As weather

I visited my friends in Phoenix twice from Portland Oregon . Would not live in dusty hot city! Then they moved to Tucson. Visited twice, was warned...hot hot summer, stay inside. Love the heat. Love monsoon. Go out early morn and late evening. I live in Green Valley. I love it.

Weather summer

I have lived in Arizona since 1974...I can teĺl you this "summer" thus far, is mild...but much like the late 70's and 90's thru 2010..I guess what I am saying is, what goes 'round comes 'round. Wouldn't change the Sonoran desert for anything!

Weather Summer

AMEN!

Heat

Seattle:
Climate change.
I am looking at Seattle and New Zealand.
We had a fire when you were here, so happy the fire trucks were running.
We barely had any snow this winter and rain, what’s that?
Been here over 20 years and it’s getting worse each year.

Rain Dance.

Temps and Rain Vary from Year to Year

I have lived in Phoenix over 20 years and I am from the Midwest, so I thoroughly understand and appreciate the difference between the climates. I have noticed that most people who live in Phoenix regardless of where they are from think it is always getting hotter every year, which is not 100 percent correct. This June 2018 for the first time in several years has not yet hit over 120 as it has done past years. This year is different. I am thankful the temps have mostly stayed under 110. We actually even had a couple days in the upper 90s this June, which I don't recall happening in recent years. What I have noticed each month so far this year, there has been a week early or mid month where the temps spike up hotter than usual, then came back down about 10 or 20 degrees less. Alot of temp fluctuating every month. February had the most rain and some in early March but not since then. Often the Monsoon rains begin around beginning of July. I think the past couple years we had more rain between July through early September than in the Spring. Spring temps were later for the Midwest with snow through April, but here in Phoenix the temps ranged between low to mid 70s up to mid to high 80s through April and then jumped up to 90s and low 100s in May, which is common for that month. February had colder evening temps than usual due to the rain & December through January was warmer than usual, in the low to mid 70s mostly, which for most people is lovely weather! Yes it is hot and dry here in the summer because we live in a real desert climate, and there are many days over 100, but if you have a pool, it does help to feel cooler when outside. I prefer temps to go no higher than 105, because 110 plus is way too hot. Summer here is like winter elsewhere, in regards to staying inside more. In the summers, I mostly go out of my house in the evenings when it is not as hot. For many people, any temp over 90 or 100 is too hot, but it is rather amusing that after we have endured 100 plus heat for many months, we are very relieved and happy when it "cools" down to under 100!

I recently moved here from the Seattle area, and wow! It's so dry and hot out here so early in the year. Breaking records with heat and dryness seem to be the current problem, and seeing the signs on the freeway saying high danger from fires don't help. I've been visiting down here for the last three years and thought it might be a nice place to try up until now! I keep hearing fire trucks going by ....

hmm

Well then go back to Seattle :)

Arizona summer

You got a couple of nasty comments. Not all Arizona residents are nasty. It is very hot and dry here. It's common to leave your air-conditioned home, get in your air-conditioned car, go to the air-conditioned mall or grocery store and back to the car then home. Very early mornings have been nice so far but I know it won't last. Summer lasts about 6 months in Arizona.

2018 Arizona Monsoon

According to the almanac the precipitation forecast for Arizona (Southern part of the state) for our annual monsoon season, is to be below average. Yet we are reading in the news that they say there is a good chance for above average rainfall for us. What's it going to be?? No one really knows, do they? Except God. I will keep my trust in Him for our weather.

Rain

Dear Lord please let the rainfall be above-average or at least normal
