Large, strong waves expected on Thursday in Costa Rica’s southern Pacific

The University of Costa Rica’s Ocean Sciences and Limnology Research Center (CIMAR) reported Tuesday that strong waves measuring up to 10 feet will hit beaches along the southern Pacific from Thursday to Sunday.

Strong waves in the region are the result of several tropical storms in the Pacific Ocean, the report said. The largest waves are expected from 2-4 p.m.

Large waves have been registered in the southern Pacific region in recent days, but those expected for next weekend could be more dangerous, experts warned.

“These waves are dangerous mostly for swimmers and small boats,” CIMAR oceanographer Omar Lizano said. Strong [wave] conditions “now occur more frequently, a delicate situation because it has intensified since last year,” he added.

This week’s waves, however, do not pose a hazard for offshore navigation, he said.
