Shenzhen’s climate is shaped by its coastal location in southern China, resulting in warm temperatures and high humidity year-round. The city experiences four distinct seasons, though the transition between them is subtle. Winters (December–February) are mild and dry, with daytime highs around 20–22°C and nighttime lows of 10–15°C. Frost and snow are virtually unknown, and sunshine is more frequent during these months. Spring (March–May) brings rising temperatures (18–28°C), increasing humidity, and blooming parks, but also more rain and occasional fog along the coast.
Summer (June–September) is long, hot, and humid, with average highs of 30–34°C and frequent heavy rainfall due to the East Asian monsoon. July and August are the wettest months, with intense afternoon downpours and the occasional typhoon. Humidity often exceeds 80%, making the heat feel more intense. Autumn (October–November) is considered the most pleasant season, with comfortable temperatures (20–29°C), lower humidity, and clear skies. Throughout the year, Shenzhen receives about 1,900–1,930 mm of rain and roughly 1,800–1,850 hours of sunshine. Winds are generally light to moderate (10–18 km/h), but can be stronger during typhoons in summer.
