Four letters show weather changing how Van Gogh worked and how he later understood a painting. This page reads what he says. The weather he describes is tested, claim by claim, against the rain gauges, thermometers and wind records of those days in the weather study.
Tested against the records
“The days of mistral and rain”
Saint-Rémy’s own rain gauge stayed dry from 5 to 30 September 1889, the weeks letter 806 remembers as “days of mistral and rain”. At Arles, June and July 1888 were the wettest of 17 summers on record, 1882–1898.
Van Gogh describes deliberately painting outdoors in the mistral and completing his summer-evening canvas in one sitting. Weather enters his explanation of working speed and handling.
Evidence role: the artist’s account. Letter dates do not establish the exact dates of all events described.
Van Gogh describes changing his working position because wind made the easel unstable. This is evidence of how he says he worked, not a measurement of wind speed.
Evidence role: the artist’s account. Letter dates do not establish the exact dates of all events described.
Van Gogh writes that once “the days of mistral and rain came” he preferred the version of the Reaper painted from life. He describes cold weather bringing back the heat of the wheat field: weather shapes his later reading of the painting as well as its making.
Evidence role: the artist’s account. Letter dates do not establish the exact dates of all events described.
Writing about work on a ravine, Van Gogh describes securing an easel among stones against wind. The letter supplies a physical working constraint; its date is approximate and is not an exact execution date.

Selection: four passages chosen for concrete connections between weather and artistic practice. Brief quotations are retained; full letters and images remain with the scholarly edition. They raise a different question from the Constable records.
