Yeah, the August 2023 heatwave was a beast and was absolutely on the level of any non-2021 heatwave for the Portland metro.
Of course I'd wager that a 2023 level event will be more of an every 5-10 year occurrence now for us moving forward. 2021 level events will still be extremely rare, and then there's that happy space in between the two that we'll probably see every 15 or so years (e.g. PDX up at 110-111).
