Monterey Bay offers excellent year-round whale watching. However, the deep submarine canyon creates ocean swells that can trigger motion sickness. Preparing before you reach the dock is the best way to ensure you enjoy the wildlife.
When should I take motion sickness medication?
Take motion sickness medication 30 to 60 minutes before your boat departs.
Medication needs time to enter your system before the boat hits ocean swells. Taking pills after you feel sick is rarely effective. Check your tour departure time and plan accordingly.
Where is the best place to stand on the boat?
Stand outside on the lower deck in the fresh air.
Fresh ocean breezes help reduce nausea. Avoid the indoor cabins, as enclosed spaces make motion sickness worse. Try to stay near the middle of the boat where the rocking is least noticeable.

Where should I look to prevent seasickness whale watching?
Keep your eyes focused on the fixed horizon.
Looking at a stable point helps your brain reconcile the movement of the boat. Do not look down at your phone or read a book. Keep your camera down until you actually spot marine life.
How does clothing affect motion sickness?
Being too cold or too hot can increase nausea.
Ocean temperatures fluctuate significantly in Monterey Bay. Wear warm layers and bring a windproof and waterproof jacket. If you feel too warm, remove a layer to cool down.

What should I eat before the tour?
Eat light, simple snacks and drink bottled water.
Bring crackers or other plain foods to settle your stomach. Avoid heavy, greasy meals before your trip. Hydration is important, so keep bottled water on hand.
Does boat size matter for seasickness?
Larger boats generally offer a more stable ride in rough water.
Monterey tour vessels range from 53 feet to 110 feet long. Larger vessels handle ocean swells better. Smaller boats can mean a rougher ride, which increases the chance of motion sickness.
| Boat Size | Vessel Length | Ride Stability |
|---|---|---|
| Smaller vessels | Around 50 to 70 feet | More susceptible to ocean swells |
| Larger vessels | 100 to 110 feet | More stable in rough water |

Questions travellers ask
Do boats sell seasickness medication onboard?
No, tour operators typically do not sell medication onboard. You must bring your own motion sickness medication and take it 30 to 60 minutes before boarding.
How long are the Monterey whale watching tours?
Standard whale watching tours last between 2.5 and 4 hours. If you are prone to severe motion sickness, choose a shorter tour.
Are there restrooms on the boats?
Yes, tour boats operating out of Old Fisherman's Wharf feature onboard restrooms. However, the enclosed space can worsen nausea, so minimize your time inside.
