A study against the weather record

Gustave Courbet

La Falaise d’Étretat après l’orage

1870 · Musée d’Orsay, Paris, MNR 561

Courbet spent August and September 1869 at Étretat and titled this canvas after a storm. Was there a storm on this coast while he was there?

1832the last time, Le Havre’s oldest inhabitants said, they had seen a storm as violent as the one of 11–12 September 1869, a month into Courbet’s stay 25 km up the coast.

How this study was read

The method in full
  1. What is written

    Begun at Étretat, where Courbet stayed in August and September 1869; signed and dated ’70 and shown at the Salon of 1870.

  2. Records of those days

    • The regional pressLa France, La Liberté, L’Abeille cauchoise and the Journal de Bolbec on the storm of 11–12 September 1869, read through Gallica.
    • Paris-ObservatoireDaily rain and temperature for the whole stay, 183 km inland, the only open daily series for 1869 in the region.
    • Maupassant’s recollectionCourbet painting at his window in the house against the Falaise d’Aval while a storm drove the sea at it, Gil Blas, 1886.

    Not found or not yet searched

    • Météo-France’s open daily data has no station anywhere in Seine-Maritime for August or September 1869.
    • The Observatoire’s printed bulletin logged Le Havre each morning, but the Météo-France library licenses its scans for private use only, so only the storm mornings are cited, not the daily table.
    • Courbet’s own letters are quoted only as Sotheby’s summarises them.
  3. Each claim tested

    • “after the rain”, Orsay on this canvas, and the storm in its title. On the night of Saturday 11 to Sunday 12 September 1869 a Channel storm struck Le Havre, Fécamp and Dieppe, the most violent at Le Havre since 1832. At 7 a.m. on the 12th the Observatoire’s bulletin logged Le Havre at 745 mm with a “tempête” and the sea “plus que furieuse”, and on the 13th reported the storm still blowing in the Channel. At Paris the afternoons cooled from 26.4° on the 9th to 18.5° on the 12th.
    • “pour voir un ouragan”: Maupassant on Courbet painting The Wave at Étretat in a storm. A storm of that force is on record on this coast during Courbet’s stay, on 11–12 September 1869; Maupassant gives no year.
    • The day and the storm of the canvas itself. The canvas is dated ’70, months after the stay; which storm, if any one, the title means is not recorded.
  4. Verdict

    Courbet’s stay at Étretat began in one of the driest Augusts on the Paris record and was broken, a month in, by the equinoctial storm of 11–12 September 1869, the worst at Le Havre in 37 years. On the coast, the Observatoire’s 7 a.m. bulletin logged a “tempête” at Le Havre on the morning of 12 September; the rest of the coastal evidence is the newspapers.

    • Partially agreesA storm while Courbet was at Étretat A great Channel storm struck this coast mid-stay; nothing ties the canvas to it.
    • Partially agreesMaupassant’s hurricane A storm of that force is on record in September 1869; his account is undated.
    • UnknownThe day painted Dated ’70, months after the stay.

What this cannot tell you. Paris-Observatoire is 183 km inland; it can show the season, not the coast. Météo-France flags the 1869 Paris values as filtered, not yet validated. The storm is known from newspapers written in its aftermath, not from instruments at Étretat.

Step 2 · Records of those days

Paris every day, and the coast in a bulletin

Météo-France’s open daily records have no station anywhere in Seine-Maritime for August or September 1869. The nearest open daily record is the Paris Observatoire, 183 km inland, which can show the season but not the sea. It shows a very dry August, then a broken September. The Observatoire also printed a daily bulletin with a 7 a.m. line for Le Havre. The Météo-France library licenses its scans for private use only, so this page cites the storm mornings from it rather than reproducing the table. For the rest of the coast’s story, the record is the newspapers.

Step 3 · The claims tested

The storm of 11–12 September 1869

A month into Courbet’s stay, on the night of Saturday 11 to Sunday 12 September, a Channel storm struck Le Havre, 25 km down the coast, and Fécamp, 14 km up it, and Dieppe beyond. Le Havre’s oldest inhabitants said they had seen nothing so violent since 1832. The wind rose at about eleven o’clock and, by one account, raged for forty-eight hours. At 7 a.m. on the Sunday the Observatoire’s own bulletin logged Le Havre with the barometer at 745 mm, a west-north-west wind at “tempête”, rain, and the sea “plus que furieuse”. The next morning the sea there was still “furieuse”, and the Observatoire reported the storm still blowing in the Channel. Inland at Bolbec, 25 km from Étretat, slates littered the streets and felled branches the fields. Seventeen years later Maupassant remembered finding Courbet at his window in the house against the Falaise d’Aval, painting while a hurricane drove the sea at it; he gives no year, but a storm of that force is on record while Courbet was there.

“un ouragan aussi violent que celui qui, la nuit dernière et ce matin, ont passé sur nos côtes, en portant partout la désolation.”

a hurricane as violent as the one that passed over our coasts last night and this morning, bringing desolation everywhere.

Le Havre’s papers, as reprinted in La France, 14 September 1869, p. 3: its oldest inhabitants had seen nothing like it since 1832

“C’est vers onze heures que le vent s’est mis à souffler avec une force terrible.”

It was at about eleven o’clock that the wind began to blow with terrible force.

The same report

“La tempête, amenée par cette bourrasque, continue dans la Manche”

The storm brought by this squall continues in the Channel

The Paris Observatoire’s summary for 13 September, printed in La France, 14 September 1869

“Tous les journaux sont pleins du triste spectacle des désastres occasionnés pendant une tempête des plus violentes, qui a sévi quarante-huit heures.”

Every newspaper is full of the sad sight of the disasters caused by a most violent storm, which raged for forty-eight hours.

Journal de Bolbec, 18 September 1869, p. 1

“A Dieppe, à Fécamp, les dégâts n’ont pas été moins terribles.”

At Dieppe and at Fécamp the damage was no less terrible.

The same

“Pendant toute une partie de la nuit de samedi à dimanche, et hier dimanche toute la journée, un vent venant de l'ouest n'a pas cessé de souffler en tempête.”

For part of the night from Saturday to Sunday, and all day yesterday, Sunday, a west wind never stopped blowing a gale.

La Liberté (Paris), 14 September 1869, p. 3, “La tempête du 12 septembre”

“vous êtes aux premières loges, ou à peu près, pour ressentir les effets et contre effets du grabuge équinoxial!”

you are in the front row, or nearly, for the effects and counter-effects of the equinoctial uproar!

A Paris correspondent to L’Abeille cauchoise (Yvetot), 15 September 1869, p. 1

“j'étais venu sur la plage, pour voir un ouragan.”

I had come down to the beach to watch a hurricane.

Guy de Maupassant, “La Vie d’un paysagiste”, Gil Blas, 28 September 1886, recalling Étretat “deux ou trois ans plus tard” than an earlier visit; no year given

“De temps en temps il allait appuyer son visage à la vitre et regardait la tempête.”

From time to time he would go and press his face to the window and watch the storm.

Maupassant, the same, on Courbet in his house against the Falaise d’Aval

“Or, cette œuvre devint « la Vague » et fit quelque bruit par le monde.”

That work became “The Wave” and made some noise in the world.

The same

Step 4 · Why the verdict stops at the season

Painted after a storm, not of one

Orsay reads the canvas as the clear, washed light after rain, the second half of a pair with The Stormy Sea. By Sotheby’s account of his letters, Courbet painted both large Salon seascapes at Étretat, but this canvas is signed and dated ’70, months after the stay. No letter or record says which storm, if any single one, the title looks back to, so the storm of September 1869 is the strongest candidate on record, not a date for the picture.

“In summer 1869, Courbet arrived in his turn in this small Norman town.”

Musée d’Orsay

“The clarity of the air and the limpid light after the rain are magnificently caught.”

Musée d’Orsay, on this painting

“The two canvases, painted about the same time, set up a dialogue as if they were describing successive phases of the same phenomenon.”

Musée d’Orsay, on this canvas and The Stormy Sea, both sent to the Salon of 1870

“Courbet painted this view looking out over the English Channel during a visit to Étretat along the coast of Normandy in August 1869.”

The Metropolitan Museum of Art, on Courbet’s The Calm Sea, 29.100.566

“By the time Courbet returned to Paris, he had painted twenty seascapes, with two of the largest views destined for the Salon of 1870”

Sotheby’s, 2020, citing Letters of Gustave Courbet, ed. Chu (1992), no. 69-9
