June Was Hot in San Pancho. But Unusually Hot? Not.

This is the hottest June San Francisco, Nayarit, has on record! Not.

Where’s the rain? We usually get a lot of rain every June in San Pancho. Not.

Nope. Both statements above are not true. I’d agree with you if you’re just sayin’ it felt that way!

Let’s start with how hot it has been feeling here in our village by the Pacific. Compare the temperatures F. for this year/last year, 2015/2014:

High temp: 93.5 / 94.2

Low temp: 75.2 / 74.3

Average monthly temp: 83.2 / 83.4

So June 2015 is just about the same as June 2014. But here’s the difference: compared to every other June from 2008 to 2013, this year and last are the two warmest on record. That average monthly temperature, an average of all the hours of the entire month (not a temperature we ever actually experienced), but that average is usually around 70 degrees, not 74 or 75.

The same pattern holds true for the Heat Index (some call it the Humidex, a “feels like” reading much like the wind chill reading).

Here’s the comparison for last year/this year, 2015/2014 for the Heat Index:

High Heat Index: 114.9 / 114.0

Average monthly heat index: 91.4 / 92.3

The high heat index for every other June on record is around 102. And the average monthly heat index for years previous to 2014 is 84. There’s no doubt about it, this June in San Pancho was feeling very hot, very humid…more than any year except last year.

So if this year was the same as last for temperatures and the heat index, why don’t we remember things that way? The missing ingredient here is rain. Once you add that factor, you’ll realize why we don’t remember how how last June was. It was a very rainy June.

We here at the San Pancho Weather Station track how many days of measurable rainfall we have. The number of days with rain for all the June months on record since 2008 is 10. This June it was 7 days with at least a trace of rain. In 2014 it was 17. That’s second only to the 18 days of rain back in 2008.

Total rainfall this June was 4.85 inches, all in the early part of the month. In 2014, with 17 days of rain we had 11.84 inches of rain!

July promises a double-digit number of days with rain and a rainfall amount sure to exceed the five inches of June.

Distracted by the rain last year, we forgot the hot. Providing further proof of the old axiom that we can always find something to complain about when it comes to the weather. And that’s OK. Mother Nature doesn’t take it personally.

The Rains Arrive

Thunderclaps and lightening from the south. The dogs running for cover. And it looks like the remaining minutes of May are the beginning of the rainy season.

Could be we’ll only have a tenth of an inch or or two of rain, but enough has fallen to give the feeling of a real change. After two months of hot and humid weather those of us in San Pancho are ready for the rain. Natives and visitors alike.

To keep track of the accumulation, keep your eye on the home page of http://www.sanpanchoweather.com . Updates are posted about every ten minutes.  

It may not be much of a storm, but I think it’s safe to say the rainy season has shown up here on the Riviera Nayarit.

May Be Hot

The North Beach at San Pancho, Mexico

The merry month of May was a humid and hot month of May in San Pancho this year.

Conventional wisdom around town was that it was hotter than previous years and that’s true. I also think that those of us staying for the beginning of summer got it early and were tired of it already sensitive to it because the warm weather really started in June.

The high temperature for May (as of this writing, the 28th) was 92.4 F, 1.5 degrees warmer than last year and five or more degrees above a “normal” May. Overnight lows were slightly cooler, resulting in an average daily temperature of 79.3, just about the same as last year, but 3 to 5 degrees higher than any other May on record (2008-2014).

Maximum Heat Index reading was 103.1 F, exceeded only by last year’s 108.5 F. All other years were 100 F or below. The average daily heat index was 82.7 F, with last year’s 86.1 the highest on record. Normal range is 77 to 80 F.  I guess we’d all forgotten how hot last May felt. As I’ve mentioned here before, our memories are very good at recalling weather conditions unless it’s a major weather event like a hurricane.

This year we had the unusual event of rain in March…2 inches…in a month that has no other rain recorded since 2008. April has no rain recorded since 2008. And we’ve made it through May (as I write this) without rain, while north of us Texas and Oklahoma have been drenched. Usually May brings a half to three quarters of an inch. Half the time. May 2013, 2011 and 2010 had no rain.

Standby for June rain here on the coast, anywhere from 2 to 12 inches. Last year: 11.84 inches (remember that? I don’t!).  We’re more likely to have precipitation in the 2 – 5 inch range.

The official beginning of the 2015 Hurricane season started mid-month and runs through the end of November. Depending on which predictions you read, it could be a busy season. Or not. Seems the consensus is for two or three significant storms of hurricane strength for the Eastern Pacific Region. In any case, May 24-30 was the official Hurricane Preparedness Week in the States. Bottled water, flashlights, portable radio, etc. It’s not a bad idea anytime of year here in San Pancho by the sea.

Here are a few useful and informative links if you’d like to prep yourself for whats to come, including the list of names for 2015. There are actually six of these lists and NOAA rotates through them again after every six years. The first named storm of the season, Andres, is already out there in the Pacific and is expected to remain well out to sea.

These are the links I found in a brief and I’m sure you can Google™ many, many more. I’ll keep them posted on the San Pancho Weather Station home page so you can refer to them during the summer.

National Hurricane Center – the motherlode of information assembled by NOAA at the Miami Hurricane Center. BTW: the National Weather Service email subscription service was discontinued due to “physical challenges” in 2013, so don’t bother looking for a place to subscribe anywhere on the NOAA site. NOAA was paying a private company to email the alerts. (Is managing a mailing list something beyond the pay grade of people at NOAA?). I’m checking some private links that have picked up the alert information and are delivering it without cost. I’ll get back to you on this.

National Hurricane Center Twitter account – for those tweeters out there

Stormpulse – One of the more attractive and easy to use storm tracking sites with an archive for each tropical storm

Weather Channel – great article about the impact of our Eastern Pacific storms on the US mainland

Eastern North Pacific Names – just scroll down to the six years of names list

Greg Laden’s Blog – you’ll have to scroll down for his Hurricanes in the Eastern Pacific entry, but it’s worth reading.
