it's basically a promontory, so, not surprising

this island is a large promontory in every direction with specific tendencies of heat and humidity... on the north side it rains a lot in autumn and spring, and is mostly cloudy, on the south, same rain schedule but is mostly sunny

temperature difference between north and south is several layers of clothing on this little island, i experienced this in march with the bitcoin atlantis conference. literally drizzly fog when i left and almost singlet weather on the south. in "winter"
