Southwestern US Monsoon 2025

[Warren Faidley]

It's that time of year to start the annual monsoon thread.

Still too early to make a reliable forecast, but current trends suggest the usual start in about three weeks.

Some early wild cards this year include tropical activity near the Baja Peninsula that could cause early RH surges and the effect of recent rains
on stabilizing dust beds. I have not had time yet to inspect the dust beds, but it only takes a few weeks of 110º F+ to bake them properly
for haboob production. In fact, sometimes, early rains can produce small plant blooms that dies in the heat, becoming potential airborne particles
during dust storms.

I will be going live this year on YouTube during the BIG monsoon / haboob days, so stay tuned.

I wish the desert wasn't a 20 hour drive for me. I have yet to see a Monsoon season in Arizona but it is on my bucket list.

Well, we do have a monsoon season in Colorado, and it is often good for lightning. Haboobs, not so much, though they can occasionally happen.

I'm looking forward to 'monsoon season' as I always do, not only because I like rain, but also (and more importantly) because I love lightning!

I'm just hoping that this years season isn't delayed so late like last year's was...I was pretty much given up last year considering it a dud by the time it finally fired up.

I'm sire the Arizona monsoon would be cool to see season (and I'd like to), but its just too far away.

I've always wondered what the Arizona monsoon looks/feels like to a visitor. Living in southern AZ and enduring months with zero precipitation, very little humidity and a thermometer that inexorably creeps up and up, when monsoon storms arrive it doesn't feel like something that should be possible. The sense of awe is very intense. Not sure if that could register to someone who pops in from elsewhere in July or August, although they're still beautiful storms and the opportunities for really unique photography are abundant.
