Weather Briefing

LIFR

Juanda International Airport is currently reporting low IFR (LIFR) conditions with few clouds at 1,800 feet and 0.5 km visibility.

Wind Analysis

Winds are from the north-northeast (30°) at 13 knots. Runway 10/28 is favored with a 4-knot headwind and 12-knot crosswind component.

Visibility & Ceiling

Visibility is severely reduced to 0.5 km, likely due to fog, mist, or precipitation. Special VFR or an IFR clearance may be required. No ceiling exists. Cloud layers reported: few at 1,800 ft (CB). Caution: cumulonimbus (thunderstorm) clouds reported at 1,800 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 25°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

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

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.
