Sunless in Seattle – Two Rainfall Records Smashed

Only eight sunny days since October 1, 2016

Between Oct. 1, 2016 and April 25, 2017, a whopping 44.69 inches of precipitation had been measured at Seattle-Tacoma International Airport. This toppled the previous October-through-April record for the city set just one year ago and is far, far above – almost 14 inches above  – the average for those seven months combined –  more than 44 percent above average.

What’s more, the Emerald City recorded 144 days of measurable precipitation during that period, smashing the previous record of 137 days set in both 2010-2011 and 1998-1999.

There has been at least .01 inch of precipitation at SeaTac Airport for 70 percent of the days since Oct. 1, far surpassing the roughly 53 percent of wet days in a typical October through April, according to National Weather Service 30-year average statistics.

Other parts of the West also experienced historic precipitation during this period.

Through Monday, SeaTac Airport has managed a total of eight “sunny days” – defined as a daily average sky cover of 30 percent or less – since Oct. 1.

This means that Seattle rainfall records have broken in four of the last 18 years.

And remember, Seattle just endured its coldest winter on record.

Hmmm. Is this just a coincidence, or are we beginning to see a pattern here?

  1. Wonder if one can get use to eating seaweed and tomatoes with no flavor? My poke plants do rather well in a sunless environment but not so well in a cooler climate. May have to doze large sloping hills here for my strawberries with roofing and shoveled drainage as they only require roughly 1″ of water per week. Oh well seaweed it shall be I suppose.

    Didn’t think anywhere on earth can actually get too much rain ..even rain forests have a dry season.This could be the fuel a worldwide ice sheet needs to get a foothold from the north and south poles.The link above says that climate can change from cold too much colder ..just the primer to allow ice sheets to survive through the summer.Never seen so much moisture up here n.east ..great Lakes spilling over break walls with minor storms..florida as dry as pepper.

  3. On Superior, Michigan, and Huron, we haven’t seen two-year water level increases of this magnitude” in recorded history, said Keith Kompoltowicz, a hydrologist with the U.S. Army Corps of Engineers district office in Detroit, in an interview with the CBC.
    This is an eye opening quote from this hydrologist in my opinion …in recorded history he says..there’s hundreds of years of water level recordings.Once again ..fuel for some climate enigma just around the corner.

  4. With just 8 sunny days solar power must be less productive?
    Though this area is subject to an atmospheric river from the Pacific bringing rain, the current solar minimum and resultant Svensmark effect will engender rain worldwide which can only further complicate the viability of the troubled alternative energy sector.

  5. The moisture going into the Northwest is not that unusual, yes record breaking, but not by that much. The moisture going into the Southwest is not that unusual, yes record breaking.

    What is totally unusual is for Washington, California, and Oregon to be receiving record breaking moisture at the same time.
