Florida temperatures finally cool; La Niña officially underway

The torrid pace of record-breaking heat in South Florida seems to have slowed this month. Thursday’s temperatures in West Palm Beach, for example, were dead-on average, with a high of 82 and a low of 65.

It’s no wonder that many people consider this the nicest time of the year, along with March and April.

Friday morning’s low at Palm Beach International Airport was a refreshing 62 degrees, with a dew point of 60, and I imagine there were few complaints from residents when they stepped outside with their morning coffee.

The Forecast highs in West Palm Beach over the weekend are in the upper 70s with clear to mostly-sunny skies, so a trip to the beach may be in order after a walk or a run, and maybe a little yard work.

The normal high in West Palm Beach slips down into the 70s a week from Sunday, with a normal low in the mid-60s, so Chamber of Commerce weather most likely will continue to hold as we move toward the holiday season.

The new long-range Thanksgiving Day forecast from AccuWeather is for a high of 81 and a low of 65 under mostly cloudy skies.

It’s here! It’s here! La Niña conditions officially arrived in the tropical Pacific, NOAA’s Climate Prediction Center said Thursday. The agency issued a La Niña Advisory.

Weak La Niña conditions are forecast to continue through February, forecasters said, but they added: “At this time, the consensus favors La Niña to be short-lived, with ENSO-neutral favored beyond DJF [December/ January/ February].”

La Niña tends to bring warmer and drier winters to Florida. NOAA will update its winter outlook next Thursday, Nov. 17.

Climates already in a warming phase are more sensitive to increases in CO2 levels, according to a new study by the University of Hawaii at Manoa.

The conclusions, published this week in the journal, Science Advances, were based on historical research from ice core samples resulting in a look at global mean temperatures over the last 784,000 years.

“Our results imply that the Earth’s sensitivity to variations in atmospheric CO2 increases as the climate warms,” said Tobias Friedrich, of the International Pacific Research Center (IPRC).

“Currently, our planet is in a warm phase—an interglacial period—and the associated increased climate sensitivity needs to be taken into account for future projections of warming induced by human activities.”

Based on data collected from the past, Friedrich and colleagues projected that global temperatures will rise by about 10.5 degrees by the year 2100.
