Algarve in October: weather, sea temperature and what to do
October is the best value month in the Algarve: the sea is still 20°C, highs reach 24°C and prices are low season.
Why October is a special month in the Algarve
For many regular visitors, October is the Algarve’s best-kept calendar secret. Summer eases away slowly: the sea retains the heat it has built up over months, the beaches empty and accommodation prices drop to low-season levels. Those seeking sun without crowds find October to be the ideal window.
This guide answers the practical questions: can you still go for a swim? What weather should you expect? What to pack? And what to do when the day doesn’t call for the beach? For an overview of the whole season, see our Algarve autumn and winter guide.
Can you still go for a swim in October?
Yes, especially in the first half of the month. Sea water hovers around 20°C, the highest temperature you will find outside summer, because the ocean takes months to cool down. With highs around 24°C and generally moderate wind, a beach day in October is perfectly realistic.
In the second half the weather becomes less predictable: sunny days still dominate, but the chance of rain increases and evenings cool earlier. The rule of thumb is simple: the earlier in the month, the more beach days.
October weather in numbers
| Indicator | Typical value |
|---|---|
| Maximum temperature | about 24°C |
| Minimum temperature | about 17°C |
| Sea water | about 20°C |
| Sunshine | about 8 hours per day |
| Rainy days | 6 to 8 in the month |
These figures are averages: some Octobers are almost summer-like, others see autumn arrive earlier. For the forecast for the week of your trip, check our Algarve weather by zone page.
Crowds and prices
October marks the end of the high season. The beaches that in August fill up by mid-morning now have plenty of space, parking ceases to be a problem and restaurant tables appear without queuing. In accommodation, the difference is even more visible: prices fall sharply compared with August and September, with many hotels moving into low-season rates.

What to do in October
Beach
Still on the cards, especially in the first half. The more sheltered beaches of the Barlavento, such as the coves of Lagos and the Carvoeiro area, keep good conditions even with the autumn wind. See our Algarve beaches guide to choose.
Surf
October opens the swell season on the western coast. Sagres and the beaches of the Costa Vicentina start to receive consistent swells, with water still mild enough for those in a wetsuit.
Walking
With summer heat fading, the coastal trails are at their best. The Seven Hanging Valleys route and the Via Algarviana become pleasant at any time of day. See the best trails in the Algarve.
Golf
The high season for golf begins: ideal temperatures and courses in excellent condition. See our Algarve golf guide.
Gastronomy and harvests
In the inland Algarve, October is harvest month and a time for food festivals. It’s a good moment to swap a beach day for a drive through the hill villages.
What to pack
October calls for a two-season suitcase: summer clothes for beach days, a warm layer for evenings that cool to 17°C, and a light windbreaker or waterproof for rainy days. Comfortable footwear makes a difference if you plan to hike. Sunscreen remains necessary: the October sun in the Algarve still burns.
September and November compared
September is warmer and more expensive, with the sea at its yearly peak, but still quite busy. November is clearly low season: the sea drops to 18°C, rain becomes more frequent and some beach facilities close. October sits in the middle, and that is exactly what makes it attractive: late-summer weather with low-season prices and tranquillity.
