How to Prevent Seasickness Before Fishing

The first few minutes after leaving Samara Beach can feel exciting: the shoreline opens up, the Pacific gets bigger, and everyone starts looking for the first sign of fish. But if you are prone to motion sickness, the best time to prevent seasickness before fishing is not once the boat is rolling offshore. It is the night before and the hour before departure.

Seasickness can affect experienced anglers as easily as first-time guests. It is not a sign that you are not adventurous or that you cannot handle a fishing trip. It is simply your brain receiving mixed signals from your eyes and inner ear. The good news is that a little preparation makes a major difference, especially on a private charter where our crew can help tailor the day around your group.

Start Preparing the Night Before

A successful fishing morning starts with sleep. Go easy on late-night cocktails, rich food, and anything that leaves you dehydrated or tired. Vacation schedules can be full, but a good night's rest gives your body a much better chance of adapting to the movement of the boat.

Drink water throughout the evening and again when you wake up. Costa Rica's warm coastal weather can make dehydration sneak up on travelers, particularly after a day at the beach, a long drive, or a few drinks at dinner. Dehydration does not cause seasickness by itself, but it can make nausea, headaches, and fatigue feel much worse.

If you know you get motion sickness, make your medication plan before the morning of the trip. Some over-the-counter motion sickness medicines work best when taken in advance, often 30 to 60 minutes before departure. Others can cause drowsiness, dry mouth, or blurred focus, which may not suit every guest. Read the label carefully and speak with a doctor or pharmacist ahead of travel if you have medical conditions, take prescription medication, are pregnant, or are choosing medicine for a child.

Scopolamine patches are another option some travelers use, but they require a prescription in the United States and are not right for everyone. Do not try a new medication for the first time just before a full-day offshore trip if you can avoid it. Knowing how your body responds is part of arriving ready to enjoy the water.

Eat the Right Breakfast, Not No Breakfast

Skipping breakfast seems logical when you are worried about nausea, but an empty stomach can make many people feel worse. The better move is a small, familiar meal that is easy to digest. Think toast, crackers, oatmeal, a banana, plain eggs, or yogurt if dairy normally agrees with you.

Avoid a heavy, greasy breakfast and limit very spicy foods. A big plate of fried food may sound appealing after an early wake-up, but it can sit poorly once the boat begins moving. The same goes for large amounts of coffee. One cup may be fine if that is your regular routine, but several strong coffees on an empty stomach can bring on jitters, dehydration, and stomach discomfort.

Bring simple snacks for the boat, particularly for longer charters. Dry crackers, pretzels, fruit, and ginger candies work well for many guests. Ginger can be soothing for mild nausea, though it should not be treated as a replacement for medication if you regularly get severe motion sickness. Small bites and regular sips of water are generally easier on the stomach than waiting until you feel hungry or thirsty.

Choose the Right Trip for Your Group

Trip length matters when you are deciding how to prevent seasickness before fishing. A half-day inshore trip can be a great introduction for first-time anglers, families with younger guests, or anyone uncertain about how they will feel on the ocean. The ride is often shorter than a dedicated offshore run, and the day still offers plenty of action and beautiful Pacific scenery.

That does not mean offshore fishing is only for people with iron stomachs. Many guests feel perfectly comfortable on a full-day adventure, especially when conditions are calm and they prepare well. Offshore trips offer more time to reach productive waters and pursue species that draw serious anglers to Costa Rica. The trade-off is that longer runs can mean more exposure to swell, sun, and boat movement.

When booking, be honest about your group's experience. Let the captain know if someone has been seasick before, if children are joining, or if your group would rather prioritize a shorter ride. Samara Deep Sea Fishing offers several charter lengths and boats, so the crew can help you choose an outing that fits your vacation plans and comfort level.

Once on the Water, Look Up and Stay Outside

Fresh air and a clear view of the horizon are two of the most useful non-medication tools for managing motion sickness. If you start to feel off, move outside rather than sitting in an enclosed cabin. Keep your eyes on the distant horizon, not on the deck moving beneath your feet or a phone screen in your hands.

This is one reason fishing guests should put the camera down during the ride out. A few photos are great, but reading, scrolling, editing video, or staring at a map below deck can intensify the mismatch between what your eyes see and what your body feels. Save the close-up photos for the catch.

Position can help, too. The center of the boat usually has less motion than the bow or stern, and staying low and near the middle can be more comfortable when the water is choppy. Your captain and mate know the boat and current conditions, so ask where they recommend you sit or stand. It is a simple question that can improve the whole trip.

Try not to lie down in a cramped space if nausea begins. For some people, reclining in fresh air helps. For others, lying down makes the sensation worse. Stay upright, breathe slowly, look outward, and tell the crew early. There is no prize for quietly toughing it out until you feel miserable.

Dress for Sun, Spray, and Changing Conditions

Feeling too hot, cold, wet, or sunburned can make motion sickness harder to manage. Wear lightweight layers, even on a warm Costa Rica morning. A breathable long-sleeve shirt protects against the sun, while a light jacket can be welcome during an early run or after a splash of spray.

Choose non-slip footwear and keep your hat secure. A hat with a chin strap is helpful when the wind picks up. Polarized sunglasses reduce glare and can make it easier to focus on the horizon, though guests who already feel dizzy may prefer to remove them briefly if the visual effect is uncomfortable.

Sunscreen is also part of your seasickness strategy. Strong sun and heat can drain your energy quickly. Apply it before departure and reapply as needed, especially on a full-day charter. Feeling physically comfortable lets you focus on the bite instead of every bump in the water.

Trust the Crew and Speak Up Early

Local captains watch the weather, wind, swell, and fishing conditions every day. If the forecast calls for rougher water, they can explain what that may mean for the ride and help set realistic expectations. Ocean conditions are never guaranteed, and even calm mornings can change, but a professional crew plans around safety and comfort as well as fishing.

Tell your mate at the first sign of nausea, not after you have reached the point of vomiting. They may suggest a better place to sit, offer water, help you get fresh air, or adjust the plan where practical. On a private charter, the day is about your group. Communication helps the crew create the best possible experience within the conditions.

If someone does get sick, do not let it end the adventure in their mind. Seasickness often comes in waves, and many guests feel noticeably better after a little time outside, hydration, and a change of position. Others may prefer to rest while the rest of the group keeps fishing. Either way, the crew has seen it before and will handle it without judgment.

A Simple Pre-Departure Checklist

Before leaving for the marina, make sure each guest has slept, eaten a light breakfast, and started hydrating. Bring a water bottle, easy snacks, sunscreen, a hat, sunglasses, and a light layer. If you use motion sickness medicine, take it according to its directions early enough to work before the boat leaves shore.

Most of all, arrive with a relaxed plan. Watch the horizon on the ride out, listen to the captain, and give yourself permission to say something the moment you feel uncomfortable. A few smart choices before departure can leave more room for the moments you came for: the first strike, the bright flash of a fish near the boat, and a Costa Rica fishing story your group will keep telling long after the salt has dried.
