Hmmm, that depends on what your definition of “hot”…or “cold”…is…
Ecuador has four “regions” — Sierra (or mountains), the Oriente (Amazon basin), the Coast, and the Galapagos. I doubt you would choose to live in the Galapagos or the Oriente, so that leaves the Sierra and the Coast.
Sierra weather is, day in and day out, like Colorado mountains in the SUMMERTIME (we’re on the equator so we don’t have winter.) We live in Cotacachi in northern Ecuador at 8,000 ft. elevation and it’s perfect for me, (70F to 75F during the day and 50F at night) but some find it “too cold.” You’ll find much the same weather in Quito and Cuenca. If you think it would be too cold for you here, I’d suggest you check out Loja or Vilcabamba. They’re at lower elevations (4500 ft.) and therefore warmer.
Along the Coast, climates are fairly temperate, but you’ll find it gets hot and humid November – February. And weather patterns can vary along the coast – -you’ll find pockets that get more sunshine than others, thanks to the Humboldt Current that flows up from Peru.
