| Threshold | Course | Length | Width | Surface |
|---|---|---|---|---|
| 04 | 40° | 1,462 m (4,797 ft) | 46 m (151 ft) | asphalt |

| 08 | 80° | 2,310 m (7,580 ft) | 46 m (151 ft) | asphalt |
| 26 | 260° |
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 EGDY for 2023-2025 show - counted hour by hour.
We computed these statistics from 25,274 METAR reports issued by EGDY in 2023-2025. VFR conditions prevailed 62% of the time, MVFR 27% and IFR or LIFR 11%. Best month for VFR flying: June (79% of hours VFR). Most IFR and LIFR hours: December (19%).
Through the day, IFR or LIFR conditions are most frequent around 05:00 UTC (16% of reports at that hour) and least frequent around 13:00 UTC (7%).
Fog (FG) was reported on 36 days a year on average, most often in May. Thunderstorms (TS) occurred on 1.7 days a year on average, and snowfall on 2.3.
The wind most often blows from SSW (203°) - 12% of reports. Calm (0 kt) made up 1% of reports, and gusts of 25 kt or more appeared in 2%. Warmest month: August (average high 21.9 °C); coldest: January (average low 1.7 °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: SSW - 12% 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), RNAS Yeovilton (Yeovil, Somerset) has 2 runways: 04/22 - 1,462 m long (4,797 ft), 46 m wide, asphalt surface; 08/26 - 2,310 m long (7,580 ft), 46 m wide, asphalt surface.
The longest of them is 08/26, at 2,310 m.
The thresholds are oriented as follows: 04/22 on 40° and 220° magnetic, 08/26 on 80° and 260° 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 RNAS Yeovilton (Yeovil, Somerset) are published under the ICAO code EGDY. 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 EGDY 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 EGDY, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Europe/London zone is GMT+00:00 in winter and GMT+01:00 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 Yeovil/Westland Aerodrome (Yeovil, Somerset) (EGHG, 8 km), Henstridge Airfield (Templecombe, Somerset) (EGHS, 20 km), RNAS Merryfield (Ilminster, Somerset) (EGDI, 22 km). When no report is available for EGDY, they usually give the best approximation of conditions in the area.
