Is the Resurrection Bay rough? What to expect on the crossing
Inside the bay, mostly not, but the longer Kenai Fjords cruises leave it for the open Gulf of Alaska. The National Park Service says half-day tours stay in the more protected waters of Resurrection Bay, and Major Marine Tours says its 6 hour cruise crosses the Gulf for a short time, where seasickness is more likely. NOAA's Coast Pilot says conditions in the Gulf are often roughest in the waters south of Seward.

Why does the Resurrection Bay get rough?
Resurrection Bay runs about 16 miles inland from Cape Resurrection with great depths and steep, high shores, and Major Marine Tours calls it the calmer, protected water on its half-day cruises. The rough water is outside it: NOAA's Coast Pilot says Gulf of Alaska conditions are often roughest south of Seward, where a long fetch to the east and southeast builds sea and swell. Wave heights there reach 20 feet (6.1 m) or more up to eight percent of the time in November, the roughest month. Right at the mouth, the passage between Barwell Island and Cape Resurrection is reported dangerous for small craft in east weather because of tide rips, confused seas and seas bouncing back off the cliffs.
When is the Resurrection Bay roughest?
NOAA's Coast Pilot says the early part of winter is the roughest part of a rough season in the Gulf of Alaska, with November the roughest month south of Seward and gales most likely in November and December. From May through August, seas of 20 feet (6.1 m) or more are unlikely, but September weather is often a harbinger of winter. At NOAA's Cape Cleare buoy in the northern Gulf, the daily maximum wave height averages 1.47 m in July and 3.79 m in December.

The crossings that cross it
| Route | Typical duration | What to know |
|---|---|---|
| Seward 4 hour wildlife cruise (Major Marine Tours) | 4 hours | Stays in the calmer, protected waters of Resurrection Bay. |
| Seward to Aialik Bay glacier (6 hour national park cruise, Major Marine Tours) | 6 hours | Crosses the Gulf of Alaska for a short time, where the operator says seasickness is more likely. |
| Resurrection Bay Express Tour (Kenai Fjords Tours) | 3 hours | A captain-narrated tour of the bay, the shortest of the cruises listed here. |
| Seward to Northwestern Fjord (8.5 hour cruise, Major Marine Tours) | 8.5 hours | Spends the most time in the open ocean. The operator does not recommend it for people prone to seasickness. |
What helps on this crossing
- Pick the route before the date. The National Park Service says half-day tours stay in the more protected waters of Resurrection Bay, while full-day tours go out to the tidewater glaciers.
- Read the cruise page. Major Marine Tours does not recommend its 8.5 hour cruise for people prone to seasickness because it travels through the open Gulf of Alaska, and points them to its half-day cruises.
- Once the boat leaves the bay, watch the actual horizon line rather than the deck or the waves, and put your phone away. The Coast Pilot says sea and swell build from the east and southeast here, so an east or southeast storm in the forecast is the one to watch before a full-day trip.
For the full toolkit see the seasickness guide, or what to do once it has already started. For what the trials actually say about the oldest trick on that list, see the verdict on looking at the horizon. If the rocking follows you ashore afterwards, that is land sickness, which is normal, and it passes.
Frequently asked questions
Is Resurrection Bay rough in July?
Usually not inside the bay. At NOAA's Cape Cleare buoy in the northern Gulf of Alaska, the daily maximum wave height averages 1.47 m in July, against 3.79 m in December. NOAA's Coast Pilot says seas of 20 feet (6.1 m) or more are unlikely from May through August, and gales are least likely in June, July and August. A cruise that crosses the Gulf can still be bumpy, so Major Marine Tours points seasick-prone guests to its half-day cruises that stay in protected waters.
Is Resurrection Bay rough in November?
November is the roughest month in the Gulf of Alaska south of Seward, according to the Coast Pilot. It says wave heights reach 20 feet (6.1 m) or more up to eight percent of the time, and gales are most likely in November and December. At the Cape Cleare buoy the daily maximum wave height averages 3.44 m in November. The bay is more protected, but the open water beyond Cape Resurrection is where those seas build.
Which Seward cruises stay in Resurrection Bay?
The half-day ones. The National Park Service says half-day tours stay in the more protected waters of Resurrection Bay, and Major Marine Tours describes its 4 hour wildlife cruise as exploring the calmer, protected waters of the bay. Its 6 hour and 8.5 hour cruises go out into the Gulf of Alaska.
Why is the Gulf of Alaska rough south of Seward?
NOAA's Coast Pilot says conditions there are often the roughest in the Gulf. A long fetch to the east and southeast lets sea and swell build up from that direction. It also calls the early part of winter the roughest part of a rough season.
Is the Resurrection Bay rough in winter?
Usually, yes. In a typical year, December, January and February are all rated rough. This is the typical pattern, not a forecast for any sailing.
