Newport-Bermuda 2026 — the Gulf Stream isn’t where you want it

Newport-Bermuda 2026 — the Gulf Stream isn’t where you want it

Tidetech’s Penny Haire and Dr Roger Proctor on the race within the Newport–Bermuda Race

Six hundred and thirty‑five nautical miles from Newport to St David’s Head looks simple enough on a chart — set the course, manage the wind shifts, keep the boat moving. But everyone who has raced to Bermuda knows the race is rarely decided by the straight line. It’s decided by the water moving underneath it.

“The Gulf Stream is the defining feature of this course,” said Penny Haire, CEO of Tidetech and a sailor who has spent decades navigating with currents in mind.

“Most of the race feels like a drag race,” she said. “Then you get to the Stream, and suddenly the ocean starts posing harder questions.”

Ahead of this year’s Newport–Bermuda Race, Tidetech will publish a rolling series of high‑resolution Gulf Stream crossing analyses. The early analysis is uncomfortable — if you’re planning to cross on the rhumb line, the ocean may not be on your side.

A meander sitting on the track

On a direct 150° true course from Fort Adams to Bermuda, Tidetech’s latest analysis places the north wall of the Gulf Stream roughly 280 nautical miles from the start — about 44 per cent of the way down the course.

“You’re in the Stream for around 35 to 40 miles on that line,” Haire says.

“That’s fairly typical. What isn’t typical is the structure of the Stream where you meet it.”

According to Tidetech’s chief scientist, Dr Roger Proctor, the complexity comes from a pronounced northward meander that has pushed well up towards 40°N near 68.5–69°W — right on the crossing longitude.

“This is one of the more dynamically active parts of the Gulf Stream,” Proctor said.

“Eddies and meanders form regularly here, and they can result in quite different current directions over surprisingly small distances.”

As things stand, the rhumb line clips the western foot of that meander — the least forgiving part of the structure.

When two knots really matters

Through the crossing band, Tidetech’s Global Combined Currents product and dedicated Gulf Stream model show a strong, coherent Stream, with a core running at roughly 2.8 to 3.5 knots.

Resolved along the course, that translates into an adverse set of roughly 0.9 to 2.7 knots for boats heading directly for Bermuda.

“Two knots of foul current is not a rounding error,” Haire said.

“Over the in‑Stream leg, it’s the difference between sailing competitively and watching boats slip away.”

Proctor is quick to add that this is not about dramatic ocean conditions.

“High winds and big seas get a lot of attention,” he says. “But in this race, relatively modest differences in current direction and strength can create separation that lasts for days.”

The mirage in the free forecast

Some public, coarse‑resolution models suggest a more optimistic picture — hinting at fair current on the south‑eastern side of the crossing that makes the direct route look attractive.

“That’s where teams need to be careful,” Haire said.

“Those models are smoothing a very sharp western boundary current across grid boxes that are tens of kilometres wide.”

Tidetech’s higher‑resolution view tells a different story. Its sea‑surface‑temperature (SST)  analysis, resolved at roughly one kilometre, places the thermal front exactly where the current fields locate the meander. Independent satellite infrared analysis lines up with that position as well.

“When SST, current models and satellite observations all point to the same structure, that’s a strong signal,” Proctor said.

“At the moment, they’re all saying the same thing. The favourable limb suggested by the coarse models is likely a mirage.”

There is no ‘standard’ Gulf Stream crossing

One of the most persistent traps in Newport–Bermuda preparation is assuming that last year’s solution still applies.

Proctor points to the 2024 race as a case in point.

“In 2024, the strongest currents sat just east of the rhumb line,” he says. “There was a pronounced meander with south‑easterly flow that rewarded boats willing to step off the shortest track.”

The current picture is very different.

“There isn’t a standard Gulf Stream crossing,” Proctor said.

“What worked in 2024 is not what we’re seeing now. That’s why up‑to‑date information is vital.”

A moving target

There is one final complication and it’s the reason Tidetech is updating its analysis every three days.

“The Gulf Stream does not sit still,” Proctor said.

“Meanders propagate east at anything from three to eleven kilometres a day. Crests can pinch off into rings. The feature you cross today will not be the one you cross on race day.”

That mobility is what turns static charts into liabilities.

“This is a snapshot,” Haire said.

“Useful, but incomplete on its own. The real value is in tracking how the structure moves, where the adverse wall shifts, and where genuinely fair water might open up.”

For crews lining up in Newport, the message is clear.

“Sail the ocean that’s actually there,” Haire said. “Not the one you hope is there.”
