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 Siri Airport - statistics from METAR reports

What the METAR reports from OIBS for 2023-2025 show - counted hour by hour.

We computed these statistics from 14,935 METAR reports issued by OIBS in 2023-2025. VFR conditions prevailed 10% of the time, MVFR 45% and IFR or LIFR 45%. Best month for VFR flying: January (44% of hours VFR). Most IFR and LIFR hours: July (78%).

Through the day, IFR or LIFR conditions are most frequent around 01:00 UTC (83% of reports at that hour) and least frequent around 12:00 UTC (37%).

Fog (FG) was reported on 3.4 days a year on average, most often in April. Thunderstorms (TS) occurred on 4.7 days a year on average, and snowfall practically never.

The wind most often blows from W (270°) - 15% of reports. Calm (0 kt) made up 10% of reports, and gusts of 25 kt or more appeared in <1%. Warmest month: July (average high 36.7 °C); coldest: January (average low 19.9 °C).

Source: routine METAR reports from the Iowa Environmental Mesonet archive (Iowa State University), 2023-2025. Flight categories use the FAA thresholds, widely used as a convention. A day counts when it has at least 12 reports. These are statistics of past conditions - not a forecast or a substitute for a pre-flight briefing.

Runways at OIBS

According to OurAirports data (compiled from AIP and FAA sources), Siri Airport has one runway: 12/30 - 2,544 m long (8,345 ft), 53 m wide, asphalt surface.

Runway headings and wind

The thresholds are oriented as follows: 12/30 on 120° and 300° 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 12/30 axis, wind from the south-west (around 210°) or from the north-east (around 30°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 120° or 300° 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 OIBS

Weather reports for Siri Airport are published under the ICAO code OIBS. 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 OIBS 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 OIBS, check the nearby airports listed below.

Reports always use UTC (the Z suffix). The Asia/Tehran zone stays at GMT+03:30 year-round, so converting to local time is always the same shift.

The closest airports in the database, measured in a straight line from the reference point, are Abu Musa Island Airport (OIBA, 50 km), Bandar Lengeh International Airport (OIBL, 75 km), Sir Abu Nu'ayr Airport (OMSN, 83 km). When no report is available for OIBS, they usually give the best approximation of conditions in the area.
