Portland Oregon is pretty much a hot-summer Mediterranean climate at this point. Here's some stats from recent summers at PDX. | Month | Average High/Low (F) | Monthly mean (F) | Hottest temp recorded that month | Precipitation (Inches)
Just proof that summers are dry as fuck | | 7/2020 | 81.5/58.9 | 70.2 | 100 | 0.05 | | 8/2020 | 83.1/59.2 | 71.1 | 99 | 0.38 | | 7/2021 | 85.5/60.6 | 73.0 | 98 | Trace | | 8/2021 | 84.0/61.0 | 72.5 | 103 | 0.05 | | 7/2022 | 85.7/61.8 | 73.7 | 102 | 0.17 | | 8/2022 | 87.3/62.8 | 75.1 | 100 | Trace | | 7/2023 | 85.9/60.9 | 73.4 | 98 | Trace | | 8/2023 | 87.1/63.6 | 75.4 | 108 | 0.62 (this month actually had above average precipitation) |
As you can see, most recent summer months have mean temps that are above 71F, which to my knowledge is the threshold for a hot summer Mediterranean climate. I can't wait until they update the climate normals for P-town! |

If the official averages were over the past four years, it would be Csa, however, we use 30-year averages, not 4-year averages for a reason. I'd prefer that instead of 30 years we use the averages from when data began to be collected until now, tbh.

They will be updated in 2031 for 2001-2030 period. |

The new averages will be 2001-2030. So they update every 10 years. |

This thread is just stating the obvious - that summers in Portland are glorious.  |

I liked how you skipped July 2023. Yeah the recent summers have mostly been hot but that’s 4 years. I guess we’ll see if summers stay this hot for the next 26.

Our planet is warming and that includes Portland, so I have no reason to think that Portland's summers will somehow get cooler. Also, I did not skip July 2023. |

Almost on par with the Greek Junter. Hopefully his 8C increase in global temps over the next century that the University of Washington told him will happen, will actually happen. Otherwise no Koppen pushing for Portland. |

In his defense, he did include July 2023 in the OP: Portland Oregon is pretty much a hot-summer Mediterranean climate at this point. Here's some stats from recent summers at PDX. | 7/2023 | 85.9/60.9 | 73.4 | 98 | Trace | | 8/2023 | 87.1/63.6 | 75.4 | 108 | 0.62 (this month actually had above average precipitation) |

2014-2023 averages from NOWData for Portland Airport. 10 years is still too short but it's enough to remove a single hot month. Average temps are above the 22C threshold for both months.
First three are daily Max/Mean/Min. Next two are monthly max/min
July: 83.9/71.9/60.0 || 97.7/54.4
August: 84.9/72.9/60.9 || 100.6/53.0
In Celsius:
July: 28.8/22.2/15.6 || 36.5/12.4
August: 29.4/22.7/16.1 || 38.1/11.7
The annual max for those 10 years averaged out to be 103.1F/39.5C
For my own comparison, Milwaukee average for July 2014-2023 is 73.3 and August is 72.6. Similar temps but Portland gets higher max temps due to the lower humidity. July is 81.5/65.0 and the annual max is only 95.1
