Unfortunately Just saw your post. We are in SE Arizona. The advice below is good. Hillsboro is a good area. Just ask, be polite, check with local chapters. There are some good spots around White signal by Silver City.
Monsoons on the AZ, NM area generally occur in late June early July through early September but times can vary.
If you make another trip send me an email, will get some data together for you. We have a good river to dredge year round, dry washing, high banking and lots of contacts, only 125 miles east of Hillsboro.
