When is the best time to visit the Algarve?
For most travellers, the best time is the shoulder season — May, June and September. You get the best balance of warm weather, a pleasant sea, beaches with room to spare and prices much lower than at the August peak. June and September are perhaps the two best months of the year: the sea is already (or still) warm, the sun is reliable and yet the August crowd is missing.
| Season | Months | Climate | Crowds | Prices |
|---|---|---|---|---|
| High (peak) | Jul–Aug | Hot, 28 °C, guaranteed sun | Very high | The highest of the year |
| High (shoulder) | Jun and Sep | Warm, 26 °C, good sea | Medium-high | High, below Aug |
| Mid | Apr, May, Oct | Mild, 20–23 °C | Low-medium | Moderate |
| Low | Nov–Mar | Mild, 16–19 °C, some rain | Low | The lowest (ideal for long stays) |
Whatever the month, there are villas and apartments to rent with direct booking on Homing. See also where to stay in the Algarve.
The Algarve climate month by month
The Algarve has more than 300 days of sun a year and one of the mildest climates in Europe. In summer (June to September) highs hover around 26–28 °C and it barely rains; in winter (December to February) it stays mild, with 16–17 °C by day and cool nights. Spring and autumn are bright and comfortable. This chart shows the average air and sea temperature through the year.
Note the sea temperature: it only turns truly inviting from June to October (20–22 °C). In May the water is still cool (~18 °C), more for a quick dip than long swims — especially in the Barlavento, where the water is a few degrees cooler than in the Sotavento.
High, mid and low season: prices and crowds
The difference in price and atmosphere between seasons is huge. In August, the whole Algarve is full and accommodation prices can be 2 to 3 times those of winter. In June and September you get practically the same weather for a good deal less. From November to March, outside New Year, it is the cheapest and quietest time — perfect for remote work, golf or long stays.
To understand in depth how prices vary by area, house type and season, see our guide to how much it costs to rent a holiday home in the Algarve. For winter, the guide to the Algarve out of season; and for the year-end, New Year in the Algarve.
Best month for your travel profile
Families with children: June and early September — a warm sea, long days and fewer people than in August. Couples: May, June or October, for quiet and better prices. Surf: autumn and winter (September to March), when the Atlantic swell is bigger on the west coast and at Sagres. Golf: spring and autumn (March–May, October–November), with ideal temperatures to play. Quiet and budget: from November to February, outside New Year.
To choose the right area too, cross-reference the season with the best areas for families and the comparison of Barlavento or Sotavento.
Events and festivals in the Algarve through the year
There is always something happening in the Algarve, and choosing the month around the right festival can change the trip. These are some of the best-known recurring events — always confirm the exact dates for each year with the organiser or the council.
| Time | Event | Where |
|---|---|---|
| February | Carnaval de Loulé | Loulé |
| June | Santos Populares (Santo António, São João) | Across the region |
| July | Festival da Sardinha | Portimão |
| July | MED Festival (world music) | Loulé |
| Aug | Festa da Ria Formosa (seafood) | Olhão |
| September | Festival F | Faro |
| October | Food festivals and grape harvests | Various |
| 31 December | New Year and fireworks | Albufeira, Portimão, Vilamoura |
If the idea is to see in the new year in the region, check the dedicated guide to New Year in the Algarve, with the towns, the fireworks and when to book.
When to book to catch the best prices
The rule is simple: the earlier, the better, especially for the most in-demand dates. For July, August and New Year, book 2 to 4 months ahead — the best houses, especially villas with a pool, sell out first. For the shoulder season and winter there is more flexibility and, at times, good last-minute deals.
Booking direct on Homing is usually cheaper than on Airbnb or Booking, because there is no platform commission. Open the listing for any house to see the real price for your dates, with no hidden fees.
