Writer's Note — Maria Volkov on December

There's something about Hong Kong in autumn that the summer crowds never experience. October-November brings 25°C, low humidity, clear skies — and the city exhales after typhoon season. I hiked Dragon's Back in November and the South China Sea sparkled below. Summer is a different beast: 33°C with 90% humidity, the air thick enough to chew. Typhoons (July-September) are dramatic cultural events — shops shutter, signals fly, everyone watches the news. Lunar New Year (January-February) brings a festive energy despite the 16°C chill. Spring is humid and gloomy; autumn is the city's gift to itself.
