Seattle approaches record streak of rain-free days
As of Thursday, Seattle will have seen 13 straight days without rain, approaching a record streak for what’s typically a rainy November period.
The last day in rained in the Seattle area was Oct. 25. As we’ve moved into November — the second rainiest month out of the year on average — we haven’t seen a single drop. The average rainfall between Nov. 1 and Nov. 6 is just under 1.20 inches, and 5.67 inches for the whole month.
According to the National Weather Service, it’s been 43 years since there’s been no measurable rainfall in the first week of November in Seattle. In total, there have been just three years where that’s happened: 1976, 1957, and 1952.
Initial forecasts called for November’s first rain sometime around the weekend, continuing at a near-constant rate for the foreseeable future. That’s since shifted, though, with dry weather potentially extending into next week.
“Our dry spell is not over yet,” said University of Washington climate scientist Cliff Mass.
Mass points out that the most up to date forecasts call for clear skies at least through the morning of Saturday, Nov. 9. That would be 14 straight days without rain, tying the record for most consecutive rain-less days extending into November.
And that could be just the beginning.
“We have a real chance, but not a certainty, of completely busting the record,” said Mass.
He references a forecasting model predicting no rainfall through Nov. 14. That would put Seattle’s streak at a whopping 20 days, marking the second longest streak in history during Seattle’s rainy season between October and February.
