November by the Numbers

Rain in November is unusual in our pueblo. This has been a most unusual eleventh month of the year in San Francisco. The total rainfall was 4.53 inches (11.4 cm), more than any other other year on record at the San Pancho Weather Station. The previous high total was a modest .7 inches (1.7 cm) last November. Every other year it was only a trace amount.

Lest you think that’s the end of rain for the calendar year, it might not be. The record books show we had 3 inches (7.6 cm) last December of and again in 2009. Other years had only a trace. With six years on record, I’d say we have a 30% chance of rain during the holiday month. Hopefully it won’t occur at the end of the year.

The high temperature for the month was 92 F (33 C) just a few days ago, November 27. The high heat index was 102.8 (40 C) on November 7.

For those of us who thought summer would never end (until the rains came), this year is on the way to being the warmest we have on record with the annual average temperature (average all the days in the year) of 78.7 F (26 C), a full degree more than any other year. Cooler temperatures in December might destroy that record, so we’ll have to wait to see.

Low temperatures for November dipped down to 58.6 F (15 C) on November 28, a virtual tie with the low for the year recorded back on February 28 when it dipped to 57.9 F (14.3 C), the all-time low in San Pancho.

In the future, expect daytime high temperatures in December to be in the mid to low 70’s F (23 C). Our San Pancho low early morning temperatures will be around 60 F (15.5 C), though the past two years have been above that mark. Early morning low readings will be chilly, but it is hard to predict.

December 2013 only got down to 66 F (19 C) and 2012 the low for the month was 62 F (17 C). From 2009 to 2012 the low temperatures ranged from 57 F (14 C) to 58.6 F (15 C), and we’ve already been down in that range this year. So I’ll let you do the low temperature forecast for this month. You can bank on temperatures not lower than the mid to upper 50’s (14 C). A light blanket or good friend will do.

We will have no frost days. No wind chill temperatures. No wind more than 15 mph (24 kmh). And a reasonably good chance of no rain days.

Look up! Whether your outside during the day to take in San Pancho’s beautiful blue skies or at night when it seems you can see the entire universe on a clear night, look up, smile and enjoy! You’re going to love December in San Francisco, Nayarit, Mexico – on the Riviera Nayarit.

Four Inches of Rain in November

This is a lot of rain for November. With today’s rainfall we’ve had  more than four inches for the month!  It’s an all-time record! The previous record? About three quarters of an inch last year. All other Novembers had only a trace.

The low pressure system about 250 miles west of San Pancho is producing the rain, which is expected to continue through tonight. There is virtually no chance of it becoming a hurricane.

It’s interesting to note that we have had nearly four inches of rain in some past Decembers.

While things have finally cooled off in San Pancho, 71 degrees this morning, they sure haven’t dried out! If you are here on vacation, our apologies!

October Observations from San Francisco, Nayarit, MX

October Heat: High temperature for the month was 92 F, right on target with previous October highs. The high Heat Index was 113 F, just slightly above average. Nevertheless, we have had the longest and most uncomfortable (heat index) summer that started this year in May instead of June. I think its over!

October Highlight: More than four inches of rain brought our annual total in line with the average rainfall for previous years, around 40 inches. Annual total through October 31: 38 inches.

2014 Hurricane Season: Tropical Storm Vance has formed hundreds of miles south-southwest of Acapulco. There’s a slight chance this storm might bring rain to San Pancho mid-week. Check the NOAA/Hurricane link on our home page for the latest.

The End: The official end of the hurricane season is November 30. It’s not that unusual to have tropical events in November. Recent examples:

2013: Nov 1 – 4  Tropical Storm Sonia. There were reports of heavy rain and flooding in Mazatlan and Culiacan.
2012: Oct 30 – Nov 3 Tropical Storm Rosa
2011: Nov 19 – 25 Hurricane Kenneth
2010: Sep 22 – 23 Tropical Storm Georgette

Of course September 2010 was San Pancho’s record-setting, bridge washing away rainiest month on record. But Georgette wasn’t involved. None of the above storms brought any significant weather events to our pueblo here on the Riviera Nayarit.

Some great storm maps: If you search the NOAA files, you’ll find fabulous maps of the Eastern Pacific hurricane tracks for every year. A great way to refresh your weather memory! The hurricane tracks for last year are below, shown in graphics for the first and second half of the season.

San Pancho Dresses Up: Just in time for All Saint’s Day, all of the planters along Tercer Mundo have been repainted. Love them or hate them, they look much better! And all the kids in town dressed up for trick or treating on Halloween night as adults began work on altars that will adorn the Plaza on Sunday, All Soul’s Day. It’s good to see the indigenous traditions continue alongside our imported customs!
