If you’ve ever flown to Hawaii and felt the ride get a little shaky over the Pacific, you’re not alone — and there’s growing evidence that this turbulence may be more than just a one‑off in-flight annoyance.

Recent research suggests that flights to Hawaii and along the U.S. West Coast are experiencing higher levels of turbulence than in past decades, with some estimates showing a 10%–30% increase in turbulence encounters in these regions.

A combination of scientific studies spanning several years points toward a trend of increasing turbulence. One influential analysis from the University of Reading in the U.K. found that so‑called “clear‑air turbulence” — bumps in the sky that happen even without visible storms — has been gradually increasing. In the area between Hawaii and the western United States, the data suggests it’s now 10%–30% more likely to occur than in past decades.

Experts believe climate change plays a role. As global temperatures rise, changes in the jet stream — the fast‑moving air currents that aircraft often fly through — can lead to more unpredictable air movement and vertical wind shear, both key drivers of turbulence.

While severe turbulence remains relatively rare, travelers might notice more frequent bumps during flights — especially on longer trans‑Pacific routes like those to and from Hawaii. Forecasts likely won’t change drastically overnight, but awareness and preparation can help make your journey feel smoother, even when the skies get a little rougher.

A frequent traveler quoted in the report even noted recently experiencing longer stretches of “massive turbulence” on Aloha flights — though others with different experiences pointed out that results vary by route and weather conditions.

More turbulence doesn’t mean flying is unsafe. Modern aircraft are engineered to handle these conditions, and pilots adjust routes and altitudes to avoid the worst of the bumps whenever possible. However, understanding trends helps travelers set expectations, pack smartly, and buckle seat belts with confidence.

If you’re planning your next trip to Hawaii, consider this trend a reminder to stay informed — and maybe hold off on that coffee refill right before landing.
