April – A Hot Time in the Old Town

April was unusually warm, no, hot for San Pancho. Temperatures and humidity were above average.

Usual humidity readings at our seaside village on the Riviera Nayarit are around 75%. This April we hovered around 85%, often reaching 90% or better.

The high temperature in town last month was 84.7 F which was lower than April of last year when we had a high of 87.5 F. Most April highs are in the low to mid 80s.

If you were with us, it felt more like June than April. It just felt very hot with the April heat index peaking at 96.8 degrees one day. A comparable June Heat Index would be in the 105 degree range!

Looking ahead to the rest of May, based on past records, expect high temperatures in the mid to upper 80s, the Heat Index to be in the mid to upper 90s and a 50/50 likelihood of some rainfall, but probably in the range of .50 to .75 of an inch for the month.

We’ve been wrong before.

Never Say Never

Never is a very long time, especially when it comes to the weather. Six years of weather data is certainly not never. In spite of that insight, based on six years of records at the San Pancho Weather Station, yours truly promised no rain for the months of March and April 2015. Wrong.

Early March opened with just over two inches of precipitation in three days in San Pancho. Puerto Vallarta had more than three inches and the Sierras even more, flooding arroyos and rivers alike. Most humbling for me was I had guests in town for the rain after promising them it was the picture perfect time of year to visit the Rivera Nayarit.

Going back to 2009 there is no rain on record for April in San Francisco, Nayarit. So that makes it unlikely that we’ll see rain this month. That’s not an April Fool’s Day joke. But it’s not a promise. I’m staying out of the prognostication business for a while.

The high temperature for March 2015 was 86.6 F, slightly above average. The low was 59.8, also slightly above average for the month. Looking forward, April will bring highs in the mid-80s with lows around 60. Rain very unlikely! If the past is any predictor of the future.

But, it may not be.

It’s Not Over Yet

Monday morning and the rain continues in San Pancho. Light rain could continue through tomorrow.

In the last 24 hours we’ve had 2 inches of rain and temperatures are in the mid-60s. A huge low pressure system covers all of Central Mexico, coast to coast.

For those celebrating the long holiday weekend the weather has been disappointing.

For the record books, it’s the first real rainstorm we’ve had since 2009, an all time record for the San Pancho Weather Station.

How do I explain this to my guests who arrive this afternoon?
