Northwest Palawan

Robert Chang

During the Northeast monsoon, winds are generally below 20 knots but may occasionally exceed 30 knots in the first half of the Northeast monsoon (Oct - Dec). Waves are generally below 2.5m but can occasionally exceed 4.5m during this period. The lowest waves occur during the Spring transition (April) when waves are usually below 1.5m.

Of the two monsoons, the Southwest monsoon is on the average (ie: discounting the direct effects of Tropical Cyclones) rougher than the Northeast monsoon. This is largely due to the longer fetch from the southwest, combined with surges in the Southwest monsoonal flow. Waves are generally below 2.5m but may occasionally exceed 5.5m at the height of the monsoon (July). Winds are generally below 20 knots but can sometimes exceed 40 knots around the same period.

Tropical Cyclones

Tropical Cyclones occur most frequently during the Northeast Monsoon and would cause most of the extreme weather experienced off northwest Palawan.

From October to January, Tropical Cyclones developing to the east of the Philippines frequently track westwards into the South China Sea. They also occur farther south. Such storms have a direct impact on northwest Palawan.

But Tropical Cyclones also affect the area indirectly. During the Southwest monsoon, Tropical Cyclones passing east of Luzon can cause intensifications in the monsoonal flow, bringing high seas and squalls.
