El Niño's Return Promises Shifts in Global Surf Conditions

After years of persistent La Niña conditions, the Pacific Ocean is poised for a dramatic shift towards a strong El Niño event in 2026. Oceanographers explain how the redistribution of warm water across the equatorial Pacific will reshape global surf patterns, with potential impacts ranging from decreased easterly swell energy on Australia's East Coast to more consistent Southern Ocean swells further south.

Why it matters

The transition from La Niña to El Niño represents a fundamental reset of the Pacific's oceanic system, with far-reaching implications for surf conditions worldwide. Understanding these cyclical patterns is crucial for surfers, coastal communities, and anyone invested in the health and dynamics of the world's oceans.

The details

The prolonged La Niña period has saturated the western Pacific with warm water, driven by thermal expansion. As the persistent easterly trade winds begin to relax and even reverse, this excess heat will be redistributed eastward, creating a powerful flow of warm water that is expected to fuel a robust El Niño event. Westerly wind bursts have already contributed to a substantial 4-5°C anomaly in subsurface sea temperatures across the equatorial Pacific, setting the stage for the El Niño's arrival.

• The shift towards El Niño has been underway since March 2026, with several westerly wind bursts accelerating the process.
• Experts predict a potent El Niño event will peak during the spring and summer of 2026.

What’s next

Meteorologists and oceanographers will continue to closely monitor the development of the El Niño event, providing updated forecasts and insights on its potential impacts on global surf conditions in the coming months.
