My first Shanghai summer was 38°C and 85% humidity. I thought I was going to die.
My friend from Norway moved to Shanghai in June. He had never experienced real humidity before.Day 1: 34°C. He thought, "This is fine. I've been to Spain."
Day 3: 37°C, 82% humidity. He stepped outside and his glasses fogged up instantly. His shirt was soaked within 2 minutes. He went back inside and didn't come out for 3 days.
China summer by region:
Shanghai/Yangtze Delta:
• June-August: 32-38°C
• Humidity: 75-90%
• Feels like: A sauna inside a dishwasher
• The air is literally wet. You can see the moisture.
Beijing/North:
• July-August: 30-38°C
• Humidity: 50-70%
• Feels like: An oven with occasional humidity spikes
• Better than the south, but still brutal
Guangzhou/South:
• May-October: 30-36°C
• Humidity: 80-95%
• Feels like: Breathing through a wet towel
• Summer lasts 6 months. There is no escape.
Chengdu/Sichuan Basin:
• July-August: 32-37°C
• Humidity: 80%+
• Surrounded by mountains that trap heat
• 2025: 37 consecutive days above 35°C
How to survive:
1. Never leave home without a handheld fan
Battery-powered. USB rechargeable. Buy one on Day 1. Carry it everywhere. It's not optional.
2. Plan your day around AC
• Morning: Outdoor activities before 10 AM
• 10 AM - 4 PM: Indoor only (museums, malls, cafes)
• Evening: Outdoor after 6 PM
3. Shopping malls are your sanctuary
Premium malls (Plaza 66, SKP, Taikoo Hui) have backup generators and maintain 24-26°C even during power rationing. Second-tier malls in smaller cities may not.
4. Hydrate differently
• Don't just drink water. Drink electrolytes.
• Chinese pharmacies sell oral rehydration salts (口服补液盐). ¥10 per pack.
• Coconut water, sour plum juice (酸梅汤), and herbal tea (凉茶) are better than plain water.
5. Dress for survival
• Linen or moisture-wicking fabrics only
• Dark colors absorb heat — wear light colors
• Carry a change of shirt if you're out for more than 2 hours
• The "UV protection jacket" (防晒衣) every Chinese person wears actually works
6. Your apartment
• AC is not optional. It's life support.
• Set it to 26°C — it's the sweet spot between comfort and electricity bill
• Dehumidifier mode is your friend
• Dry your laundry inside — it won't dry outside
The heat index reality:
At 35°C with 80% humidity, the "feels like" temperature is 52°C.
That's not "uncomfortable." That's "dangerous if you're outside for too long."
Heat exhaustion symptoms: headache, dizziness, nausea, excessive sweating. If you feel these, get inside immediately.
The best time to visit:
• Spring (March-May): Perfect in most of China
• Autumn (September-November): Also perfect
• Winter (December-February): Cold but dry
• Summer (June-August): Only if you enjoy suffering
My Norwegian friend's advice: "I thought I understood heat. I did not understand heat. Summer in Shanghai taught me that my body has limits I didn't know existed. Now I don't go outside between 10 AM and 6 PM. I'm basically a vampire."
Anyone else survived a Chinese summer? What's your best heat hack?
