If you’re looking to stretch your travel budget, the off-peak months are your best bet. The low season, from June to November, is when you’ll find the cheapest flights and hotel rates. Though it’s the rainy season, the showers are usually brief, and the beaches are much quieter. Plus, Hainan’s resorts often offer discounts during this time.
Why it's ideal: You’ll save a lot on flights, accommodation, and even food. Fewer tourists means you’ll have the beaches to yourself without breaking the bank.
💰Money-saving tip: Book your trip for September or October to avoid the high prices around Chinese New Year or the summer rush. Keep an eye on flash sales for early bookings, and be flexible with your dates to score the best deals.
