Links to Historical Weather Data

Collection and archiving of accurate weather data is important for a variety of water supply, engineering and infrastructure planning reasons, not just to predict when the next powder day is happening!

Historical precipitation information is used in a variety of engineering related analysis. By using accurate historical rainfall data, over an appropriate period of time, proper water supply planning and design for infrastructure can be determined.  Some examples:

  • Right-sizing of stormwater facilities can save millions of dollars
  • Creating better designs that prevent localized flooding
  • Estimating future demands for long term water supply forecasting

Accurate weather data collection and the corresponding review and processing of regular weather data is no easy task. The City of Bend has chosen to partner with weather experts who use federal weather data standards, making the weather data even more useful for a variety of related analysis and forecasting.

Below are links to local weather stations with a summary of data types collected. Data and more information can be found at each station's web site.  Please note:  There may be additional information available from paid weather services, and we do not have those listed here.
