Overview: 
1. Guangzhou’s weather in March becomes increasingly warm, but large temperature fluctuations still exist. Be aware of the significant temperature gap between day and night.

Guangzhou experiences an obvious increase in temperatures in March, showing the arrival of spring. Most days enjoy a daytime high of 25-29 degrees Celsius (77-84 degrees Fahrenheit). However, Guangzhou may go through shifts between sunny and rainy weather within several days, resulting in considerable fluctuations in temperature. If rain falls, the perceived temperature would drop by about 3°C (5°F). If the rain is accompanied by the cold air, the weather would be much chillier. Therefore, you need to pack extra layers for your visit to Guangzhou. You should also know that early mornings and late evenings can feel quite cool, with lows of 12-16 degrees Celsius (54-61 degrees Fahrenheit). Especially when you plan to catch a sunset view, it’s best to carry an extra layer to deal with the cool moments. Recommended sunset spots include Mount Baiyun, Pa Ti, Liede Bridge and Changzhou Island.
