There is a reason millions and millions of people live in Mexico City, it’s very hospitable to human life. Everyday is basically perfect — I can’t remember a single day in the last two years where the weather was truly bad. It just varies a teensy bit in temperature, humidity, wind and sun levels throughout the year, thanks to its high elevation in the tropics (it’s the best of both worlds).
Right now is the rainy season, which is my favorite. The humidity is a bit higher than normal, making it easier on the skin and the lungs. The temperature never gets higher than 75, nor lower than 55. The sun shines all day, while clouds slowly build in the late afternoon; it sometimes rains at night. The air is clean, crisp and comforting. You can wear a sweater or a tank top and be comfortable either way. Meaning, it’s an absolute paradise (while lowland Mexico is a steam room this time of year).
Plus, stuff blooms. Like crazy.
