I actually know that too re: latitudes, climate and microclimates. I get so impressed with having a palm tree in my front yard that’s now substantially taller than my house. It blew me away that this far north, it was even possible. But I am at, or very near sea level - maybe 5-10 ft elevation at mi casa, and am close to the water. It can snow across town, but we’ll get none here.
We also like to take beach vacations in Hawaii, and go to most of the islands, depending on time of year. They have microclimates over there, like nowhere else I’ve ever been. Pretty amazing what even 10 miles north will do, time of year, and with a lot of variation, island to island. And of course the leeward or windward side of the islands is a huge factor.
Wish we’d known it sooner, but beach vacations in N. and S. Carolina in the early fall were a revelation. Could never understand how people could swim off Cape Cod either. The Gulfstream, as my Bostonian hairdresser told me, as well as @Auspicious helpfully reminding me of it also.
Our waters here on the left coast are COLD, but of course, we get warming air currents. A barracuda was even found recently in our cold, deep waters, most likely due to climate change.
BTW, the resident palm tree, a Mexican Fan Palm survived a severe ice storm about 25 years ago, when it was only about 2 feet tall. It was planted close to our house, which helped, but we also covered the base of it as well as possible, with plastic, burlap and blankets. The Windmill Palm in the back did not survive. We lost power, heat and water, for about 48 hours too, as a couple family members were recovering from the flu, and I was pet sitting a bird, as well as caring for our cockatiel. Turned on the gas fireplace, let it burn constantly, placed the bird cages a safe but close distance to the heat. Heavy blankets on their cages. We had to layer up and congregate by the gas fireplace, huddled under down comforters and heavy blankets. Thank god for our gas stove and ability to cook. BTW, we all survived, including the birdies.
