Welcome To Halloween! Likely a Record Cold September Day


Today was sure a dark, drizzly, & dank day (like the alliteration?). The afternoon high (as of 5pm), was only 59 degrees in Portland.  That’s what we typically see in late October!  Now at 5pm it’s 59 degrees at PDX and there’s a decent chance we jump to 60 next hour.  Update:  6pm it is 60 degrees at PDX.  If we don’t rise above 60, it’ll be a record cool high temperature for the day.


Thanks to Brian Schmit for pointing that out and the highlighted chart.  He also pointed out that IF we don’t hit 60, it’ll be the earliest such occurrence in PDX history in late August/early September!  That’s a huge change from the month after month of warm/hot weather we’ve been seeing.

My 14 year old son decided to come to work with me because I told him the cool skate park near the station on the westside would be dry.  He was skeptical all the way until we hit Sylvan.  Just like going over the Cascades and leaving the marine layer, suddenly the Tualatin Valley was under beautiful blue skies and roads were dry…I think I heard angels singing…funny how the sun can lift your mood (whether it’s warm or cold) after sitting through a day of drizzle/rain and clouds.

Notice how much warmer it was today south of the ‘ol Willamette Baseline(Stark Street on eastside and Baseline Rd westside).  Low 70s in the valley…much more comfortable.

    Hello Mark,

    I appreciate your honest and frank weather observations. You give a really good idea of what is happening in the weather and in your mind.

    Also like the rain map you provided in the subsequent post. Most of us probably intuitively know that information but it’s nice to see it confirmed on the map. The truth is, Portland presents extremely complex weather patterns and I don’t know if I’d want to be a meteorologist here. All the more reason I appreciate your blog. Thanks Again!!

  3. Dave in SW PDX (235') says:

    I recorded a high of 64.3° here on the west side of the Tualatin Mountains.

  4. David B. says:

    59 was the high here today, too.

    • David B. says:

      Now 57 and falling, so it’s safe to say this will be the first sub-60-degree high of the season for me.

    70 at 6:00 PM after a high of 73, 7 degrees below normal. Still partly but I expect the clouds to clear by midnight with lows in the middle 40,s. Peace

  6. That’s pretty chilly for Portland! We had mostly sunny skies instead(after some light morning showers) and a high of 65F.

  7. Mark, your entries with interesting information and wonderful graphs are always welcomed. Thanks.

  8. Do you know where I can get the record warm lows and record cold highs for The Dalles Municipal Airport (DLS)? I can’t seem to find them anywhere….
