Late September in the western Algarve has a character all its own. The coast empties just enough for an evening beach walk to feel like a gift rather than a negotiation; the sea holds its warmth from the summer months; and the cultural calendar, rather than winding down, seems to gather itself for a final push. This week a genuinely significant concert lands in Lagoa, the fado series at Portimao's Antiga Lota introduces a new pair of fadistas, and the Amigos de Música classical music association opens its new year with two evenings in the hills. There is also practical news for anyone planning a trip: FlixBus is opening new connections into the region from Lisbon.

This week in the west

Invasive seaweed triggers beach cleanup across Portimao municipality

An accumulation of invasive Asian seaweed on beaches across the municipality of Portimao prompted an emergency response in the middle of the month, with Praia do Alemao among the most affected sites. The municipal water and waste company EMARP mobilised machines and crews to remove the material and minimise its effect on the beach areas, pledging to continue monitoring the coastline and intervening wherever the situation demands it. The seaweed is an invasive species that has troubled Algarve beaches repeatedly in recent years. Cleanup operations were under way last week and conditions at the south-coast Portimao beaches should be improving, but anyone planning a day at Praia da Rocha or neighbouring beaches would be wise to check local conditions before setting out. The beaches of Praia da Luz and the Lagos stretch to the west are not affected.

FlixBus to run Algarve coaches from Lisbon's Sete Rios from 29 September

FlixBus is extending its Algarve service with new routes departing from Lisbon's Sete Rios terminal from Tuesday 29 September, complementing the connections it already runs from Gare do Oriente in the east of the city. The move gives visitors from Lisbon a more central departure point when heading south to the Algarve, and adds further capacity to a corridor that is among the most popular long-distance bus routes in Portugal. The Portugal News reported the development on Sunday. Sete Rios is the main intercity coach terminus in Lisbon, easily reached by Metro, and the addition of an Algarve service there will be welcome news for anyone making the journey by coach rather than train or car.

Three new free exhibitions open at Lagos cultural spaces this week

The Centro Cultural de Lagos and the Armazem Regimental have each opened new shows this week that run into late September and beyond. "Between the Invisible and the Essential," a two-person exhibition by Joana Varatojo and Clara Buser, fills the upper gallery rooms of the cultural centre through Tuesday 29 September. At the Armazem Regimental, a few minutes' walk away in the historic quarter, Nelia Duarte's solo show "Here Come the Others" runs until Wednesday 30 September. A third exhibition at the cultural centre, "The Day Shapes Colour" by Karina Alves, opens a longer run through to mid-October. All three are free to visit. Visitors to Lagos old town this week can work in an exhibition visit alongside an evening stroll without any planning at all, which is one of the more satisfying things about a September afternoon in a place this size.

What's on this week

Amigos de Música opens new season, Os Agostos, Tuesday 22 and Thursday 24 September

The classical music association Amigos de Música launches its 2026/27 concert year with two performances at the Sitio dos Agostos venue in the hills of the Portimao hinterland. Berlin-based cellist Adele Bitter and pianist Holger Groschopp open the season, with concerts on Tuesday 22 and Thursday 24 September both beginning at 7pm. This is an intimate, membership-led classical music programme that has built a devoted following across the region over many years; the Agostos venue, a quinta in the countryside behind the coast, is one of the quieter discoveries the area offers. General reservations were open from 8 September and places are limited; contact details are on the Amigos de Musica website. The concerts run for roughly ninety minutes each.

12th Oktoberfest, Vila Vita Biergarten, Porches, Thursday 24 September

The Vila Vita Parc resort at Porches stages its 12th Oktoberfest in the hotel's gardens on Thursday 24 September, free to enter. This is a rather pleasant version of the format: an outdoor biergarten in the Lagoa countryside on a warm early-autumn evening, with the resort grounds providing an attractive setting that sits well apart from the marquee-and-trestle image of the original. Porches is on the N125 between Lagoa and Armacao de Pera, around 20 kilometres east of Lagos.

European Night of Researchers, Centro Ciencia Viva de Lagos, Friday 25 September

The annual European Night of Researchers lands at the science centre in Lagos on Friday 25 September from 5pm. On the same night across the continent, researchers and scientists step out of their institutions and into contact with the public through experiments, demonstrations, live science and conversations, and the Lagos edition sits naturally in a coastal setting where the marine and environmental sciences feel locally grounded rather than abstract. It is free and particularly good for families. The science centre is centrally located in Lagos old town and an early evening visit pairs well with dinner in the neighbourhood afterwards.

Ha Fado na Lota: Ana Marques and Joao Leote, Antiga Lota, Portimao, Saturday 26 September

The fourth concert in the Ha Fado na Lota series takes place at the Antiga Lota on the Arade riverfront in Portimao on Saturday evening at 9pm. This week the stage belongs to Ana Marques and João Leote, accompanied by Vítor do Carmo, Nuno Martins and José Santana. All concerts in the series are free. The restored fish market beside the river remains one of the most atmospheric open-air venues in the western Algarve, and September Saturday evenings there tend to be warm enough to sit outside without a jacket. The series continues every Saturday through 10 October; a companion exhibition on fado's history and its UNESCO inscription runs alongside at the Antiga Lota until mid-October. Portimao is 24 kilometres east of Lagos along the EN125.

Beto Kalulu: Uma Vida numa Noite, Centro de Congressos de Lagoa, Saturday 26 September

The biggest concert of the week, and arguably of the month, takes place on Saturday evening at the Congress Centre in Parchal, the riverside village that forms part of the Lagoa municipality. Veteran Carvoeiro musician Beto Kalulu performs "Uma Vida numa Noite" (A Life in One Night), a retrospective concert tracing his journey from Angola to the Algarve and across nearly five decades of music, from the 1970s to the present day. Sixteen musicians take the stage alongside him, with confirmed special guests including Rão Kião, Dany Silva, Fernando Girão and Gabriel de Rose. Tickets are 15 euros for the first seating section and 12 euros for the second, with a reduction for Cultural Passport holders, and are available online through Bilheteira Online and at CTT counters, Fnac and Worten. The Congress Centre at Parchal is on the south bank of the Arade river between Portimao and Lagoa town.

Coming up

Rallye Casinos do Algarve returns to western roads, Thursday 1 to Saturday 3 October

The Rallye Casinos do Algarve, the flagship round of the Portuguese Rally Championship, installs its service park and start and finish zones at the Parque Municipal de Feiras e Exposicoes in Lagoa from Thursday 1 October, with competitive stages on Friday 2 and Saturday 3 October. On Friday afternoon the action passes through the Lagos and Vila do Bispo areas; Saturday brings double passages through the Messines and Sao Marcos da Serra hills in the Silves municipality, a new stage in Santana da Serra across the border in Ourique, and a concluding City Stage in Portimao with the prize ceremony at 6pm. The rally crosses five municipalities in total: Lagoa, Lagos, Portimao, Silves and Ourique. For visitors based in the western Algarve the Lagos and Vila do Bispo stages on Friday afternoon offer the easiest access, and the service park in Lagoa is worth a visit for the team transport and preparation activity that fills the paddock on Thursday.

Ha Fado na Lota continues: Adriana Marques and Helder Coelho, Antiga Lota, Saturday 3 October

The Ha Fado na Lota series at Portimao's Antiga Lota runs for two more free Saturday evenings after this week, with Adriana Marques and Helder Coelho on Saturday 3 October and Luana Velasques and Cecilio Santos closing the programme on Saturday 10 October, both concerts at 9pm. The final fortnight of the series coincides with a quieter and particularly agreeable stretch of the year on the Arade waterfront. The companion exhibition on fado's history remains in place through to mid-October.

The week to turn your back on the sea

Nobody comes to the Algarve for the mountains. You come for the beaches, and quite right too, but all summer there's been a green wall standing quietly behind you while you stared at the blue, and this is the week to go and meet it.

The drive is the first pleasure. An hour or so from Luz, up through Portimão and onto the road that starts to climb, and somewhere among the eucalyptus and cork oaks the air through the window changes. It smells of trees instead of salt. By the time you reach Monchique town you've left the Algarve you know and arrived somewhere that feels a day's travel away rather than an hour.

The town itself asks nothing of you. Steep cobbled streets, a proper unhurried square, coffee that costs what coffee should cost, and a church doorway carved like knotted rope that has been surprising visitors for five hundred years. This is mountain-ham and chestnut country, not grilled-sardine country, and lunch up here tastes of it.

Then carry on up to Fóia, the roof of the Algarve at 902 metres. Here's the reason I'm sending you this week and not in August: in high summer the heat haze flattens that famous view into a milky guess. When the first cooler days arrive the air sharpens, and the whole coast lays itself out at your feet, Portimão to Lagos and, on the clearest days, all the way to the corner of the continent at Sagres. You've spent your week down there. It's worth seeing where you've been.

A word on medronho, because someone will offer you some. It's the local firewater, distilled from the fruit of the strawberry tree that grows all over these hillsides, and it is considerably stronger than its innocent orchard name suggests. A bottle from a proper shop is a lovely thing to take home. A third glass of somebody's homemade batch at lunchtime, when you still have a mountain road to drive down, is not. The honey, on the other hand, you can be as greedy about as you like.

On the way back, drop into Caldas de Monchique, the little spa hamlet tucked into a shaded valley below the town. People have been coming to its thermal springs since the Romans, and even if you don't take the waters it's a lovely cool half hour under the trees.

Take a layer, whatever the beach forecast says. It's genuinely cooler up there, which in late September is no longer a warning but a selling point.

And if you pass a man at the Fóia viewpoint pointing out Luz to nobody in particular, say good afternoon. It's probably me.

The week's weather

The week opens warm at around 30 degrees on Monday under clear skies and holds steady there through Tuesday and Wednesday. The second half of the week turns hotter rather than cooler: around 31 degrees on Thursday, a peak of around 34 on Friday, and around 33 on Saturday, before Sunday eases back to a fresher 28. No rain is expected on any day of the week. The sea remains warm and beach conditions are excellent throughout.
