The San Pancho Weather Station Returns

The San Panco Weather Station has been offline, but it will return. It’s one of the most often viewed sites for San Francisco, Nayarit, MX. And the good news is it could be online as soon as June. So stayed tuned and check back!

A series of technical and life events brought the station down in March. But as things can unravel they can be raveled again. The weather station will return with its full eight years of San Pancho weather data.

Thanks to everyone who has enquired about my meteorological hobby. I enjoy keeping track of our (mostly) perfect weather here on the Riviera Nayarit. It’s good to know you do too!

Cold? Not. So. Much.

January, February and March are the coldest months of the year in San Pancho. But before I scare away visitors planning to travel to the Riviera Nayarit, keep in mind I’m talking about a low temperature around 60 degrees F. Not very cold by most standards! Well, not cold by my native New England standards.

If you’re looking for cold weather in Mexico, there’s some to go around as much of the country has experienced some cold temperatures, rain and strong winds according to this article titled The Polar air mass over much of Mexico in the Sol Mexico News.

Here in San Francisco on the Riviera Nayarit, our January low was 58. 7 F compared to last year’s 59.1 F. The expected low for February will be about the same, a couple of degrees either side of 60 F.

Daytime temperatures in San Pancho in January were moderated by several cloudy days. We reached 86.7 F on January 2nd with the UV index riding high many days in the low 90’s, less than last year’s high heat index of 97.3 F.

Rainfall. None, excepting a very brief light rain mid-month. But it’s not unusual to have some rain in January. In February we can expect either none or three inches based on past records. In 2010, 2012, and 2015 we had 3+ inches of rain. The other years since 2008, only a trace of rain. Your guess is as good as mine.

Several days of massive surf was the environmental highlight of the month. The Pacific was churning out 12 foot waves that came crashing in, with the resulting strong undertow that was a challenge for even the best swimmers. The beach landscape changed daily due to the surf. Quite an impressive site at sunset.

If you’re planning to visit Mexico this season, head for San Pancho. You’ll find us just north of Puerto Vallarta. You’ll love our town and the weather can’t be beat!

A Record Breaking Month and Year

In the world of NFL football, I enjoy it when Tom Brady breaks records. When it comes to the weather, breaking old records is a mixed bag, especially when it comes to rain and hot weather. Let’s take a look at December 2015 and the full year to inspect a few new records.

Rain amounts grab our attention the most, so let’s start there. December rain totaled 3.62 inches, an all time record for the San Pancho Weather Station database (2008 thru today is the basis for any ‘all-time’ reference). The record broken? In 2009 we had 3.09 inches, well above the average of about an inch for all Decembers.

Total rain for 2015 was 48.87 inches, second only to the all-time record  of 2010 which was 55.70, well above the average of for all the years on file.

They say a picture is worth a thousand words, so to spare you the reading time, here’s the annual rainfall history in San Pancho.

The other weather observation that caught our collective attention last month and last year was the intensity and length of the hot weather. And for good reason. December was the warmest December on record: 88.4 F, besting 2013 when it was 87.8 F.

The average high temperature for the entire year was 90.45 F., a new record and a full degree warmer than 2014’s average high.

December low temperature: 62.6 F., not even close to the December 2010 low record when it was 57.0 F. That’s right in line with those warm temperatures for the whole year. The overnight low temperature average for 2015 was: 67.32 F, compared to the 62.48 F low average of 2009.

When it comes to comfort the heat index is the best indicator we have, it being a combination of temperature and humidity. The average of the high heat index for 2015 was a record 83.93 F. That beat the average high of 82.49 F. of 2014.

The December high heat index was 99.9 F. another record, besting the previous record of 96.3 F. in December 2013.

Most remarkable though is the annual high heat index average for the entire year. In other words, take the high heat index for every day last year, divide that number by the days in the year and the result is 105.84 F., a new record and higher than last year’s 103.23 F. So now I give you another New Year’s gift graphic to put this number in perspective, along with my best wishes for and healthy and joy-full 2016!
