August 13, 1789
The week past has been the hottest weather experienced here since the settlement of Shelburne. On Tuesday and yesterday the thermometer, hanging in an open passage, in the shade, was up to 85 at three o'clock in the afternoon.
Today the thermometer, hanging in an open passage, in the shade, hovered around 68 at three o'clock in the afternoon. That's about 19 degrees in Canadian.
The Town of Shelburne is hotter than McNutt's Island in the summer. The island's summer is foggier and cooler, moderated by the Atlantic. Shelburne is deep inside the inner harbour; the island is on the outer edge of the outer harbour. I would bet that if The Pennsylvania Mercury's correspondent had been reporting from McNutt's instead of from Shelburne he (or she) would have given a high temperature of somewhere in the seventies that day.
But this summer has been cool and wet both on the island and in town. And there's word in town that Environment Canada is forecasting a string of summers like this one for the region, an effect of the continued melting of polar ice. I haven't been able to find this in writing anywhere; maybe it's an urban legend. It makes sense, though, that huge expanses of ice melting into the northern seas would keep everything cool and foggy for a while.
Those Loyalist settlers of Shelburne were probably delighted with a temperature of 85, and went around town 220 years ago fanning themselves, shirtsleeves rolled up, grinning at their good fortune: a hot spell in August and the hottest day since they'd set foot on this stony land.
