Oklahoma Climatological Survey

Climate of Oklahoma

Oklahoma Climate Overview

The Oklahoma Climate Overview describes the features of the climate across the entire state. Included in the overview is information about the topography of Oklahoma. Temperature and precipitation are discussed in detail along with information about snowfall, freeze periods, and growing seasons. Severe weather, floods, and drought are also previewed in the climate overview.

County Climatologies Page

The County Climatolgies are an in-depth look into the climate of each County in Oklahoma. Both Oklahoma Mesonet and the National Weather Service Cooperative Observer Program data were used to help give a quality representation of the county climates. General information is given about the geography of the county and an overview of the climate is presented at the beginning of each document. Other data included are temperature, precipitation and snowfall normals and extremes, first and last freeze data, exceedence values, growing season data, wind data, humidity and moisture, soil temperature data, and tornadoes. These in-depth documents are ideal for several types of planning purposes, including farming and development. In addition to the detailed tables, a "Quick Facts" document is provided for each county. The Quick Facts provide a one-page look at annual normals and extremes for the county.

Mesonet and COOP Station Data Page

Data from individual Oklahoma Mesonet sites and National Weather Service COOP stations can be accessed through the stations page. Tables of the same data as used in the County Climatologies are available for each long-term climate station. Sites are arranged by Mesonet Station or COOP Station. This provides more local information than the county overview. The National Weather Service COOP stations are based on long-term temperature and precipitation observations and include monthly averages and extremes, exceedence values, freeze data and growing season data. Oklahoma Mesonet stations also include summarized temperature and precipiations data, but also include wind roses, humidity and moisture data and soil temperature data. These documents are very helpful for looking at data for a particular place within a county.
