Warmest August In Portland & Salem History

You just survived the warmest August on record in Portland & Salem!  The average temperature was 73.096 degrees in Portland…got that?  That’s also the 3rd warmest month in Portland’s history.  After July 1985 and July 2009.


In Salem, the 72.47 degree temp was the 2nd warmest month in Salem’s history, right after July 2014!  So that means Salem just had its warmest two months on record.

It was the 2nd warmest August & month in Eugene’s history, only topped by the hot August of 1967.

As I mentioned in a previous post, the weirdest thing is that most people in the metro area probably wouldn’t say “…Whew!  that was the hottest summer I’ve ever been through here!”.   Joe Raineri & I were just talking about why.  The proof is that through this entire “2nd warmest summer on record” we didn’t have any HEATWAVE 2014 coverage in our newscasts.  Well it is true that leading up to the 99 degrees on July 1st the newsies got excited; we had to cancel that heatwave real quick when models cooled off.  But in the following two months I don’t think we ever made use of the phrase HEAT WAVE.   Basically we were consistently very warm through the last two months with almost no strong marine pushes to cool our highs into the 70s.

Coming up, it sure looks like September.  By that I mean it still looks quite dry the next 7-10 days and we have a mix of cool days and very warm (or hot) days.  East winds show up Thursday-Saturday which means very dry air…low humidity!  Ahh, warm (shorter) days and reasonably cool nights.   For some, now through mid-October is the best time of the year before the real rainy season hits in about 6-8 weeks.  I know some like the crisp/clear days of October, and so do I.  But those are often few and far between.  Cloudy days are far more common then.

I pushed the high temperatures up to right around 90 degrees both Friday and Saturday with decent offshore flow and sunshine.  ECMWF is more reliable I think with the slower arrival of a cool upper-level trough early next week so I kept temps quite warm through this coming weekend.  We get that cool trough early next week and then it’s likely ridging will nudge up against the coastline again.  You can see the Yo-Yo up/down weather the next 10 days on the ECMWF ensemble chart:  tseries_850t_000-360_Portland

This coming weekend happens to be at the high point on that chart…it’s going to be much warmer than the Labor Day Weekend was!

    Should break the 90+ temp record here in Eugene by the end of the weekend. Should be a toasty Duck game on Saturday with drunk tailgaters.

    As for fall/winter, a bit early to speculate…but will anyway. For all the snow that south valley residents got last winter, the low elevation ski resorts certainly did not fare so well (especially Hoodoo, Willamette Pass, Mt. Ashland, Ski Bowl). Am concerned about the financial health for these operations as none of the long range seem to be suggesting cold, wet/snowy winter for the Cascades.

    Am guessing that Nov-early Dec may be the best period for snow in Cascades relative to normal, the mid to late part of ski season more likely to stink (the infamous Government Camp “Dog-Stink” from accumulated dog feces from all the dogs running around without fresh snow to poop on).

      Those long range models are banking on the development of an El Niño, which so far is failing to materialize, though the last week saw a 0.2C rise in SSTs in the ENSO 3.4 region, which is still below the +0.5C needed to begin running the clock toward an official El Niño.

      Who knows what will happen? I guess we’ll have to wait and see.

    Ahhh signs of winter
    Winter weather advisory for snow at Glacier Park in Montana
    Blizzard Warning for southern Brooks Range in Alaska
    Excitement starting to begin!

    Just letting everyone know I just moved back into the area so I will be posting more often. Had some stark street pizza today :). When are we having a get together? Just saw you on tv, mark. Been working out? You know it is slow weather when you have to mention a rogue shower between Gresham and Corbett. Lol

    Enjoying the very comfortable weather today! GO AWAY 90’s!

    Rain? Well, more like the rain you see at the coast. Hills have disappeared and drizzle has set in. Where’d this come from? Lol

  6. High Desert Mat says:

    Mark, your second paragraph doesn’t make sense to me. You say, ” in Salem, the average of 72.47 is Portland’s second warmest month in history. Right after July 2014!!” Lol. Currently 77 in Redmond with nothing but sunshine.

  7. WEATHERDAN says:

    71 at 11:00 AM after a morning low of 59. Looking at about 81 today and 77 on Wednesday. Then a big warmup to about 95 on Friday and Saturday. Saw the Beach Boys at the State Fair yesterday and the weather was perfect. 83 and sunny. Looking like another dry warm month ahead. If the NWS is right we are in for a dry and warm Autumn as well. El Nino looked like a sure thing this Summer but now it might not happen. That could mean a big change in the Winter outlook. I guess we’ll just have to see what happens. Peace.

    • Steve says:

      I’m not so sure it really matters the state of El Nino, La Nina, or Neutral; each of which seem capable of producing every type of winter. So as far as winter goes, it seems each of these conditions are media hypes!

    Next weekend should be nice. 🙂

    Last weekend (Labor Day w/e) was kind of a mess. Disappeared up into the High Cascades near Olallie Butte/Lake — went to bed under a full starry sky Friday night, woke up Saturday morning to cold rainfall that lasted 8-9 hours without a break. Rain finally stopped and the clouds started to pull apart for a short bit late afternoon, but drizzle returned and then solid moderate rain with wind that lasted through the night. All in all, I would estimate we had about 3/4 inch of rain Saturday and another 1/2 inch Saturday night, judging by the amount of standing water we had to dump out of our camping supply bins. Wish I’d’a taken a rain gauge with me!

    1.25″ at the Cascade Crest from 5am Saturday to 5am Sunday seems a reasonable estimate, and lows in the upper 30s both nights made for a cold, wet, almost miserable time. We watched at least half, if not 2/3 of the other campers in the area bail, so we spent the afternoon Saturday driving around collecting up all their abandoned firewood. It was a struggle keeping our fire lit and the kids dry and warm, but we stuck it out and were rewarded to two beautiful dry days on the lake with very few other people around.

    Definitely worth it!

    If you just took the average high temps for the two months not including overnight lows, would we still be ranking that high without any heat waves? I know the warm nights really bumped up the overall average.

    It’ been great for my tomatoes! Any thoughts on late fall and winter weather yet? Saw the Farmers Almanac note on Facebook-how about your thoughts Mark??

  11. None of the major networks are calling for anything other than warm/dry as we move through September. So I’m aiming my bets pretty high this month on the “contest.”

    Second warmest month in Salem’s history…. 🙂 I’m quite happy with this summer! The second round of raspberries is starting and the tomatoes that were planted late are actually going to ripen!
