Bison Futé this weekend of August 22-23, 2026: how to avoid traffic jams in Île-de-France?

Bison Futé flags this weekend as a peak period for post-holiday returns. From Friday the 21st to Sunday the 23rd of August, 2026, traffic in Île-de-France is expected to be heavy, with the A6, the A10—and, from Sunday, the A13—likely to show the main congestion. School holidays are winding down, and the bulk of the flow is people returning from coastal regions to major cities, Paris leading the way.

In terms of return travel, the three-day period is rated orange nationwide. Friday and Saturday even turn red in the Southwest, the Mediterranean Arc, the North, and the Northwest. Not as severe as the Black Saturday at the start of August, but enough to substantially lengthen journeys on major routes. So we advise you to time your return carefully.

Friday, August 21: first slowdowns on the A10 and A6

In Île-de-France, the first slowdowns tied to the return flow appear this afternoon on the A10, between the Saint-Arnoult toll barrier and Wissous, then on the A6 from Corbeil to Wissous. Coupled with Friday evening commuter traffic, they clog the roads well into the evening. Bison Futé’s tip is simple: enter or pass through the region before 12:00 or after 23:00.

At the national level, when looking at responses, it's better to avoid:

• the A63 between Bayonne and Bordeaux, from 2 p.m. to 10 p.m.,
• the A10 between Bordeaux and Poitiers, from 5 p.m. to 10 p.m.,
• the A9 between Narbonne and Montpellier, from 4 p.m. to 6 p.m.,
• the A7 between Marseille and Orange (10 a.m.–5 p.m.) and between Orange and Lyon (10 a.m.–10 p.m.),
• the A75 between Béziers and Clermont-Ferrand, from 11 a.m. to 6 p.m.

Saturday, August 22: vigilance remains in effect

The same scenario on Saturday, with slowdowns starting late in the morning on the A10 (Saint-Arnoult toward Wissous), then on the A6 between Corbeil and Wissous. Traffic remains heavy well into the evening. To dodge the showers, the best option is to join or cross Île-de-France before 10 a.m.

Elsewhere in France, for those heading back, the routes to avoid are notably:

• The A11 between Nantes and Angers (10:00–13:00) and between Angers and Paris (11:00–15:00),
• The A84 between Rennes and Caen, from 11:00 to 16:00,
• The A10 between Bordeaux and Tours, from 14:00 to 19:00,
• The A7 between Marseille and Orange (09:00–13:00) and between Orange and Lyon (10:00–19:00),
• The A75 between Béziers and Clermont-Ferrand, from 10:00 to 14:00.

Sunday, August 23: the return surge peaks, and the A13 joins the fray

Sunday marks the peak of weekend departures. By late morning, traffic is heavy on the A10 and A6, and the A13 (the Norman axis) joins in from mid-afternoon. Delays can continue well into the evening. As the day before, the aim is a return before 10 a.m. to avoid the worst.

For the rest of the network, in the return direction, we avoid it if possible:

• The A10, between Orléans and Paris, from 10 a.m. to midnight,
• The A10, between Bordeaux and Poitiers, from 11 a.m. to 7 p.m.,
• The A9, between Spain and Narbonne (11 a.m.–6 p.m.) and between Montpellier and Orange (noon–7 p.m.),
• The A7, between Marseille and Orange (10 a.m.–5 p.m.) and between Orange and Lyon (10 a.m.–10 p.m.),
• The A71, linking Clermont-Ferrand and Orléans, from 3 p.m. to 7 p.m.

Note that on Monday, August 24, traffic is generally flowing smoothly nationwide. In Île-de-France, however, some slowdowns could appear in the afternoon on the A10 and A6, starting around midday.

To track real-time traffic trends, you can check the official site Bison Futé and its weekend page, as well as the Sytadin map for Île-de-France. A quick look at Météo-France vigilance before you hit the road is also a wise habit, especially during summer showers. And on the road, keep the basics in mind: regular breaks, safe following distances, and speeds adapted to conditions.
