One thing I found out recently was just how different North Florida is from South Florida. I was quite blown away actually how much it changes over such a short distance. For example Jacksonville is a mere four hours drive to West Palm Beach and only 475km yet they are almost different worlds climatically especially in winter. Jacksonville in Winter gets fairly cool winter lows while West Palm Beach and Miami are almost 10°C warmer. Jacksonville gets winter highs in the late teens to 20°C while West Palm Beach gets winter highs in the mid to late 20's. As someone who isn't very knowledgeable on the US climate I have to say i was very impressed when it was pointed out. There is a 7°C Mean temperature difference between Jacksonville and West Palm Beach in winter. That's like Northern Europe to Southern Europe lol. It's even greater than the difference between Brisbane to Townsville which is fifteen hours drive and 1370km difference lol. Are there any other climates like this that are both oceanic on the coastline, on a relatively similar altitude yet also significantly different in such a short distance?

Coastal Vietnam sees a similar dynamic. Winter temps quite different. In Jan, Saigon has a higher low than Hanoi has a high

I don't know if there is a "yes" answer to your question. I wouldn't say Florida has a true tropical climate though, except for somewhere like Key West.
Just discovered that Hong Kong has slightly warmer winters than Ha Long, Vietnam.

It's just what really impresses me with Florida in particular is that the difference between these two climates is a mere 457km. Similar to the distance between Newcastle in England to London. Hanoi and Saigon are over 1700km apart. One could leave Jacksonville in a 5°C winter morning and drive to West Palm Beach and 4 hours later be in a completely different climate that is now Tropical. Just seems surreal to me. Pretty interesting

As far as the tropical-subtropical gradient is concerned, I don’t think this is that rare. Similar temperature gradients can be found on the Sea of Cortés coast in México, in SE South Africa, and SE Brazil.

West Palm Beach Airport is about 2 miles from the ocean, while Jacksonville Airport is closer to 8 miles from the ocean. Furthermore, the Jacksonville Airport is on the north side of the city and probably experiences less urban heat island effect than West Palm Beach. Furthermore, West Palm Beach is on the peninsula, whereas Jacksonville is more connected to the rest of North America.
Brownsville and Sugar Land, in Texas, have a similar difference in average temperature over similar latitudes. Not quite as extreme, but I think the differences could be explained by what I mentioned previously.
At mid-latitudes the temperature gradient is similar. Kansas City, MO is 6.4°C colder than Fort Smith, AR, and they are 505 km away by car.
It is interesting you found a slightly stronger than average temperature gradient, but it's not outside the realm of typical North American winter temperature gradients. It is good at challenging the stereotype of all of Florida being hot all year.
