September in Tenerife is what many locals call the “Second Summer.” It is often the warmest month for sea temperatures, and with the major UK school crowds heading home, the island transforms into a more relaxed, sophisticated, and incredibly sun-drenched paradise. For an all-inclusive holiday, September is the ultimate “smart” choice for 2026. Tenerife
Warm Seas and Golden Evenings September is arguably the best month for swimmers. After a full summer of baking under the Atlantic sun, the ocean reaches its peak temperature of around 23°C to 24°C. The air remains hot, with average highs of 27°C to 29°C, but the humidity is manageable and the evenings are balmy enough to leave the cardigan in your suitcase.
The “Peace & Quiet” Couples: As soon as the school bells ring in the UK, the “family-heavy” atmosphere of August disappears. September is the prime time for adults who want a quieter pool, a faster bar service, and a more romantic vibe.
The Food & Drink Connoisseurs: September is a big month for the Canarian vineyards. If you’re staying at an all-inclusive with a focus on local produce (like Barceló Tenerife), you’ll likely see a heavy influence of the autumn harvest on the menus.
Music & Festival Fans: From the Phe Festival in Puerto de la Cruz to the Centreforce Tenerife Weekender (Sept 25th–28th, 2026), September is packed with events for those who like their sun with a side of rhythm.
The Best Water Temperatures: If you want to spend your “all-inclusive” time doing more than just looking at the water, September is the month. Whether it’s snorkelling, diving, or just bobbing in the sea, the Atlantic is at its most inviting.
Mellow Evenings: In September, the sun sets around 8 PM. It’s that perfect “golden hour” for inclusive cocktails on a terrace before dinner. The evening temperature stays at a beautiful 21°C, so outdoor dining is a must.
Better Resort Access: Because the capacity drops slightly compared to August, you’ll find it much easier to book the specialty à la carte restaurants that are part of your all-inclusive package.
Top Tip: September is the month of the Fiestas del Santísimo Cristo in La Laguna (Tenerife’s former capital). While your resort might be in the sunny South, it is well worth taking a day trip to the North to see the incredible firework displays and traditional processions that take place throughout the month.
The “Back-to-School” Drop: Prices for all-inclusive packages often drop by 25% to 30% the moment the UK schools return in early September.
Check the “Tenerife Weekender” Dates: If you aren’t a fan of house music and dance parties, avoid the final weekend of September in Playa de las Américas, as the Centreforce crowds will make the area very busy.
Go North for Value: Puerto de la Cruz is stunning in September. It’s less likely to have the “winter” clouds than in the later months, and all-inclusive rates here are significantly lower than in Costa Adeje.
Phe Festival (Sept 4-5, 2026): Head to Puerto de la Cruz for this eco-friendly indie music and culture festival. It’s a great mix of live bands, art, and “Canarian cool.”
Hiking the “Barranco del Infierno”: Now that the August heat has slightly mellowed, September is a great time for the “Hell’s Ravine” hike in Adeje. You’ll need to book your permit in advance!
Whale Watching: The sea is at its calmest in September, which means you get the best visibility for spotting the resident pilot whales and dolphins without the choppy winter waves.
For the absolute bargain: September 7th – September 21st, 2026. For the party vibe: September 25th – 28th, 2026 (The Centreforce Weekender).
Flights are plentiful from all major UK airports. The 4.5-hour journey lands you at Tenerife South (TFS), and because the summer peak is over, the airport experience is usually much smoother and faster.
