Runways of SBOI
| Threshold | Course | Length | Width | Surface |
|---|---|---|---|---|
| 3 | 30° | 1,200 m (3,937 ft) | 30 m (98 ft) | asphalt |
| 21 | 210° |
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 Oiapoque Airport - statistics from METAR reports
What the METAR reports from SBOI for 2023-2025 show - counted hour by hour.
We computed these statistics from 22,363 METAR reports issued by SBOI in 2023-2025. VFR conditions prevailed 74% of the time, MVFR 15% and IFR or LIFR 11%. Best month for VFR flying: September (89% of hours VFR). Most IFR and LIFR hours: May (20%).
Through the day, IFR or LIFR conditions are most frequent around 10:00 UTC (39% of reports at that hour) and least frequent around 23:00 UTC (1%).
Fog (FG) was reported on 33 days a year on average, most often in July. Thunderstorms (TS) occurred on 6.4 days a year on average, and snowfall practically never.
The wind most often blows from NE (45°) - 9% of reports. Calm (0 kt) made up 17% of reports, and gusts of 25 kt or more appeared in <1%. Warmest month: October (average high 33.7 °C); coldest: October (average low 22.7 °C).

Runway headings and wind
The thresholds are oriented as follows: 3/21 on 30° and 210° 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 3/21 axis, wind from the south-east (around 120°) or from the north-west (around 300°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 30° or 210° 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 SBOI
Weather reports for Oiapoque Airport are published under the ICAO code SBOI. 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 SBOI 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 SBOI, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Cayenne 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 Saint-Georges-de-l'Oyapock Airport (SOOG, 5 km), Régina Airport (SOOR, 63 km), Camopi Airport (SOOC, 97 km). When no report is available for SBOI, they usually give the best approximation of conditions in the area.
