Weather Briefing

MVFR

Clark International Airport / Clark Air Base is currently reporting marginal VFR (MVFR) conditions with few clouds at 2,000 feet and 8 km visibility.

Wind Analysis

Winds are from the north (360°) at 8 knots. Runway 02L/20R is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 8 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 27°C (81°F) with a dewpoint of 24°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 30 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Temporary VFR conditions are forecast between 18:00Z and 00:00Z. Temporary MVFR conditions are forecast between 00:00Z and 06:00Z.

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 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 Clark International Airport / Clark Air Base

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

Overview

Clark International Airport serves as a strategic medium-sized airport located in Mabalacat, Philippines, at an elevation of 484 feet MSL. Positioned at coordinates 15.186000, 120.559998, the airport features two parallel concrete runways, each 10,499 feet long, supporting a variety of aviation operations. Its historical significance as a former Air Base contributes to its robust infrastructure and strategic location.

Flying Conditions

Meteorological data indicates predominantly favorable flying conditions, with 62.9% of observations reporting VFR conditions and an additional 34.3% in MVFR range. The airport experiences consistent wind patterns from the North at an average of 4.4 knots, with maximum gusts up to 20 knots. Temperature ranges between 19°C and 34°C, with an average of 26.8°C, creating generally stable atmospheric conditions for flight operations.

Notable Features

Both runways (02L/20R and 02R/20L) demonstrate identical operational characteristics, with 100% favorable wind alignment and minimal average crosswind of 2.1 knots. The airport's elevation and geographic position suggest a relatively flat terrain environment. Pilots can expect consistent runway performance with substantial runway lengths allowing operations for a wide range of aircraft types.

Approach Considerations

January, December, and October represent the best months for VFR flying conditions at Clark International Airport. With near-zero instances of fog and consistently high visibility averaging 10 statute miles, approaches and departures typically present minimal meteorological challenges. The parallel runway configuration provides operational flexibility, with both runways offering identical wind-related performance characteristics.
