Arriving Feb. 27th and looking down from the Continental flight, holes were developing in the clouds and as the mountains peeked through, they were white. Overnight and early morning snow had blanketed everything down to 2500' or lower. On the ground the temperature was above freezing, and isolated rain and snow mixed showers drifted across the valley. That night the temp dropped below freezing. A month earlier, a 100 year freeze had settled in for several nights and killed many plants, cactus, and palms. Most of my balcony plants died too. 72 hours after landing over snow cover mountains the temperature was pushing 80F. Incredible. That day I checked the temperature in Progreso. It was about 80F there too, but the big difference is the relative humidity. Tucson was a dry 15%, while Progreso had a muggy 67% relative humidity. That is the difference between comfort, and in my case, a poor disposition. Comfortable temps along the northern Yucatan shore in the winter are in the low 60's nights, and low to mid 70's days, with a good north or north-easterly breeze coming off the sea. Perfect for me. For spring and fall, the Sonoran Desert is an excellent place to live. Just not summer.
