Where is the closest North American climate twin to Dubai? For starters, Dubai, though averaging less than 5 inches of rain a year, is actually very muggy. Not sure why; I guess it's because the Persian Gulf's water temp averages 90 degrees in the summer? But with such warm water temps, you'd think they'd get hurricanes/tropical storms, but obviously they don't, since they're still a desert. Think Phoenix temps with Gulf Coast humidity, and you've got Dubai in the summer.

So where in North America averages well under ten inches of rain a year, is on a warm, shallow sea, and thus sees very muggy weather, with high dew points? After searching high and low, I think I've found the answer:
Puerto Penasco, Sonora, Mexico.

This Mexican resort town sits in the Sonoran Desert, on the northern tip of the Gulf of California, and is the closest beach town to Phoenix and Tuscon. At this point, the continental shelf extends far into the Gulf of California (much of the northern part of the Gulf of California is no more than 100 feet in depth). This allows for far warmer water than the main branch of the Pacific at the same latitude (82 degrees on average here during late summer).
Look at those summertime night time low temps! They remain a wonderfully warm 74-75 degrees in August (must be because of the high dew points). Right now, it is 94 degrees in Puerto Penasco and very humid, a dew point of 79. Tonight is forecasted to be a very warm 85 degrees (not much diurnal variation, must be the humidity keeping it warm).
Admittedly, it is about ten degrees cooler than Dubai during the summer, and the winters are ten degrees cooler than Dubai winters. Also, Puerto Penasco does get some tropical storms from Southern Mexico, and a noticeable summer monsoon season (though not as pronounced as it is in Phoenix).
