Monsoon 2022 continues to be active. Multiple outflows converged on the Valley of the Sun during the afternoon of June 26th, resulting in the formation of strong to severe thunderstorms. Officially, Phoenix Sky Harbor picked up 0.18" of rain, setting the record for the wettest June 26th on record. This was not a particularly hard record to break, considering this is only the 4th time rain has fallen on June 26th. The old record was 0.07" set in 1927.

Another, perhaps more interesting fact, is this is the 3rd day with measurable rain so far this month. Our of 127 years of weather records, this is only the 10th year that there have been three or more days of measurable rain in June. The record number of days is four, and with more rain in the forecast, we might just tie the record.

Monsoon 2022 officially started on June 15th and since then (through June 25th), Phoenix Sky Harbor has measured 0.14" of rain. This makes it the 10th wettest start to monsoon since records began in 1896. Average rain during this time is just 0.01".

Also of note, over the past 127 years (since 1896) measurable rain has only been recorded in 21 years during the June 15th through June 25th time period.
