Assa-Gueyla Airport is an airport with the ICAO code HDAG. Country: Djibouti. Nearest settlement listed in the database: Assa-Gueyla. OurAirports classifies it as a small airport. Its ICAO code starts with the HD prefix, which marks airports in Djibouti. No IATA code is assigned, which is typical for airports without scheduled traffic. The airport reference point sits at 12°11'20"N, 42°38'15"E, at an elevation of 2,050 ft (625 m) above sea level. The applicable time zone is Africa/Djibouti.

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.
According to the infobox on the English Wikipedia, Assa-Gueyla Airport has one runway: 17/35 - 1,405 m long (4,610 ft), unpaved surface.
No OurAirports data is available for this airport, so the figures above come from Wikipedia - a community-edited source that can be out of date. The infobox also gives no runway width. Treat these numbers as indicative and check the current AIP before flying.
The thresholds are oriented as follows: 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 17/35 axis, wind from the west (around 260°) or from the east (around 80°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 170° or 350° 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 Assa-Gueyla Airport are published under the ICAO code HDAG. 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 HDAG 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 HDAG, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The Africa/Djibouti zone stays at GMT+03:00 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 Tadjoura Airport (HDTJ, 54 km), Obock Airport (HDOB, 73 km), Herkale Airport (HDHE, 77 km). When no report is available for HDAG, they usually give the best approximation of conditions in the area.
