Massive South Pacific Swell Forecast: Tahiti, Hawaii, and the Americas

A powerful low-pressure system is forecast to develop in the Southwest Pacific, triggering a significant swell event expected to impact Tahiti, Hawaii, and the West Coast of the Americas between May 26 and early June 2026.

The event is being driven by a series of storms tracking across the South Pacific. According to reporting from Surfer, one specific system moving out from beneath New Zealand is expected to rapidly intensify into a massive low-pressure system, serving as the primary producer of the swell.

The swell energy is projected to hit Tahiti and French Polynesia first with the highest intensity, before moving north toward Hawaii and eventually spreading across the Americas.

Tahiti and French Polynesia Forecast

Surf is expected to build steadily in Tahiti and French Polynesia through May 26, 2026, peaking that night before gradually easing on May 27, 2026.

Due to the size of the storm and its proximity to the islands, a solid south-southwest swell pulse in the 190–210° range is anticipated. Expert-only breaks, specifically Teahupoʻo, are forecast to see powerful double- to triple-overhead sets during the peak of the event.

The largest waves at Teahupoʻo could potentially reach 15 to 20-plus feet on the face, particularly from late May 26 into early May 27, 2026.

Wind conditions are expected to remain breezy but favorable for southwest-facing reefs. Side-offshore east-southeast winds are forecast for May 26, 2026, shifting to more easterly offshore winds on May 27, 2026, which should help maintain cleaner conditions at exposed breaks.

Hawaii South Shore Outlook

The swell is expected to reach Hawaii a few days after hitting French Polynesia. Because the storm’s strongest winds are forecast to be aimed east of the islands, the overall size potential for Hawaii will be limited compared to Tahiti.

Despite the limited size, south shores are expected to see a worthwhile run of surf. Many standout exposed breaks are forecast to reach the chest- to head-high range, with occasional overhead sets during the peak of the south-southwest swell (180-200°).

The strongest surf in Hawaii is expected during the latter half of May 29, 2026, and throughout May 30, 2026.

Conditions are expected to be clean, as typical east-northeast trade winds are likely to accompany the swell, providing groomed surf across premier south shore breaks.

Americas and Central America Forecast

The south-southwest swell (200-215°) will eventually propagate to the Americas following its passage through the Pacific Islands.

Initial long-period forerunners are expected to arrive over the weekend of May 30-31, 2026, with the primary body of the swell arriving during the first few days of June 2026.

Surf is expected to rise to the head-high zone across many locations in California, Mexico, and Central America. Overhead sets are expected at standout spots, with the strongest overhead conditions forecast for Mexico and Central America.

Specific locations, such as Puerto Escondido in Mexico, may see extra-large conditions.

For most regions in the Americas, the most favorable wind conditions are expected during morning hours, with seabreezes likely developing in the afternoons.
