What the 2015-2024 records (Les Machines de l'île) show, season by season, to compare at a glance instead of reading twelve rows of a table.
The timing is right, so it is right for everyone: in these months the best places to stay and the small-group tours go first. Here is where to start.
Some links are affiliate links: we may earn a commission, at no extra cost to you. The selection does not depend on these links.
The time between sunrise and sunset, from shortest to longest. Not to be confused with the sunshine hours in the table above, which count clear skies. In June there are 15h54 of daylight, in December 8h30, a difference of 7h24.

What comes back every year, and when. One of these events fills the hotels and pushes prices up: something to aim for or to avoid, depending on what you want.
The Cité des Congrès runs short classical concerts back to back from morning to night for five days, around a theme.
The metal festival sets up in Clisson, south of Nantes, and fills accommodation for thirty kilometres around.
A green line painted on the ground links artworks, gardens and pop-up bars across the city, from early July to late August.
Jazz on the quays and heritage boats on the Erdre, on the last weekend of August or the first of September.
