Writer's Note — Maria Volkov

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.

Climate Insights from Our Writers

“There's something about Hong Kong in autumn that the summer crowds never experience. October and November bring 25°C temperatures, low humidity, and clear skies — and the city exhales after the typhoon season. I've hiked Dragon's Back in November and the South China Sea sparkled below, the air clear enough to see the distant islands. Hong Kong's climate is subtropical, with hot, humid summers and mild, drier winters, but the real story is the typhoon season that runs from July through September. I've studied the typhoon data carefully and found that Hong Kong averages about six tropical cyclones per year, with direct hits occurring every few years. The city's response to an approaching typhoon is one of the most impressive displays of organizational efficiency I've observed — the Hong Kong Observatory issues detailed warnings, the city secures its infrastructure, and the population adapts with remarkable calm. The summer months are the most challenging, with temperatures averaging 31°C, humidity pushing 90%, and the air quality often deteriorating. The urban heat island effect is intense, with the dense high-rise development creating temperatures that can be 3-4°C warmer than the surrounding countryside. The best time for a visit is October through December, when the weather is most comfortable and the city's outdoor attractions — the Peak, the waterfront, the islands — are at their most accessible. The spring months of March and April are also pleasant, with temperatures around 20°C and lower humidity. For travelers, the key is timing — avoid the summer months unless you're prepared for heat and humidity, and plan your visit around the autumn window when Hong Kong's climate is at its most accommodating.”
