Seattle Closes Out July as Driest Since 1960

It's tough to actually receive zero percent of normal rainfall during a given month, but with only a trace of rain falling at Seattle's Sea-Tac Airport this past July, that is exactly what happened.

While technically a trace of rain is "some" precipitation, its official definition is "rainfall measuring less than 0.01 of an inch." That means if only three drops of rain fall from the sky, there was still a trace of rainfall.

The average amount of rain for the entire month of July in Seattle is 0.70 of an inch. The trace amount that fell during July 2013 was the least amount of rainfall during any July since 1960.

August will start off with a few widely separated showers around the Seattle area through Friday, but most places will not see any rainfall.

If no measurable rainfall is observed through Friday, a strong ridge of high pressure building overhead will all but ensure the streak of dry weather will persist well into August.
