September 2025 - Added NORCERRA files. Typical Meterological files for all municipalities in Norway. The files are based on CERRA data from 1991-2020. September 2025 - Added RMY2024 files. Typical Meteorological data and future data for 83 Locations in Australia. All RMY files have their own folder Australia RMY. September 2025 - Updated the historical NIWA files - note that DDY files with ASHRAE suffix are 2025 Design Conditions and without that suffix are the 2005 Design Conditions embedded in the epw files. NIWA files have their own folder: New Zealand NIWA September 2025 - Added NIWA2024 files - again note that DDY files with ASHRAE suffix are 2025 Design Conditions and without that suffix are the NIWA calculated Design Conditions embedded in the epw files. NIWA files have their own folder: New Zealand NIWA October 2024 - Changed Turkey to Turkiye - UN agreed to this change in 2022. Not everyone has stepped up.October 2024 - California Climate Zone (CTZ2022) have been uploaded. October 2024 - California Climate Zones (CTZ2022) have been uploaded. September 2024 - Brazil future files have been uploaded. September 2024 - the Ireland MetEireann dataset has been uploaded. Past and future files are included. July 2024 - all data sets refreshed and TMYx now includes data through 2023 TMYx climate files in this update -- locations/recent (2009-2023):
July 2023 - CWEC2020 v2 (564 sites) and CWEC TDY 2020 v2 (564 sites) July 2023 - Updated Uruguay AMTUes data to V2.5. November 2022 - New Building Reference Year and Future Climate Data set for 564 Canadian Locations. Details on the sources page. May 2022 - CWEC 2020 - 564 locations added April 2022 - Completely updated worldwide TMYx dataset which adds more than 2500 new locations (>15% increase), bringing the total to more than 16,100 locations. These include weather station meteorology data through 2021 and corresponding solar radiation from the ERA5 reanalysis data set. The ERA5 data, courtesy of Oikolab, provides a comprehensive, worldwide gridded solar radiation data set based on satellite data. The new data (and all other weather files on the site including the 2004-2018 TMYx) also now include the latest ASHRAE 2021 design conditions. Another new data set are the hourly Climate Normals for the U.S. These are typical climate conditions for thousands of locations across the United States. Normals are calculated for a uniform 30-year period, and consist of annual/seasonal, monthly, daily, and hourly averages and statistics of temperature, precipitation, and other climatological variables from almost 15,000 U.S. weather stations. We have converted the hourly normal for the 600 stations available each for 1981-2010, 1991-2020, and 2006-2020 into EPW and other formats. |

Stay tuned to this page for further updates.
TMYx - see below for details on locations. TMYx files are derived from ISD (US NOAA's Integrated Surface Database) with hourly data through 2021. TMYx files are created using the general principles from the IWEC (International Weather for Energy Calculations) that was published in 2001. The resultant files have been peer reviewed by interested parties.
A papers section has been added.
