Both have temperature and wind information but not precipitation forecasts.

Historical data is made available by Inmet in two separate ways:

  1. Historical data on temperature, wind and precipitation. Said to be updated daily. Data sits behind user registration and access control.

  2. Historical data on temperature, wind and precipitation from automatic weather stations. Updated hourly. Available in CSV but users have to fill in a captcha.
