Back in 2003 I visited the White Mountains from Florida. I remember walking up this one hillside above the San Fransisco River. I had to stop repeatedly to catch my breath and it felt like it took me for ever, even though it was probably only 200 feet of vertical, or so. I was back in the area 2 years ago. I flew up that hillside and never even thought about it. Then I remembered 2003 and I thought of how nice it was that I lived up high.
I think Monsoon season will begin around June 20, plus or minus 5 days, not by the calendar according to the NWS, but when dew points rise dramatically, and it begins to rain over the Sacramento Mountains. It will start about 10 days later in Arizona.
