A study against the weather record
Claude Monet
The Seine at Giverny
The Met says bad weather kept Monet’s dawn pictures of the Seine unfinished until 1897, the year of this canvas. What did the rain gauges near Giverny record in those two summers?
“Inclement weather” partially agreesDawn mist unknown
The Nephos method
How this study was read
The method in fullWhat is written
One of four canvases of the Île aux Orties, all dated 1897, painted from Monet’s boat at the mouth of the Epte during the two summers of dawn work that also produced the Mornings on the Seine.
Begun in 1896, Monet’s Mornings on the Seine series was not completed until 1897 because of inclement weather.
The Metropolitan Museum of Art, Morning on the Seine near Giverny, 56.135.4pointe d'aube, en août, trois heures et demie. … s'engage dans les prairies toutes embuées de brumes, arrive à la rivière.
Maurice Guillemot, “Claude Monet”, La Revue illustrée, 15 March 1898
Records of those days
- Jeufosse and Bonnières rain gaugesDaily rain 4.2 and 5.7 km from the island, across the Seine; Jeufosse measured every day of June to September 1897 but kept no September 1896.
- Pacy-sur-Eure and ÉvreuxDaily highest and lowest temperature 12 km away, and rain at both, for ranking the two summers against 37 to 40 years of record.
- Paris-MontsourisDaily rain and temperature from 1873 to 2024, the long series that ranks each month against 152 years.
- L’Impartial, Les AndelysThe twice-weekly paper of the district that includes Giverny, read for August 1897 and September 1896.

Each claim tested
- “not completed until 1897 because of inclement weather”, the Met on the Mornings series. September 1896 was the wettest September in 152 years at Paris (148.9 mm, against a modern 44.7) and in 37 at Évreux, and August 1896 had the third-coldest nights of 150 at Paris. The gauges nearest Giverny kept no September 1896.
- “Un violent orage suivi de grêle et de pluie … samedi”, L’Impartial on Port-Mort, Saturday 7 August 1897. Jeufosse, 4.2 km from the island, read 49.0 mm on the morning of 8 August, its second-wettest day in 1,145; Bonnières read 36.0 mm.
- “prairies toutes embuées de brumes”, Guillemot on an August dawn with Monet. Mist was not measured. The ground was wet: August 1897 was the wettest of 11 at Bonnières and the second-wettest of 38 at Évreux.
- The day and the weather of the canvas itself. It is dated only to the year, and the museum publishes no reading of its sky.
Verdict
Both summers Monet spent painting on the river at dawn were wet near Giverny. The first ended in the wettest September in 152 years of Paris records; the second brought the wettest August in 11 years at the gauge across the river. The mist Guillemot walked through was never measured.
- Partially agrees“Inclement weather” in 1896 A cold August and a record wet September; the records cannot show which mornings Monet lost.
- Partially agreesThe Port-Mort storm of 7 August 1897 The rain is in the gauge the next morning; hail and lightning were not recorded.
- UnknownMist at dawn No record of fog exists near Giverny.
- UnknownThe day painted The canvas is dated only to 1897.
What this cannot tell you. Guillemot gives no year for his August morning; published in March 1898 and writing “depuis l'été dernier”, it is most likely August 1897. Paris-Montsouris is 66 km away and Évreux 27 km; the nearest gauges are too short to rank. The Met ties the inclement weather to the Mornings, the series this canvas grew out of, not to the Île aux Orties pictures themselves.
Step 2 · Records of those days
A rain gauge across the river
In 1897 there was a rain gauge at Jeufosse, 4.2 km from the Île aux Orties across the Seine, and another at Bonnières, 5.7 km. The nearest thermometer was at Pacy-sur-Eure, 12 km south-west. Every day from June to September 1897 was measured. Rain is dated by the morning the gauge was read, so an afternoon storm appears on the next day. The summer’s wettest day came in August, the month in which Maurice Guillemot describes Monet at work on the river before dawn.

- mm at Jeufosse in August 1897, on 10 days with rain

Step 3 · The claims tested
Two wet summers
The Met says Monet’s dawn pictures of the Seine took two summers because of the weather. The first summer ended badly. At Paris, August 1896 had the third-coldest nights in 150 years, and September 1896 was the wettest September in 152: 148.9 mm, against 44.7 mm in a modern September. Closer to Giverny it was the wettest September in 37 years at Évreux and the second-wettest in 37 at Pacy-sur-Eure. The gauges beside the river kept no September that year. The second summer was wet in its turn: the storm the Andelys paper reported from Port-Mort on Saturday 7 August is in the Jeufosse gauge the next morning, and at Bonnières no August in 11 years had more rain.
- 1st
- wettest September of 152 at Paris-Montsouris: 1896, 148.9 mm on 17 days
- 1st
- wettest September of 37 at Évreux, 27 km from Giverny
- 2nd
- wettest September of 37 at Pacy-sur-Eure, 12 km
- 3rd
- coldest August nights of 150 at Paris: 1896, 11.7° against a modern 16.0°
“Begun in 1896, Monet’s Mornings on the Seine series was not completed until 1897 because of inclement weather.”

Step 4 · Why the verdict stops at the season
The mist was never measured
Guillemot describes Monet leaving the house at half past three on an August morning, crossing meadows in mist to the boat, and fourteen canvases under way at once. No station near Giverny recorded fog, cloud or wind, and the Columbia Museum of Art publishes no description of this canvas’s sky. What Nephos sees in it: a pale pink and lilac sky, the island’s trees in blue and violet, water still enough to hold their reflection, and the far bank at the left dissolving into white. The Met writes of a misty, luminous atmosphere in its own version of the same view; that is a sister canvas, not this one. The picture is dated only to 1897, so no single morning can be set against it.
“pointe d'aube, en août, trois heures et demie.”
Daybreak, in August, half past three.
Maurice Guillemot, “Claude Monet”, La Revue illustrée, 15 March 1898
“s'engage dans les prairies toutes embuées de brumes, arrive à la rivière.”
He sets off across meadows all clouded with mist, and reaches the river.
Maurice Guillemot, “Claude Monet”, La Revue illustrée, 15 March 1898
“C'est à l'endroit où l'Epte se jette dans la Seine, parmi de petites îles ombrées de grands arbres”
It is where the Epte runs into the Seine, among little islands shaded by tall trees.
Maurice Guillemot, “Claude Monet”, La Revue illustrée, 15 March 1898
“Il y a quatorze tableaux commencés en même temps, quasi une gamme d'études, traduisant un même et unique motif dont l'heure, le soleil, les nuages modifient l'effet.”
Fourteen pictures are under way at once, almost a scale of studies, rendering one and the same motif whose effect is changed by the hour, the sun and the clouds.
Maurice Guillemot, “Claude Monet”, La Revue illustrée, 15 March 1898
“The setting and the misty, luminous atmosphere are similar to that of Morning on the Seine near Giverny”
The Met, on its own version, 60.154
