Weather Briefing

MVFR

Sembawang Air Base is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 1,700 feet and 5 km visibility.

Wind Analysis

Winds are from the southeast (140°) at 8 knots. Runway 22 is favored with a 1-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is 5 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 1,400 ft, few at 1,600 ft (CB), scattered at 1,700 ft (TCU). Caution: cumulonimbus (thunderstorm) clouds reported at 1,600 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 28°C (82°F) with a dewpoint of 23°C, indicating moderate moisture conditions.

Forecast Outlook

The TAF forecast covers the next 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Thunderstorm Rain. Temporary IFR conditions are forecast with Thunderstorm Rain between 06:00Z and 09:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Sembawang Air Base

Sembawang Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the SG AIP for current access procedures and restrictions.

Overview

Sembawang Air Base is a medium-sized airport located in Sembawang, Singapore, positioned at coordinates 1.425260, 103.813004. Situated at an elevation of 86 feet above mean sea level, the base serves as a strategic aviation facility in the region. Its infrastructure supports military and potentially joint civil-military aviation operations.

Flying Conditions

Singapore's tropical maritime climate presents consistent temperature and humidity levels throughout the year, which can impact aircraft performance at Sembawang Air Base. The base's proximity to coastal areas may introduce variable wind conditions, particularly during seasonal monsoon transitions. Pilots should anticipate potential wind shear and rapid meteorological changes typical of the Southeast Asian maritime environment.

Notable Features

The airbase features two asphalt (ASP) runways with different orientations: Runway 04/22 measuring 6,255 feet and Runway 05/23 measuring 3,400 feet. These parallel runways provide operational flexibility for different wind conditions and aircraft types. The base's moderate elevation and substantial runway lengths accommodate a range of military and potential civilian aviation requirements.

Approach Considerations

Runway selection will depend on prevailing wind direction, with the two runway configurations offering complementary approach options. The longer Runway 04/22 provides more landing and takeoff flexibility for larger aircraft. Pilots should carefully assess wind vectors and runway characteristics when planning approaches to Sembawang Air Base.
