What to Wear Whale Watching in the Pacific Northwest: The Complete Layering Guide for Every Season

One of the most common questions guests ask before their trip is simple: What should I wear whale watching?

The answer surprises many first-time visitors.

Even on a warm summer afternoon, conditions on the Salish Sea are often much cooler than they are on land. Wind, ocean spray, and changing weather can make it feel 10–15°F colder once you're out on the water.

Fortunately, staying comfortable is easy if you dress in layers.

Here's everything you need to know before your whale watching adventure.

The Golden Rule: Dress in Layers

Instead of wearing one heavy jacket, choose several lighter layers.

Layering allows you to stay warm during cool parts of the trip while giving you the flexibility to remove clothing if the sun comes out.

A simple three-layer system works well for almost every whale watching tour.

• Base layer to manage moisture

• Mid-layer for warmth

• Outer layer to block wind and water

This combination keeps you comfortable throughout changing conditions.

Summer Whale Watching (June–September)

Summer is the busiest whale watching season, but don't expect beach weather on the water.

Base Layer

• Lightweight moisture-wicking T-shirt or long-sleeve shirt

• Synthetic fabrics or merino wool work well

Mid Layer

• Light fleece or pullover

• Thin insulated jacket if you get cold easily

Outer Layer

• Windproof or water-resistant jacket

• Lightweight rain shell if showers are possible

Bottoms

• Comfortable long pants

• Lightweight hiking pants or jeans work well

Although temperatures may be warm on shore, shorts can become uncomfortable once the boat is moving.

Spring and Fall (March–May & October)

These seasons often bring changing weather throughout the day.

Base Layer

• Long-sleeve moisture-wicking shirt

• Merino wool or synthetic fabric

Mid Layer

• Warm fleece

• Light insulated jacket

Outer Layer

• Waterproof rain jacket

• Windproof shell

Bottoms

• Long pants

• Waterproof pants are helpful on rainy days

Spring and fall tours often begin cool and warm up later, making layering especially important.

Winter Whale Watching (November–February)

Winter tours require more preparation because temperatures and wind chill can be much lower.

Base Layer

• Thermal base layer

• Merino wool or synthetic materials

Mid Layer

• Heavy fleece

• Insulated jacket

Outer Layer

• Waterproof winter shell

• Windproof jacket

Bottoms

• Thermal leggings under pants

• Warm waterproof footwear

Don't forget warm gloves and a hat that covers your ears.

Footwear Matters

Boat decks can become wet from ocean spray, so good footwear is important.

The best choices include:

• Athletic shoes with good grip

• Hiking shoes

• Waterproof boots in cooler weather

Avoid:

• Flip-flops

• Sandals

• High heels

• Shoes with slippery soles

Closed-toe shoes provide the best comfort and safety.

Don't Forget These Essentials

A few small items make a big difference during your trip.

Bring:

• Sunglasses

• Sunscreen

• Hat or baseball cap

• Camera or binoculars

• Water bottle

• Small snack

• Motion sickness medication if needed

Even on cloudy days, sunlight reflecting off the water can be surprisingly strong.

What NOT to Wear

Certain clothing tends to make whale watching less enjoyable.

Avoid:

• Heavy cotton layers in cool weather

• Flip-flops or sandals

• Clothing that restricts movement

• Loose scarves that can blow around in the wind

• Expensive jewelry that could be lost overboard

Comfort is far more important than fashion on the water.

What About Kids?

Children usually become cold faster than adults.

Dress them in one extra layer compared to what you're wearing, and bring:

• Spare clothing

• Extra socks

• Hat

• Gloves during cooler months

• Favorite snacks

Keeping children warm goes a long way toward making the trip enjoyable for everyone.

Photography Tips

If you're bringing a camera, keep it somewhere easily accessible.

You'll often have only a few seconds to capture wildlife before it surfaces again.

If temperatures are cool, consider lightweight gloves that still allow you to operate camera controls comfortably.

Motion Sickness Tips

Loose, comfortable clothing can help you feel more comfortable on the water.

If you're prone to seasickness:

• Take medication before boarding, following package directions.

• Stay outside whenever possible.

• Look toward the horizon instead of down at your phone.

• Stay hydrated.

Many guests find fresh air on deck more comfortable than sitting inside.

One Last Packing Tip

A simple rule works almost every time:

Wear one more layer than you think you'll need, and bring one extra layer in your bag.

It's always easier to remove clothing than to wish you'd packed another jacket.
