When planning a trip to Guangzhou, it is important to choose the right wardrobe to feel comfortable in any weather.

It is also worth taking a small backpack for day excursions to hold water, sunscreen, and other small items.

The summer months in Guangzhou, roughly from May to September, are characterized by high temperatures (average maximums often exceed 30°C) and significant humidity, as well as frequent and sometimes intense rains, especially from April to September. During this period, choose light, breathable clothing made from natural fabrics such as cotton or linen: t-shirts, shorts, skirts, and sundresses. Be sure to bring sunscreen with a high SPF, a hat, and sunglasses. A sturdy umbrella or a light waterproof raincoat will become your faithful companions. Open but comfortable footwear that dries quickly will also be appropriate.

Although there is less rainfall in autumn, a small umbrella still wouldn't hurt, especially at the beginning of the season.
