Record-Setting September Heat in San Pancho on the Riviera Nayarit.

September 2015 set the high temperature for any September on record in San Pancho: 95 F on the 7th at 4:41 p.m. But wait, there’s more.

The record September high reading of 95 F is also the All-Time-High Temperature on record at the San Pancho Weather Station since it went online in 2008! The previous high was 94.2 F in June 2014. But wait, there’s more.

The average high temperature for the year 2015 is already at 90.55 F. A degree higher than any previous year. A full degree higher than last year. Global warming? Too soon to tell. We’ll need the October through December high temps to determine the actual average high for the year. But wait, there’s more.

The high Heat Index reading set a record for any September at 118.8 F. That’s second only to the all time high heat index of 119.6 F in July 2014.

In the rain department, our annual precipitation is now at 36.33 inches, a bit below annual average of 42 inches per season since 2008. There were 17 days in the month with measurable rainfall (>.04 inches). Total rainfall for the month was 7.46, below the average of 12 inches for the month since 2008. The least rain in any September since 2008? It was 2.81 inches in 2011. The most rain in September: 28.24 inches in 2010.

On the evening of September 25 a cold front moved through San Pancho between 8:10 and 8:15 causing a double digit temperature drop from 87.49 F down to 77 F In just five minutes! High winds and some rain followed, bringing some welcomed relief to San Pancho residents. Hopefully a precursor of cooler days ahead as we celebrate San Pancho Days!
