PORTLAND, Ore. (KOIN) –  Summer heat will impose on a few of our spring May afternoons starting today and if you think this is a bit too warm, you’re right.

Just to preface, our average high temperature around this time of the season is around the mid to upper 60s in Portland. The forecast this week has been way above average, and there is no surprise, we are flirting with record high temperatures.

Believe it or not, if we break a record high temperature this week, it won’t be the first of 2019. On March 20, 2019, Portland broke a record with a high of 72 degrees. 

With seasonable temperatures somewhere far away, we are looking at a scorching week (relatively speaking) for this second week of May. Temperatures are set to potentially hit near 90 degrees or above Thursday through Saturday.

So you may be asking yourself, well is this record-breaking heat? It likely will be, so the answer is probably yes. 

Does it feel like this has been the norm around here lately? Well, “records are meant to be broken,” but, we’ve had quite a few over the past 9 years (59 and counting) when it comes to recording high temperatures at the Portland airport weather station.

We may make some history here this week with some new record high temperatures for the month of May. Keep in mind, most of the data goes back to 1941 and some data even from 1874 for some sites downtown. 

Here in these graphics, you can see how many record high temperatures we’ve broken since 2010 by month, and then which months have seen the most records.
 

These are the number of record high temperature set at the Portland Airport by year, dating back to 2010 and counting. These do include every month and doesn't tell the full story of record heat by month.

There does happen to be a bit of slumber when it comes to the month of May. What I mean by that, is there have only been two high record temperatures since 2010 in the month of May.

That may seem about right, and it’s possible that is the way it should be, I do not have a probability of how often record high temperatures are broken from year to year. However, the month of August has seen 8 record high temperatures since 2015. 

These are the number of record high temperatures broken by month since 2010.
