80 Degree Record Tied

We hit 81 in Portland today, which ties the old record for most 80 degree days in one season.  During the blazing hot summer of 1967 we had 84 days at/above 80 degrees.  As of today we’ve seen 84.


One difference this year compared to 1967 is that the heat arrived much earlier.  That year it was July/August, this year it was mainly June/July.  August was warmer than normal but not a crazy hot month.  September will end up slightly below average.

Note we’ve seen DOUBLE the number of 80 degree days as in the cool summers of 2010-2011.

Tomorrow we should hit 80 again but that might be it for the season.  The pattern still looks ridgy the first part of October, but that doesn’t mean we’ll hit 80 again.

    Anyone seen an aircraft carrier around here?

    82 at 4:30 PM. Great night for a walk in the park. Really looking forward to O.M.S.I conference on October 24th. Always fun to hear other points of view. If it gets any more popular the organizers will have to find a larger location. Peace.

  3. Based on the long-range outlook we could have several more 80s in the 1st half of October at PDX. All you need is a sufficiently warm airmass (check), and a little bit of offshore flow (maybe?). Who knows…maybe we hit 90 days in the 80s this year – which would clearly be getting into “Mediterranean Climate Territory.”

    Role call on the OMSI get together. Who is going. I will be there 🙂

    I compared PDX and SLE for days over 80 from 2008-2015. The avg. for PDX is 61.4 and for SLE it’s 75.8. Why the difference. Quite often PDX will have morning stratus along the Columbia river where the reading in Portland are taken. Many times Salem escapes the morning stratus. Thus while Portland is 78 or 79 Salem is 81 or 82. Not a huge difference but enough to account for the variation I think. Here is the difference year by year. 2008. -1, 2009, +14, 2010, +20, 2011, +14, 2012, +20, 2013, +19, 2014, +17, 2015. +12. A much smaller difference this year because of a dearth of low clouds at PDX this Summer. And oh by the way. I imagine Hillsboro and Aurora are closer to obs from Salem’s readings. Hey Mark what’s with this oldtimer stuff I was 13 in the Summer of love and yes it was hot. One big difference was the overnight temps. This year we had 6 nights dropping to less than 50 degrees from June 1st to August 31st, all of the in the first part of June. In 1967 that happened 47 times. And we had 33 nights above 60 in 2015. Only once in 1967. The daytime temps were similar though. They also had a lot of very bad forest fires in 1967 and 500,000 acres of grass seed fields were burned in the valley by farmers that Summer. Very poor air quality, a lot of heat, and some really groovy music is what I remember from 1967. Now 75 headed for 84 at 1:30 PM. Peace.

      Overnight lows are higher due to the urban heat island effect one would think. Alot more people live here now and alot more concrete and asphalt have been put down. Good conductors of heat. There’s my theory in a nutshell.

    • I don’t have a lot of memories of the summer of ’67(not surprising considering my age then), but one thing I can recall is that we had a lot of foggy (or smoggy) days in that era, especially in the fall. A lot of residences back then here were allowed to burn their trash outdoors and there was a lot looser regulations. Can’t imagine what it would have been like this past summer if we’d still allow that burning of garbage and sawdust!

  6. Josh "the snowman" Gladstone says:

    I’m at work and have no idea what the temp is but it must be another 80 today. Looks like the split flow is starting early this El Niño winter. Ugh!! Oh well, there is always next year.

  7. I just made a list of 80F (or higher) days in my area for the past 41 years (1975-2015) for May to September. A couple of things jump out; First, we had more of those days in 2010(20) compared to 2011(17), but more importantly, the last 2 years saw a real spike upwards; 42 in 2014 and 48 in 2015. That’s not much compared to Portland, of course, but it’s quite a lot higher than my long term average of 20. Sure hope summer 2016 isn’t a continuation of the trend!

    So, the forecast for Boston/Cape Cod sure changed in a hurry. I’ve been watching it closely the last couple of weeks (thanks for the links, Dan) and it had been trending toward a nice weekend. Now, all of a sudden…


    Wouldn’t that just figure!? No worries though, I told my buddy this storm will veer to the NE back out to sea the moment my plane lands, because dome. 😀 He said that’ll be a nice wedding present.

      S. Ore. peak gets new, official name

      ASHLAND, Ore. (AP) — A Southern Oregon peak that was known commonly, though not officially, as Squaw Peak has a new name that no longer uses the word many American Indians say is derogatory.

      The United States Board on Geographic Names has approved the naming of Taowhywee Point for the 3,727-foot peak just outside of Ashland on the 1,800-acre Circle of Teran Ranch, owned by Scott Young and Sulara James.

      The couple applied for an official name in March 2007 after an American Indian friend, Robert Greygrass, told them that many consider the term squaw derogatory.

      Greygrass said local American Indians proposed naming it for Margaret Harner, a well-known medicine woman in the area during the 19th century. Harner’s spirit name is Taowhywee, a name she shares with her great-granddaughter, Agnes Baker Pilgrim, also known as Grandma Aggie.

      “I feel very honored to get another derogatory name off of the map,” Pilgrim said. “I’m very happy that we got that done.”

      At one point there were 172 Oregon landmarks that were officially named with the term “squaw,” according to Champ Vaughan, the Oregon Geographic Names Board president.

      Since 1998, the board has whittled the list to about 120, Vaughn said, but the board is limited by the requirement that all name change requests must come from the public.

      The board receives about 20 requests per year, half of which are to eliminate a name using the word “squaw,” Vaughn said.

      “People ask us, ‘Why don’t you just take the names off the map?’ ” he said. “We can’t erase names on maps. It has to stay there until we have a replacement name.”

      The ranch James and her husband own is a spiritual retreat center on land sacred to American Indians, who lived there until about 1900. They follow shamanism, the belief that there is a spirit in every living thing, which has its roots in indigenous religions, James said.

      Ted, I believe you’re referencing a different site. The Taowhywee Point you’ve mentioned here is almost 2,200 feet lower in elevation.

    • Boring Oregon says:

      Ted I really hope you are joking. That’s pretty sad if you can get offended that easily. Just sayin man.

    • Garron (1/3 of a mile from the Hillsboro airport) says:

      According to Wunderground.com, Hillsboro has had 16.38″, Portland Airport 16.14″…I guess KPDX is in a bit of a rain shadow due to the West hills…lol!

  12. Colin Bondi says:

    It looks like the trend is on the increase from 2010 to 2015 from the graph. Is there any reason to believe next year could be even hotter than this season?
