# Canton Fair Weather Guide: Surviving Guangzhou
Guangzhou is located in the Pearl River Delta, deep in southern China. It has a sub-tropical climate.
If you pack a wool suit for the Canton Fair, you will suffer from heatstroke by noon. The weather is a massive physical factor in your sourcing endurance.
> **💡 Withyou Trip Expert Verdict:**
> "The biggest logistical threat during the Autumn (October) session is **The Typhoon Danger**. Late October is prime typhoon season in the South China Sea. A direct hit will shut down the Canton Fair for a day, cancel all high-speed trains to Hong Kong, and ground flights at Baiyun Airport. You MUST build a 1-day flexible buffer into your departure flights in October."
## 1. The Spring vs. Autumn Weather Matrix
| Session | Temperature | Humidity | The Major Threat |
| :--- | :--- | :--- | :--- |
| **Spring (April/May)**| 75°F - 85°F (24°C - 30°C) | 90% (Extremely Muggy) | **Plum Rain Season.** Sudden, torrential downpours every afternoon. |
| **Autumn (Oct/Nov)** | 70°F - 80°F (21°C - 27°C) | 70% (More comfortable) | **Typhoons.** Severe wind events that cripple transport. |
## 2. The "A/C Shock" Inside the Halls
The most dangerous temperature shift happens inside the Pazhou Complex.
* **The Reality:** It is 90 degrees and sweating outside. You walk into Hall 14.2, and the Chinese government is blasting the industrial air conditioning at 65 degrees.
* Going from extreme heat to freezing A/C back to extreme heat multiple times a day frequently causes buyers to develop a severe cold or sinus infection by Day 3.
* **The Fix:** You must pack a lightweight, breathable zip-up jacket in your backpack. Put it on when you enter the halls, and take it off before you walk outside.
## 3. What to Pack for the Rain
In April (Spring Fair), it will rain. It is not a gentle drizzle; it is monsoon-level rain that instantly floods the streets.
* **Do not bring a heavy raincoat.** You will sweat to death underneath it.
* **Bring a compact, wind-resistant umbrella.**
* **Shoe Strategy:** Do not wear suede or fabric mesh shoes if you plan to walk outside. Wear water-resistant leather or Gore-Tex running shoes, because stepping into a massive puddle in front of the taxi line is inevitable.
## ❓ Frequently Asked Questions (FAQ)
**Q: Does the Canton Fair close if it rains?**
A: Never for rain. The fair is entirely indoors. However, if the Chinese Meteorological Administration issues a "Red Typhoon Warning" (Signal No. 8 or higher) during the October session, the fair will legally lock its doors and suspend operations until the storm passes.
