Philippine Coast Guard (PCG) & PAGASA Maritime Safety Standards
Official sea condition classifications and navigational safety advisories for passenger vessels and artisanal fishing fleets.
| Sea Condition | Significant Wave Height | Philippine Coast Guard (PCG) Advisory |
|---|---|---|
| Slight | 0.5 to 1.25 meters | Safe for all maritime transit, RORO ferries, fastcraft, and open fishing bancas. |
| Moderate | 1.25 to 2.5 meters | Precautionary alert for motor bancas below 250 gross tons. Watch for surface chop. |
| Rough | 2.5 to 4.0 meters | Risky for small seacraft. PCG stations may suspend departures for motor bancas. |
| Very Rough / High (Gale Warning) | 4.0 meters and above | MANDATORY VOYAGE SUSPENSION for fishing boats and small craft. Large vessels on high alert. |
Philippine Marine Weather & Tides FAQ
What triggers an official PAGASA Gale Warning?
PAGASA issues an official Gale Warning when forecast sea surface winds reach 45 to 63 km/h (24 to 34 knots) and significant wave heights reach 4.0 meters and above, typically generated by monsoons (Amihan/Habagat), severe pressure gradients, or passing tropical cyclones.
Which vessels are prohibited from sailing during a Gale Warning?
Under Philippine Coast Guard (PCG) Memorandum Circular No. 02-13, fishing boats and motorized passenger bancas below 250 gross tonnage are strictly prohibited from venturing into open waters when a Gale Warning is active over their seaboard.
How are high and low tides determined in Philippine waters?
The Philippine archipelago primarily experiences semi-diurnal and mixed tidal cycles, resulting in two high tides and two low tides within roughly 24.8 hours. These water level changes are driven by gravitational interactions between the earth, moon, and sun.
Where can passengers confirm RORO ferry cancellations?
Passengers commuting along major ferry routes (Batangas to Calapan, Matnog to Allen, Iloilo to Bacolod, Cebu to Tubigon) should monitor local Philippine Coast Guard station advisories and maritime terminal offices prior to departing for the port.
