The 2017 monsoon started a bit later than average but more than made up that with numerous storms throughout much of July and early August. Tucson recorded its wettest July on record and second-wettest month on record, and it and many other stations across the region have already surpassed their normal cumulative values, with some even exceeding their seasonal (June 15 – Sept. 30) average.
July was the wettest July on record in Tucson, with the airport receiving 6.80 inches of rainfall, more than triple the average.
Forecasts favor above-average precipitation for all of the Rio Grande/Bravo Basin through October.
The official start of the monsoon was June 15, but widespread activity started relatively late this year, especially in southern Arizona. There, numerous storms in mid-July brought widespread and frequent precipitation activity, boosting the percent normal monsoon precipitation in several locations. New Mexico had a comparatively earlier start to monsoon activity, which is expected given the typical spatiotemporal progression of the monsoon, and has seen more steady and widespread monsoon activity, as evidenced by the percent of days with rain.
