In September, Corfu town smells of grilled fish and fresh bread drifting out of the lanes of the Old Town, and the arcades of the Liston fill with people lingering over a last coffee. The sea still holds the warmth of summer while the days begin to shorten, and the island’s olive groves and vineyards turn toward the harvest.
What is the weather like in Corfu in September?
September in Corfu is still warm and summery, with the first real rain of the autumn starting to show up. At Aktion, on the mainland coast south-east of Corfu, highs average 81.0°F and lows 65.8°F, so the days stay hot while the nights begin to cool.
| Month | Average high (°F) | Average low (°F) | Precipitation (in) | Days with 1 mm or more of precipitation | Daylight on the 15th | Sea (°F) |
|---|---|---|---|---|---|---|
| August | 87.6 | 71.1 | 0.81 | 3.1 | 13 h 43 min | 81.7 |
| September | 81.0 | 65.8 | 4.33 | 8.4 | 12 h 23 min | 80.1 |
| October | 73.9 | 60.3 | 5.53 | 9.6 | 11 h 04 min | 75.0 |
The rain is the biggest change from the height of summer. August is nearly dry, while September brings rain on roughly one day in four, enough that a light rain jacket earns its place in the bag. The gray days are good ones for the museums of Corfu town, and the sunny ones are for the water.
With highs in the low 80s, sun protection still matters on the Old Fortress ramparts and on the beaches, and a hat is welcome on any walk in the open. Lows in the mid-60s call for a light layer once the sun is down.
The light is shifting too. The day is now barely longer than the night, so dinner on a taverna terrace comes with a sunset that arrives noticeably earlier than it did a month ago. The sea, near 80 degrees, remains a real attraction of the month.
Can you swim in Corfu in September?
Yes, the sea is warm enough for a long, unhurried swim, with the surface near Corfu averaging 80.1°F. It is only a little cooler than in August, so the summer habit of a swim before lunch and another before dinner still works.
Corfu is an island with a lot of shoreline. Its northeastern edge faces the coast of Sarandë in Albania across a strait, and its southeast side looks toward the mainland coast of Thesprotia. The Achilleion palace has a panoramic view of the town to the north and the southern part of the island, framed by the Ionian Sea to the east, and it gives a sense of how much coast there is to choose from.
Between swims, the sea is part of the scenery of the town itself. The Old Fortress stands in the city of Corfu at the water’s edge, and a walk around it shows the sea you are about to get into. Pack a swimsuit and a towel, and plan the sightseeing around the water rather than the other way round.
What to do in Corfu in September
September in Corfu is about slowing down. The sea is warm, the town is pleasant to walk in, and the island’s wine and olive country is entering its busiest season of the year. Corfu is mostly planted with olive groves and vineyards and has been producing olive oil and wine since antiquity, so the landscape itself is the main attraction of the month.
At the table, the island has its own grapes. The local wine varieties include the white Kakotrýgēs and the red Petrokóritho, along with Robóla, Moscháto (white muscat) and Mavrodáphnē. A glass of one of the whites with grilled fish on the waterfront is a good way to spend an evening, and the vineyards are picking grapes in the weeks around now.
Corfu also has a sweet side. Modern growers have introduced kumquat and bergamot orange, which end up in spoon sweets and liqueurs. A small jar of kumquat preserves or a glass of the liqueur is the souvenir to look for.
The Old Town and the Old Fortress
The Old Town of Corfu was inscribed on the UNESCO World Heritage List in 2007, and walking its lanes is the first thing to do. Tall old houses, laundry lines, small churches and cafés open onto the arcades and squares, and the whole place is arranged for wandering without a map.
The Old Fortress is a Venetian fortress in the city of Corfu. From its walls you look across to the town on one side and the sea on the other, and September’s warm air makes the climb pleasant rather than punishing. Wear shoes with a decent grip for the stone ramps.
Museums for the gray days
The Archaeological Museum in Corfu city houses the Gorgon pediment from the Temple of Artemis in the ancient city of Korkyra, excavated at Palaiopolis in the early 20th century. It is the museum to choose if a September shower interrupts the plan.
The Museum of Asian Art of Corfu is at the Palace of St. Michael and St. George and holds over 12,000 artifacts in 15 rooms. Its collection feels far from the Ionian, which is the point. Another small stop is the Banknote Museum in Aghios Spyridon square, with a complete collection of Greek banknotes from independence to the adoption of the euro in 2002.
The Ionian Academy, the first academic institution of modern Greece, was established by the French during their administration of the island as the département of Corcyre. Its building was bombed in the Second World War and is now fully restored.
Ancient Korkyra and the Achilleion
The ruins of ancient Korkyra, called Palaiopolis, lie in the city of Corfu at the site of the palace of Mon Repos, which was built on top of them. It is a place for a wander among stones and trees.
Kardaki Temple stands on Analipsi Hill in what was ancient Korkyra. It is an Archaic Doric temple built around 500 BC and is considered the only Doric Greek temple without a frieze.
The Achilleion is the reason to leave the town for a while. Its panoramic view takes in the city of Corfu to the north and the southern part of the island, with the Ionian Sea to the east.
A two-day itinerary for Corfu in September
Day 1 is the town. Begin with the Old Town lanes and the arcades for coffee, then climb the Old Fortress while the day is still warm. Move on to Aghios Spyridon square and the Banknote Museum, then sit down to a long lunch in a taverna, with grilled fish and a glass of local white wine.
After lunch, head for the Archaeological Museum and the Gorgon pediment, then the Museum of Asian Art at the Palace of St. Michael and St. George. In the evening, the Liston arcades are the place for an aperitif, and a taverna in the Old Town for dinner. Daylight is short now, with about 12 hours on mid-September days, so the evening lights come on early.
Day 2 is the town’s surroundings. Go first to Mon Repos and the site of ancient Korkyra, then to Kardaki Temple on Analipsi Hill. For lunch, a taverna near the water, followed by a swim in the warm sea.
In the afternoon, visit the Achilleion for the view of the city to the north and the southern part of the island. Dinner is the time for a kumquat liqueur and spoon sweets. If rain arrives, turn the two days around: move the Archaeological Museum, the Museum of Asian Art and the Banknote Museum to the wet hours, and keep the fortress and the temple for the dry ones.
Is Corfu busy in September?
September brings Corfu a different rhythm from midsummer, set more by the shortening days and the first rain than by any rush. The sea is still warm and the terraces are still open, so the island keeps a summer feel while the light begins to fade earlier.
The rain days of the month push people into the museums and arcades, which shapes where you will find company on a gray afternoon.
Corfu faces the coast of Albania across a strait in the northeast and the mainland of Thesprotia in the southeast, so the island sits at a crossroads of sea routes. Ferries and cruise ships are part of the picture here, though the details of their seasons are for the operators to say.
What to pack for Corfu in September
Pack for a warm sea and a few wet days, with comfortable shoes for the stone lanes of the Old Town.
- A swimsuit and a quick-dry towel, because the sea is near 80 degrees.
- A light rain jacket, since rain falls on about one day in four.
- Sunscreen and a hat for the fortress ramparts and the beaches.
- Shoes with grip for the stone ramps and lanes.
- A light layer for the nights, as lows drop into the mid-60s.
- A small bag for a jar of kumquat preserves.
Good to know before you go
Plan the outdoor sights, the fortress, the temple and the Achilleion, for the dry days, and keep the museums for the wet ones. The sea stays warm, so the swimming does not have to be rushed.
Corfu in September vs August and October
Four weeks earlier, in August, Corfu is hotter and very nearly dry, with the sea a degree or two warmer and the days over an hour longer. It is the month for a beach-focused trip, with the least risk of a rained-out day. The price of that choice is the heat, which makes climbing the fortress or wandering the Old Town tiring at midday.
Four weeks later, in October, the air is cooler, the sea has dropped to about 75 degrees and rain falls on nearly one day in three. The days are down to a little over eleven hours, so sightseeing has to be fitted into a shorter window. Museums, tavernas and the wine and olive country carry the trip more than the beach does.
September sits between the two. Travelers who want a swim and a sightseeing trip in the same days will find it here, while those who want guaranteed sun should look at August, and those who want cool walking weather and a quieter table should look at October.
Is September a good time to visit Corfu?
Yes, September is a good time for travelers who want a warm sea, a walkable town and a taste of the island’s harvest, and who can take a few rainy days in stride. It suits anyone who likes to mix swimming with museums, fortress walls and long lunches.
On arrival, start with the Old Town on foot and the fortress, then plan the rest around the forecast, putting the swim on the sunny days. What is special about September in Corfu is the combination: a sea that still holds the summer, a wine country entering its harvest, and a town where the first rain of autumn sends everyone under the arcades for another coffee.
