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!

Was August really that hot and humid?

Yes. It was hot, humid, rainy. Big time. Muggy. Oppressive. Pick your favorite word.

August 2015 goes down in the record books!

Highest temperature ever recorded at the San Pancho Weather Station: 94.8 F.

All time highest average Heat Index for any month on record: 94.1 F. (Last July’s average, the previous high average, was only 92.9 F.)

Second highest Heat Index reading on record: 117.1 F. (Previous high was July last year at 119.6 F.)

A handful of rain events netted nearly 12 inches of rain for the month, an average amount. That doesn’t equal the 14 inches in August of 2010, which was followed by the 28 inches of rain in September 2010, the all-time rainfall record. As in our San Pancho bridge washing away.

The heavy August rain storms finally caused the river to break through to the Pacific. What to expect for September? There will be significant rain as the annual rainfall for this year stands at 30 inches. The average yearly amount is about 40 inches, possibly more.

Relief in sight? Sure, as average high temperatures for September and October moderate to the low 80’s, it will cause  flocks of snowbirds to return to our sunny spot on the Riviera Nayarit. Look ahead. Our fabulous weather and gorgeous days are just a few weeks around the corner.

Easy for me to say.

Rain Update – July 29

As my July posting went on line last night, the rain started gently coming down on San Pancho.

An inch and a half of it, bringing the monthly total to nearly 7 inches, the average for July rainfall amounts. What the San Pancho Weather Station couldn’t record was the spectacular and local lightning and thunder show, certainly the biggest of the season.

Most of the rain fell between 4 and 5 a.m., at one point coming down at 6.5 inches per hour.

Now that’s my kind of rain. It’s a leak-finder rain. If you thought you had all of the leaks in your apartment or home fixed, this is the kind of storm that will find one (or two or three) more!
