September puts four coasts at their peak, and three of them run down the same Atlantic front. Portugal gets there through a combination that does not repeat: the nortada dies, the autumn swells return and the water is at its 18° ceiling. France gets there because the first autumn lows land on sandbanks August has just rebuilt. Ireland gets there on 15° water, the warmest it sees all year, with the swell coming back on top of it. Senegal is three thousand kilometres further south, at 29°. Ten other countries are in good season, northern Spain among them with its window just reopened, which makes September the most generous month of the year.
Sorted by the coasts at their peak in September, then by verdict.

Verdicts are read from published surf guides and signed by us. Temperatures are monthly means published for one named break per country, not an average of a coastline. Swell height is left out on purpose: no source publishes it month by month for all of these coasts, and a figure measured one way here and modelled another way there would not compare.
