El Niño Winter

Welcome back to #TravelThursday. Exactly 22 weeks ago I wrote about the impending El Niño Winter which had already gotten off to a strong start with severe weather and record-cold temperatures so early in the season (middle of October).

We’re now on the other side of that quite unusual winter season, and I have the final report right here.

This actually made national news early in February: It was apparently the cloudiest / gloomiest December and January in modern recorded history in Central and South Florida. (Records go back to 1941.) Cloud cover was about 70% of the time during those 62 days – almost double the average percentage.

It was also a consistently chilly winter season – but not record-breaking. In fact – it was quite an “average” winter season as far as temperatures were concerned – with no extremes. Here in South Central Florida – 40s in the morning were very common – more common than normal – but 30s were rare – mostly confined to pockets of North Central Florida. Here in Sebring – we had no 30s at all, but we had 38 mornings in the 40s. (This is actually the first winter season that I’ve personally collected weather data for Sebring, so I can’t compare that to previous seasons.)

Mornings in the 40s by month:
November = 3
December = 8
January = 14
February = 12
March = 1

We also had 22 days where we were stuck in the 60s. Combined – we had 60 days and nights with highs in the 60s or lows in the 40s. Those are called “cool” days, and they represent the number of days where the temperature did not reach 70°F plus the number of nights where the temperature dropped below 50°F.

While I was living down in Homestead Florida (South Miami-Dade County) – I was used to about 15 “cool” days per winter season (usually about evenly split). This season – Homestead recorded only 4 “cool” days – all days just below 70°F. For the first time in modern recorded history – no 40s were recorded during the entire winter season, but there was an abundance of early-morning temperatures in the 50s (more than normal). Excessive cloud cover prevented maximum radiational cooling, and that kept many of the usual 40s from occurring.

Rainfall-wise it was a little wetter than normal during the peak of our dry season (7 months in South Florida / 8 months in Central Florida). In fact – some portions along our immediate Gulf Coast actually received more rain during this El Niño Winter season than they did during the rainy season last summer. El Niño has actually ended an extreme drought along the coast.

It was a strange winter season due to a strong El Niño. It was the strongest El Niño since the strongest one ever recorded 8 years ago at the end of 2015. It’s now starting to wane, and perhaps we’ll get a La Niña develop before the end of the year. Some forecasters believe that a La Niña could even develop as early as this summer, but I’m thinking that it’ll be a slower transition from El Niño to Neutral to La Niña during the rest of this year.

Want to learn more about El Niño (and La Niña) ? The NOAA does a very good job of explaining it here.

Next #TravelThursday – I’m on the road again on a trip that’s nearly 40 years in the making. Hopefully the weather cooperates. Let’s keep traveling together.
