Travel tips
Seasonality, packing, local etiquette, food and water safety, and essential contact numbers.
When to visit
Hainan’s tropical monsoon climate is warm year-round. Nov–Apr is peak season for visitors escaping colder inland winters; May onward is quieter with softer hotel/airfares. Summer brings clearer seas and abundant seafood — each season has its own appeal.
What to pack
Breathable, quick-dry clothing and a ventilated bag; SPF 40+ waterproof sunscreen; meds for heat, stomach upsets, and mosquito bites; swimwear, towel, and flip-flops (some hotels provide towels/slippers).
On-island know-how
UV is strong even in winter — sunglasses, sunscreen, shade, and hydration matter. Bargain politely for seafood/fruit and watch weights; use consumer hotlines if needed.
Inventory room items on arrival; don’t open the door to strangers. Avoid calling female staff “小姐” (local slang risk) — “小妹” or “阿姨” is safer.
Don’t overeat seafood or tropical fruit; skip cold drinks/watermelon within an hour of seafood, and don’t swim immediately after heavy meals. Follow staff and wear life jackets for water sports; mind tides. Keep kids supervised; travel in pairs when possible; protect valuables and the environment.
