Coastal Waters
Coastal waters are the sea areas close to shore, generally more sheltered than open or offshore waters but still subject to PAGASA's marine advisories during a typhoon.
Fishing Advisory
A fishing advisory warns fishing operators of unsafe sea conditions, often tied to a gale warning or rough sea state during a nearby tropical cyclone.
Offshore Waters
Offshore waters are sea areas beyond the coastal zone but not yet in the open sea, typically experiencing rougher conditions than coastal waters during a passing tropical cyclone.
Open Sea
Open sea refers to waters beyond the sheltered coastal zone, where wave heights and wind conditions tend to be more severe during a typhoon than in coastal waters.
Small Craft Advisory
A small craft advisory is a PAGASA notice warning small fishing boats and recreational vessels to avoid sailing due to hazardous wind or wave conditions.
Wave Period
Wave period is the time between successive wave crests, a figure used alongside wave height to assess how hazardous sea conditions are for vessels.
