What September is like in the Algarve
September is many people's favorite Algarve month. Highs sit near 80F (27C), and the sea is at its warmest of the year. Crowds fade after the first week as schools restart. Everything is still open, and prices come down a bit. Days are still long and hot, but evenings turn pleasantly mild. Lifeguards are usually still on the major beaches through the month.
It suits couples, homeschool families, and anyone who wants warm water and easy beaches. There is little reason to choose another month for a beach trip. If you want cooler weather for hiking, October or March is better.
Make the most of September
What is especially good about the Algarve this month.
The warmest sea of the year
September water is the most comfortable of the year for swimming and snorkeling.
Space on the beaches
After the first week, beaches thin out, and you can find quiet coves again.
Boat trips in calm seas
Late summer seas are often calm, making cave tours and Ponta da Piedade boat trips smooth.
What to pack for September
- Swimsuits and snorkel gear
- Sunscreen and a hat
- Water shoes
- A light layer for breezy evenings

Things to do in the Algarve
Ponta da Piedade, Lagos
Rock pillars, arches, and grottoes best seen by small boat or kayak in calm morning water.
Benagil sea cave
The famous cave with a hole in the roof. Boat and kayak tours run most of the year; access rules for landing inside have tightened, so check current regulations.
Seven Hanging Valleys Trail
A clifftop walk from Praia da Marinha toward Benagil and beyond. Best in spring and autumn, early in the day.
Sagres and Cape St. Vincent
The windswept southwestern tip of Europe, with a clifftop fortress and famous sunsets.
Ria Formosa Natural Park
Lagoons and barrier-island beaches reachable by ferry from Olhao, Faro, and Tavira. Superb for birdwatching.
Tavira
A calmer, more traditional town in the east, with a Roman-style bridge and ferries to Ilha de Tavira beaches.
Beat the crowds
- Take Ponta da Piedade and Benagil boat tours at the first departure of the day for calm water and fewer boats.
- Swap the busiest central beaches for the Ria Formosa islands or the west coast beaches, which are wilder and far less crowded.
- If you must go in July or August, book cars, villas, and popular restaurant tables early, and hit the beach by 9am.
- Stay in towns like Tavira or Lagos rather than high-rise resort strips for more character and quieter evenings outside peak season.
Know before you go
- Many beach bars, seasonal restaurants, and some hotels in resort areas close from about November to March. Larger towns stay open all year.
- Boat tours to the caves run much of the year but are frequently cancelled when seas are rough, especially in winter.
- Lifeguards typically staff major beaches from about June to September only; outside that window, check flags and conditions carefully.
- Some beaches along the cliffs are closed or restricted because of rockfall risk. Respect signs and do not sit directly below cliffs.
