Cities are decorated with blue flags, jasmine flowers, and glowing lights, especially around Bangkok’s Grand Palace and Ratchadamnoen Avenue. In the evening, locals take part in candlelit ceremonies to honor the Queen. At home, children give jasmine garlands to their mothers in a heartfelt gesture of love and respect.

By late August, riverside towns like Nakhon Phanom kick off the long-boat racing season. Teams of rowers compete in narrow, colorful boats along the Mekong, cheered on by excited locals. The riverbanks transform into festive markets, with food stalls, music, and handmade crafts.
Helpful Tips for a Trip to Thailand in August
What to Pack for Thailand in August
August is warm and wet, so bring breathable clothes, a light rain jacket, and sandals or shoes that dry quickly. A small umbrella or foldable poncho is great for sudden downpours. Quick-dry fabrics will be your best friend.
How to Plan Your Itinerary Around Rain
Rain often falls in short bursts, usually in the late afternoon or evening. Try to schedule outdoor activities earlier in the day and leave room for changes. Keep a few indoor options, like temples, museums, or cafés.
Transportation Tips During Rainy Season
Thailand’s transport system works well, rain or shine. In cities, use apps like Grab (for taxis) or ViaBus/Moovit (for buses and MRT/BTS in Bangkok). For intercity travel, trains and buses are budget-friendly, while domestic flights are cheap and fast. On islands, songthaews (shared trucks) and scooters are common, but avoid riding in the rain unless you’re experienced.
How to Stay Connected in Thailand (SIM & Wi-Fi)
Buy a Thai SIM card upon arrival (AIS, DTAC, or TrueMove are top choices). You can get one at airports or convenience stores. Choose a package with data so you can use maps, translators, and ride apps on the go. The signal is strong in most places, even in rural areas.
Money Tips for Travelers in Thailand</h3
Thailand’s currency is the Thai Baht (THB). Cash is still king in many local markets, food stalls, and small towns. Exchange money at reputable counters like SuperRich (better rates than airports), or withdraw from ATMs with an international card (watch for the 220 THB withdrawal fee). Bring some small bills for tuk-tuks, tips, and street food.
