Lào Cai has a dry-winter humid subtropical climate (Köppen Cwa), similar to most of Northern Vietnam.

The soil in this area is poor in nutrition, infertile and subject to continuous erosion due to its slope of 7-10%.

The half hilly region surrounds a plain with an average elevation of 10 m from north-east - north to north-west – south-west and south – south-east.

[1] Ethnic minorities in Lào Cai used to speak Southwestern Mandarin and Vietnamese to each other when their languages were not mutually intelligible.

[8] Lào Cai City is officially divided into 17 commune-level sub-divisions, including 10 wards (Bắc Cường, Bắc Lệnh, Bình Minh, Cốc Lếu, Duyên Hải, Kim Tân, Lào Cai, Nam Cường, Pom Hán, and Xuân Tăng) and 7 rural communes (Cam Đường, Cốc San, Đồng Tuyển, Hợp Thành, Tả Phời, Thống Nhất, Vạn Hòa).
