Stillwater Regional Airport is an airport with the ICAO code KSWO and the IATA code SWO. Country: United States. Nearest settlement listed in the database: Stillwater. OurAirports classifies it as a medium-sized airport. Its ICAO code starts with the KS prefix, which marks airports in United States. The four-letter code KSWO is used in flight operations and weather reports, while the three-letter IATA code SWO is used for ticketing and baggage handling. The airport reference point sits at 36°09'44"N, 97°05'08"W, at an elevation of 1,000 ft (305 m) above sea level. The applicable time zone is America/Chicago.

| Threshold | Course | Length | Width | Surface |

The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
What the METAR reports from KSWO for 2023-2025 show - counted hour by hour.
We computed these statistics from 26,088 METAR reports issued by KSWO in 2023-2025. VFR conditions prevailed 87% of the time, MVFR 8% and IFR or LIFR 6%. Best month for VFR flying: July (96% of hours VFR). Most IFR and LIFR hours: January (12%).
Through the day, IFR or LIFR conditions are most frequent around 14:00 UTC (9% of reports at that hour) and least frequent around 01:00 UTC (3%).
Fog (FG) was reported on 13 days a year on average, most often in December. Thunderstorms (TS) occurred on 28 days a year on average, and snowfall on 7.
The wind most often blows from S (180°) - 17% of reports. Calm (0 kt) made up 10% of reports, and gusts of 25 kt or more appeared in 6%. Warmest month: August (average high 34.8 °C); coldest: January (average low -2.8 °C).
Day counts are for the selected period (for all years - the yearly average).
The top of each bar is the average daily high, the bottom the average daily low (usually around dawn), in °C.
Most often: S - 17% of reports. Each petal shows the direction the wind blows from (as in METAR) - the longer it is, the more often. Colour shows wind speed.

According to OurAirports data (compiled from AIP and FAA sources), Stillwater Regional Airport has 2 runways: 04/22 - 1,525 m long (5,002 ft), 23 m wide, asphalt surface; 17/35 - 2,256 m long (7,401 ft), 30 m wide, asphalt surface.
The longest of them is 17/35, at 2,256 m.
The thresholds are oriented as follows: 04/22 on 40° and 220° magnetic, 17/35 on 170° and 350° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 04/22 axis, wind from the south-east (around 130°) or from the north-west (around 310°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 40° or 220° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
Weather reports for Stillwater Regional Airport are published under the ICAO code KSWO. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the KSWO report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KSWO, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Chicago zone is GMT-06:00 in winter and GMT-05:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Cushing Municipal Airport (KCUH, 37 km), Guthrie-Edmond Regional Airport (KGOK, 46 km), Chandler Regional Airport (KCQB, 54 km). When no report is available for KSWO, they usually give the best approximation of conditions in the area.
