| Threshold | Course | Length | Width | Surface |
|---|---|---|---|---|
| 18 | 180° | 1,080 m (3,542 ft) | 30 m (98 ft) | asphalt |
| 36 | 360° |
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.
Climate at Syros Airport (Syros Island) - statistics from METAR reports
What the METAR reports from LGSO for 2023-2025 show - counted hour by hour.
We computed these statistics from 25,674 METAR reports issued by LGSO in 2023-2025. VFR conditions prevailed 98% of the time, MVFR 2% and IFR or LIFR <1%. Best month for VFR flying: August (100% of hours VFR). Most IFR and LIFR hours: July (<1%).
IFR and LIFR conditions are rare here at any time of day.
Fog practically did not occur here. Thunderstorms (TS) occurred on 4.7 days a year on average, and snowfall practically never.
The wind most often blows from N (0°) - 33% of reports. Calm (0 kt) made up 3% of reports, and gusts of 25 kt or more appeared in 9%. Warmest month: July (average high 31.5 °C); coldest: February (average low 10.2 °C).

Runway headings and wind
The thresholds are oriented as follows: 18/36 on 180° and 360° 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 18/36 axis, wind from the west (around 270°) or from the east (around 90°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 180° or 360° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
METAR and TAF for LGSO
Weather reports for Syros Airport (Syros Island) are published under the ICAO code LGSO. 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 LGSO 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 LGSO, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Europe/Athens zone is GMT+02:00 in winter and GMT+03:00 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 Mykonos Island National Airport (LGMK, 35 km), Paros National Airport (LGPA, 47 km), Naxos Island National Airport (LGNX, 53 km). When no report is available for LGSO, they usually give the best approximation of conditions in the area.
