Best Time for Families with Kids
From our July 2025 trip with two kids (ages 11 and 13), here’s what we learned:
Cool season (Nov–Feb) is the most comfortable for outdoor sightseeing.
Rainy season can be fun if you plan more indoor activities (museums, malls, aquarium).
Always stay near a BTS Skytrain station for easy transport – see Best Ways to Get Around Bangkok with Kids.
Best Time for Festivals & Events
Some of Bangkok’s most unforgettable experiences are tied to its festivals:
Songkran (mid-April) – Thai New Year water festival.
Loy Krathong (Nov) – rivers and lakes lit up with candles and lanterns.
Chinese New Year (Jan/Feb) – dragon dances in Chinatown.
How Exchange Rates Affect the Best Time to Visit Bangkok
It’s not just the weather and festivals that influence the best time to visit Bangkok—exchange rates can make a big difference in how far your dollars stretch.
Stronger USD = Cheaper ThailandWhen the US dollar is strong against the Thai baht, your hotel, food, and transport costs drop significantly. For example, in August 2025 the rate was around 1 USD = 35.7 THB (Bank of Thailand data). That meant a $100 hotel night cost about ฿3,570 instead of ฿3,300 the year before.
Off-Season + Favorable Exchange Rates = Double SavingsIf you travel during the low season (Sep–Oct) and the USD is strong, you can easily save 30–40% on accommodation compared to peak months.
Practical Tip: Use a multi-currency travel card (like Revolut or Wise) to lock in good exchange rates and avoid ATM fees in Bangkok.
