Weather Briefing

MVFR

Juanda International Airport is currently reporting marginal VFR (MVFR) conditions with few clouds at 2,000 feet and 5 km visibility.

Wind Analysis

Winds are from the west (260°) at 3 knots.

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 2,000 ft.

Temperature & Moisture

Temperature is 24°C (75°F) with a dewpoint of 24°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 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: Haze.

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 narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. 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 Juanda International Airport

Overview

Juanda International Airport serves as the primary air gateway for Surabaya, the second-largest city in Indonesia. Located at coordinates -7.379830, 112.787003, this large airport handles significant commercial and regional aviation traffic for East Java. The airport sits at a low elevation of 9 ft mean sea level, providing relatively straightforward terrain conditions for aircraft operations.

Flying Conditions

Surabaya's tropical maritime climate presents variable weather conditions for pilots, with potential for humidity and precipitation throughout the year. The airport's low elevation minimizes significant atmospheric variations that might impact approach and landing procedures. Wind patterns across the single runway 10/28 can shift seasonally, requiring pilots to maintain awareness of potential crosswind scenarios.

Notable Features

The airport features a single 9,843 ft asphalt runway (10/28), providing substantial landing and takeoff capability for most commercial aircraft types. Its proximity to the Java Sea and surrounding urban landscape means pilots should anticipate potential thermal and wind shear conditions, particularly during transition between land and maritime environments. The airport's infrastructure supports extensive commercial and passenger operations for the Surabaya metropolitan region.

Approach Considerations

Runway 10/28's significant length of 9,843 ft allows flexible approach options for various aircraft classes and weights. Pilots should anticipate standard instrument approach procedures typical of a large international airport in a tropical maritime setting. Given the low elevation and coastal proximity, maintaining precise altitude awareness during approach is recommended.
