3. Extreme Weather Conditions

Hong Kong experiences extreme weather events, particularly during the summer months. These include:

Typhoons:

  • Typhoon season runs from May to October, with the highest risk in July and August.

  • Preparation Tips:
    • Stock up on non-perishable food, water, and batteries during typhoon season.

4. Practical Advice for Adapting to Hong Kongโ€™s Climate

Clothing and Accessories:

Home Adjustments:

  • Air Conditioning: Essential for summer. Ensure your rental property has functioning air conditioning units.
  • Heating: Portable heaters (HKD 300 to HKD 1,000) may be needed in winter, as central heating is uncommon.

Health Considerations:
