Like September, October was a dry month. Total rainfall for October was .70 inches, more than twice the rainfall of September (.31 inches), but still significantly less than what the Vineyard usually gets. Normal average rainfall for October is 3.39 inches. The jet stream, which moves storms across the continental United States, has been moving rainfall through New England, but the storms have been passing north of the Vineyard.
According to the National Weather Service cooperative weather station in Edgartown, there were 11 days in October which produced measurable precipitation. Most of these showers were in 1/100ths of an inch and less than a 10th of an inch.
Three rainfall events were noteworthy: On Oct. 5 .11 inches of rain fell; on Oct. 8 .26 inches fell, while Oct. 24 saw .27 inches of rain.
