2007 San Pancho/San Francisco Weather Summary

2008-01-14T14:25:00.000-07:00

It looks like 2007 was a typical weather year in San Pancho with no unusual activity to report. Though folks who've been here for some time can attest to the fact that late December 2007 (as well as early January 2008) have been colder than normal.

When my best friend and I visited SP in December 2006 and fell in love with the town, the nice warm weather Christmas week 2006 was part of the enchantment of the place ... and we decided to purchase our home after being here for only three days! But we're not looking for a weather rebate. The rest of Mexico has been having some unusually cold weather and back in our former home, San Miguel de Allende, they've had at least two freezes to date!

Some highlights for 2007 from the SanPanchoWeather Station:

The high temperature for the year was 95.6 F (35.3 C) on October 24th. The low for the year was 53.3 F (11.8 C) on the last day of the year!

Average temperature for 2007: 79 F (26.1 C). Pretty comfortable indeed. So not to complain about a few chilly nights. (OK, I'll admit it. We dug out the electric blanket a few days ago.)

Rainfall for the year was 27.5 inches (698.5 mm). Nearly all of it was recorded in July, August and September, as is the norm. Most rain in one day was on August 23rd, with 2.43 inches. Another 2.4 inches fell two days later! The only other real deluge was on September 23rd with 2.02 inches, with another 1.39 inches on the 25th. That pretty much signaled the end of the rainy season.

If you're interested in more numbers, graphs and details on last year's weather, it's all available at the Weather Underground at this page:

http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=INAYARIT2&day=31&year=2007&month=12&graphspan=year

As for the current 'cold' weather spell: our low temperature for January through the 14th was 52.3 F (11.3 C) on the morning of the 12th.

Enough already!

December Summary

2007-12-23T17:32:00.002-07:00

December looks like it will be a "normal" month, with the usual average temperatures and rainfall.

Really not much of the later. In fact, only a trace amount of rain: less than a 10th of an inch. And that's really not rain! It's actually the rain guage measuring trace amounts of water - the early morning dew. The same dew that collects on your car around sunrise. The same dew that guarantees the San Pancho dust will stick to your car for the day!

For the year, we'll have just a bit over 30 inches of rain: 30.19 to be exact.

Temperatures have certainly moderated. The low for December 2007 (through the 23rd) was 58 F (14.5C) at sunrise on the 17th. The high for December? It was 85 F (29 C) on December 1st! Clearly the temperatures of the season past!

Now we've had our full moon, the highest tides of the year, and the comforter on the bed at night. Little did I think we'd turn into such warm weather wimps that we'd need a comforter just because the temperature dipped below 60!

But then, when my son and his family arrive from New England to begin their Christmas visit with us tomorrow, I know they'll bask in our 75 degree daytime temperatures! And what a wonderful holiday gift for us to have them visit!

From San Pancho Weather, Happy Holidays, Happy New Year ... and yes, Merry Christmas!

Quiet November

2007-11-25T14:32:00.000-07:00

From the information I can gather, the average November rainfall is a little less than an inch in the Puerto Vallarta area.

We received our November rain on the 25th! Just a little more than a half an inch. The rest of the month netted only a trace (.04 inch) of precipitation.

The rainfall of the 25th occurred in the early morning hours, between 4 a.m. and 7 a.m., with the largest burst around 6:40 a.m.

Other than that, it has been an uneventful, if beautiful, November in San Pancho! And we can be fairly certain that good weather will continue through the holidays.

On the SanPanchoWeather station front, there's a possibility we might have access to a streaming video of our beautiful coastline here in town. Stay tuned!

October 2007 Summary

2007-11-01T12:00:00.000-07:00

Seems like we got the much-welcomed change in our conditions during the course of the month, with a few notable highlights.

Tropical Storm Kiko was the big attraction of the month, hovering off the coast far South of us, but not giving much of a hint of where it was headed. The good news is that Kiko decided to head West and the most we noticed was some light rain and wind activity.

The National Hurricane Center offers this in their October summary:

FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..
ONLY ONE TROPICAL STORM...KIKO...FORMED IN THE EASTERN NORTH PACIFIC DURING THE MONTH OF OCTOBER. THIS IS BELOW THE CLIMATOLOGICAL MEAN OF TWO TROPICAL STORMS DEVELOPING DURING THE MONTH OF OCTOBER...WITH ONE BECOMING A HURRICANE. SO FAR...2007 IS THE SECOND QUIETEST SEASON (BASED ON RELIABLE RECORDS SINCE 1971) BEHIND 1977 IN TERMS OF ACE...ACCUMULATED CYCLONE ENERGY...WHICH IS A MEASURE OF THE STRENGTH AND DURATION OF NAMED STORMS AND HURRICANES. JULIETTE...A SEPTEMBER TROPICAL STORM...DISSIPATED EARLY IN OCTOBER.

Second quietest storm season. That sounds good, doesn't it? For more on Kiko, check the October Tropical Weather Summary from the National Hurricane Center: http://www.nhc.noaa.gov/archive/2007/tws/MIATWSEP_oct.shtml?

October had an average humidity of 81%, but certainly that dropped off during the final days of the month. Average temperature was 80 F/27 C.

High temperature for the month was 96 F/35 C on October 24th, the low on October 28th gave us a chilly morning start at 62 F/16 C. But it was a pleasant relief.

The rainiest day? October 3rd with more than 1/2 inch. At one point in that brief storm, the rainfall rate reached more than 8 inches an hour! But that rate was momentary and the storm wasn't much longer. The total rain for October was about an inch. So I presume, newcomer that I am, we have reached the end of the rainy season for the year.

September Summary

2007-10-01T08:36:00.001-07:00

Rabbit, rabbit!

My esposa says a friend of hers from Boston said this magic incantation on the first day of each month. Supposed to bring you good luck for the new month. Rabbit, rabbit.

September was cooler than usual. That according to reliable sources who've lived in San Pancho for several years. But we had some really hot spells too, with the Heat Index reaching 107 degrees for a few minutes one day late in the month.

Rainfall? About 8 inches total for September, bringing us to 27 inches for the year to date. And one long period without rain (see previous blog entry): Sept 12 - 20. Most rain in one day? More than 2 inches on September 23rd.

Average temperatre for the month was 81.9 F . The yearly average so far is virtually the same: 82.0 F (27.8 C).

It'll get cooler now, right?

If you want more numbers and statistics and the complete database from the San Pancho weather station, here's the address at the Weather Underground:

Happy browsing and Happy October! Rabbit, rabbit.

Rainy season?

2007-09-21T10:36:00.000-07:00

The last recorded rainfall in San Pancho was very early in the morning on September 12th.

A native-born PV'er I met this week said he's never seen a rainy season so short on rain in his city.

Hmmm ... I wonder if those fixes I made to the house to prevent rain coming in will work? Will I have to wait til next year?

It's not about the weather, but ...

2007-09-17T15:56:00.000-07:00

With some folks filtering back into town this month, I've been asked if a Calendar of Events/Activities could be added to www.sanpanchoweather.com.

Of course it can with your help. And if you think it would be useful.

I'd like to limit it to community events, fundraisers for non-profits and other community activities where everyone is invited to attend.

What do you think? I'll be happy to moderate and post the information as it is received, but I'd like you opinion first.

Take a moment to complete our poll to the right. Thanks!

Significant Storm

2007-09-08T09:26:00.000-07:00

This morning's rainfall brought nearly two inches of rain to San Pancho!

It started around 4:30 am and wrapped up at 7.

Interesting to note that for a brief while at 6 a.m., the rainfall rate reached 3 inches an hour!

Any washouts at your place?

Henriette Skirts Our Town

2007-09-07T14:57:00.000-07:00

While press reports say Hurricane Henriette claimed at least 8 lives and many thousands more lost power, this latest Eastern Pacific visitor only brought us a little more rain.

Nearly an inch of rain in the first week of September, but that's behind the rate of August. And we've enjoyed some delicious sunny days and relatively cool evenings, too.

Can this be a sign of things to come? When checking out our weather site, remember to glance at the Heat Index. Even with temperatures in the upper 70s, the heavy-duty humidity can make it feel like 90 F.

Visit from Dean?

2007-08-24T15:25:00.000-07:00

It seems that part of our 3.67 inches of rain this week can be attributed to Hurricane Dean! The weather station recorded most of that during the downpour Wednesday night. The final report from the National Hurricane Center on the storm can be found below.

Wherever it came from, we now have more than 6.5 inches for the month of August. And yes, we spent a little time here mopping up after the heavy rain. I'm sure we were not alone in that activity!

---- Here's the NHC final Report on Dean ----

Rainfall for 2007

2007-08-06T14:15:00.001-07:00

Thanks to a local resident who maintains such records, I've learned that there has been only a trace of rainfall Jan - Apr of 2007.

Since the weather station began recording rainfall in May, the "12 Month Rain" starting January 1 (2007) reflects actual total rainfall. As of August 6th: 7.25 inches.

If you have further (or different) information on this year's rainfall, please contact me.

For those who took part in our first little weather "poll", thanks. Clearly, those visiting our site are a mix of folks who are in town year-round ... and those that would like to be!

The Weather Station Blog For San Francisco/San Pancho

2007-07-31T13:53:00.000-07:00

Welcome to the San Pancho Weather Blog!

We'll make note here of unusual weather events as recorded by the weather station. And we welcome comments from you with information on the weather and related topics.

As a start, I thought you'd like to know that during the heavy downpour on Sunday, July 22, the hourly rain rate reached more than 7 inches per hour. Luckily, that rate lasted for only a few minutes!

I'm still in search of rainfall information for the beginning of calendar year 2007, January through April. If you have a rain guage or know someone who tracks the rainfall amounts, please have them contact me.
