded as a local file or download and load it from the respective source.

Filtering for type and location

The drop-down menu next to the search bar filters for the type of weather data. By default, it is set to only display TMYx.2004-2018 data as those are the most up-to-date and should be used for most analysis. More options are available by expanding the drop-down.

The search will try to match every sub-string separated by space. The search is always case insensitive. It searches across both the Location, Country, and Data Type fields.
