I found this delightful anecdote that I wanted to share from The Morning Post, Monday, 05 July, 1819:
According to our free resource, the Regency Weather guide, the mean temperature was 16 C or 61 F in July of 1819, and was generally a wet year, but it seems July and August, at least according to the newspapers, showed some high and dry temperatures. An Inverness paper in September shared that the hot weather caused an inundation of “canine madness” that was troubling to many cities across the U.K. Another paper reminded people to take care and drink lots of cold water, as to avoid illness or death.
Our Regency Weather shows the winter following was severe, with extremely low temperatures in southern places like Tunbridge Wells.
Beyond the weather, I found the idea of a “white party” in the park particularly fascinating, although doubtless it was to provide some relief from the repressive sun. The glories of a neat turned ankle in a fringed satin boot!
