The county links lead to a page that includes data from the National Weather Service Cooperative Observer Program and the Oklahoma Mesonet. Quick climate facts and longer, more detailed climate data can be found for each county. Information concerning temperature, precipitation, humidity, wind, soil, freeze data, extremes and normals can all be found in the individual county pages.
Weather Station Monthly Summaries provides a table of daily Mesonet observations with monthly values included. This program has the option of selecting a specific month, year, Mesonet station, and format (HTML or PDF).
Monthly Climate Normals by County provides climatological information for each county, in addition to monthly heating degree-days, cooling degree-days, precipitation, and temperature normals.
The Normal Monthly Temperature Table provides the monthly 30-year air temperature normals per county.
The Normal Monthly Precipitation Table provides the monthly 30-year precipitation normals per county.
This publication includes the Oklahoma normals for the monthly and annual maximum, minimum, and mean temperature (degrees F), monthly and annual total precipitation (inches), and the heating and cooling degree days (base temperature of 65 degrees F). The normals include observations from the National Weather Service Cooperative Network and Principal Observation (First-Order) locations.
Monthly values for maximum temperature, minimum temperature, precipitation, and snowfall, if available, by cooperative observer station.
Temperature and precipitation extremes, 30-year normals (or a surrogate normal), and exceedence-of-threshold frequencies for each month for a selected station.
