Whale Watching in Tenerife in September: What Changes (and What Doesn't) at the End of Summer

When summer comes to an end in the rest of Europe, first-time visitors to Tenerife often expect to find an island ready to slow down. Independent travelers who choose September for their stay instead discover one of the best times of the year to experience the south of the island: temperatures that are still fully summer-like, less crowded beaches, and above all, a sea that does not follow the school holiday calendar.

One of the questions we are asked most often by those planning a trip in September concerns whale watching itself. Does it make sense to go out on a boat now? Are the cetaceans still there or do they leave the island? The short answer is simple: in the channel between Tenerife and La Gomera there is no migratory season for pilot whales and bottlenose dolphins, because here they are not visiting guests but permanent residents.

Why September Is a Special Month to Head Out to Sea

September in Tenerife offers a climatic balance that is hard to find in other months. The sultry heat of July and August gives way to stable days, with temperatures comfortably hovering between 26 and 28 degrees on the coast and an Atlantic that has absorbed all the warmth of the summer sun, making it ideal for boat trips. Departing from Puerto Colón with our dolphin and whale watching catamaran, sea conditions in September often provide extraordinarily calm days, perfect for sailing unhurriedly toward the channel.

The figures explaining why whale watching works 365 days a year here do not change in September: around 500 resident pilot whales and hundreds of bottlenose dolphins continue to populate the deep waters between the two islands, where the seabed drops to over two thousand metres, guaranteeing abundant food in every season. The sighting rate remains above 99% of outings, exactly as in the dead of winter or summer.

What really changes in September is the experience on board and ashore. The docks at Puerto Colón are less hectic compared to July and August, allowing for more relaxed organization and even more personal attention during boarding. Those who choose to rent a car to explore the south of the island or look for a quiet accommodation between Costa Adeje and Palm Mar will also find September to be the ideal time to move around with greater freedom.

For those visiting Tenerife for the first time and wanting to combine a boat trip with independent exploration of the island, September makes it possible to alternate catamaran outings with days dedicated to routes toward Teide or the quieter coves along the coast without the pressure of mass tourism.

Practical Tips for Those Traveling in September

If you are organizing your trip for this period, here are three practical pointers we always share with our guests:

• Book with a little margin: even though September is less chaotic than August, spots on capacity-controlled catamarans still fill up on the calmest sea days.
• Bring adequate sun protection: the southern sun does not lose intensity just because the official summer is ending; the UV index remains high.
• Enjoy the local rhythm: with days still long and bright, a morning half-day at sea leaves plenty of time to explore the rest of the island in the afternoon.

The sea off Tenerife in September does not notice that other people's holidays are over. If you are on the island during this period, stepping aboard remains one of the best choices you can make.
