News about this website

This website contains typical and single-year weather data files in EPW format from many publicly available data sets from around the world.

Aug 2017 - all data sets have been updated with 2017 ASHRAE design conditions (where applicable).

Several countries have added 2 or 3 character abbreviations for provinces -- shorter names -- but longer province names are also shown.

Newly added data sets: Canadian Weather for Energy Calculations (CWEC) 2016 and California Climate Zones 2016.

Additional statistics have been added in the .stat files: UTCI (Universal Thermal Climate Index), Additional Wind reporting, Psychrometric Chart Data, Sunshine/Daylight averages.

TMY3a (US and some others), TMY (US and some others), CWEC (Canada), CTZ (California Climate Zones), CSWD (Chinese Standard Weather Data), BBSR (Germany), NIWA (New Zealand), RMY 2012 (Australia), IMS (Israel), ITMY (Iran), SWERA (multiple countries), INMET and TRY (Brazil), City University of Hong Kong, ISHRAE (India), IMGW (Poland), KISR (Kuwait), JGMY (Japan generated weather), TurTMY (Turkey), ArgTMY (Argentina) and Uruguay (AMTUes) sources have been loaded. Stay tuned to this page for further updates.
