During a heat wave in other parts of the country, Miami is frequently cooler than places with heat waves. Their problem is not high temperatures, necessarily----but high humidity.
Miami itself has only hit 100 degrees once in its history. New York City has hit 100 degrees quite a few times; and it's all-time high is 106 degrees.
It is harder to achieve extremely high temperatures in a humid airmass. That is one reason most of the world's records have been set in deserts.
The 100+ degree readings in NYC usually occur with moderate or low humidity. Traditionally 100+ degree readings in NYC occur only occasionally. It was thought global warming would make 100+ degree readings in New York routine. That has not happened in almost 10 years, what has happened is a lot of upper 80s to mid-90s readings with extreme humidity. Dew Point is a measurement of humidity. If the dew point is 70 degrees the relative humidity will be 100 percent. Growing up a dewpoint of 70 was considered very humid uncomfortably steamy. The last few summers 70+ dewpoints are routine and 75+ dewpoints once a rarity has been happening fairly often. Instead of the extremely high readings predicted we are getting Miami-like summers.
Dew points in the region are around 70 or 71 at the moment.
Back to the Pacific Northwest, they are in a world of hurt, shattering many temperatures records, not just for the day but for the month of June and even for all time.
