Anacortes Whale Watching: What Time of Year Has the Most Sightings?

One of the most common questions visitors ask when planning a whale watching trip is simple:

What time of year offers the most sightings?

The short answer is that whale watching in Anacortes is productive from spring through fall, with June through September generally offering the strongest opportunities for encountering whales and other marine wildlife.

However, the best time to visit depends on what you're hoping to see and the type of experience you're looking for.

The Short Answer

For most visitors, June through September offers the best combination of:

• Whale activity

• Weather conditions

• Daylight hours

• Tour availability

These months consistently attract travelers from around the world to the Salish Sea and San Juan Islands region.

Why Anacortes Is Such a Strong Whale Watching Departure Point

Season matters, but location matters too.

Anacortes sits at the gateway to the Salish Sea, providing fast access to productive whale habitat without requiring visitors to take a ferry.

Compared to departures farther south, boats leaving from Anacortes can often spend less time traveling and more time focused on wildlife.

For visitors making a dedicated whale watching trip, that advantage can be significant.

Month-by-Month Whale Watching in Anacortes

March–May

Spring marks the beginning of increased wildlife activity throughout the region.

Visitors may encounter:

• Bigg's (transient) orcas

• Humpback whales

• Harbor porpoises

• Seals and sea lions

• Bald eagles

Crowds are generally smaller than summer, making spring an attractive option for travelers who prefer a quieter experience.

June

June marks the start of peak whale watching season.

Longer daylight hours, improving weather, and increased wildlife activity make it one of the most popular months for whale watching in Anacortes.

July

July is traditionally one of the busiest months for whale watching.

Visitors benefit from:

• Warm weather

• Long daylight hours

• Frequent departures

• Excellent wildlife viewing opportunities

Because demand is high, advance reservations are strongly recommended.

August

August continues the strong wildlife viewing that begins in July.

For many visitors, this is one of the easiest months to plan around thanks to stable weather and frequent tour schedules.

September

Many experienced whale watchers consider September one of the best months of the year.

Benefits include:

• Continued whale activity

• Pleasant weather

• Smaller crowds after Labor Day

• Excellent overall conditions

For travelers seeking a balance between sightings and crowd levels, September is often an excellent choice.

October

October can still provide strong whale watching opportunities while offering a quieter experience than peak summer months.

November–February

Whale watching continues throughout the winter, although weather conditions become more variable and tour schedules are typically reduced.

Winter trips are often best suited for dedicated wildlife enthusiasts rather than first-time visitors.

When Should You Book the Orca-Only Tour?

If your primary goal is seeing orcas, June through September is typically the most popular period for booking Outer Island Excursions' Orca-Only Tour.

This dedicated experience was designed specifically for guests who want to focus on finding orcas in the Salish Sea.

Outer Island Excursions was the original company to introduce an orca-specific guarantee and remains one of the few operators offering one today.

For many visitors, this has become one of the most compelling reasons to choose Anacortes for whale watching.

Why the Guaranteed Orca Tour Operates in the Afternoon

Many visitors assume that morning tours automatically provide the best chance of seeing whales.

When it comes to locating orcas, that is not necessarily true.

Orcas can travel more than 100 miles in a single day, making their morning location difficult to predict.

As the day progresses, whale watching operators gather sightings and track whale movements throughout the Salish Sea. By the afternoon, captains often have significantly more information available about where whales are traveling.

This is one reason Outer Island Excursions schedules its Guaranteed Orca Tour in the afternoon.

The additional information gathered throughout the day helps improve efficiency when locating orcas and supports the company's industry-leading orca guarantee.

When Should You Book?

Peak Season (July–August)

Book at least 4–6 weeks in advance, especially for weekends and holidays.

Shoulder Season (May, June, September, October)

More flexibility is often available, though popular dates still fill quickly.

Winter

Reservations are generally easier to secure, but departures may be weather dependent.

Final Thoughts

If your goal is maximizing whale watching opportunities, June through September remains the strongest overall window for visiting Anacortes.

However, every season offers unique wildlife encounters.

For visitors specifically hoping to see orcas, Outer Island Excursions' Orca-Only Tour combines the advantages of Anacortes' location, real-time whale tracking, afternoon departures, and the original orca-specific guarantee to create one of the most focused whale watching experiences in Washington.
