Wearing Advices for September

 Essentials: Rain Gear
Undeniably, water-proof coats are better than umbrellas in the unpredictable shower days because you can still have free hands to take pictures. You can choose the raincoats according to your clothes for a better look. However, if the shower is too heavy or it is too hot and unbreathable to wear a raincoat, a light folded-umbrella is a smart option, too.
 
 Clothes: Thin and Quick-drying Pieces
Quick-drying T-shirts, tube tops, sleeveless tops, shorts and skirts come out to help keep cool during the sweating weather of Thailand in September. The choice of color should be bright to deal with the gloomy climate. Above all, anti-slip sandals with straps or rain boots can help you walk easily on the wet floor.
      

Top Experiences in Thailand in September

Sunny Hours: Explore Historical Sites in Traditional Thai Clothes

After showers, it often has drier and brighter weather, great to explore some local attractions. In Bangkok, you can visit the Grand Palace, Wat Pho temple and Amphawa Floating Market. Tha Phae Gate and Wat Phra That Doi Suthep are must-visit destinations in Chiang Mai. And in Chiang Rai, it is recommended to go to Wat Rong Khun, Wat Rong Ten, Baan Dam Museum and Singha Park.
 
To have a more impressive trip, you can wear Chut Thai, the traditional Thai clothes with complicated embroidery and sequins, while visiting these cultural sites. Don’t forget to take some unique photos against the above cultural backgrounds.
 

Rainy Days: Try Thai Massage, Watch Thai Performances and Taste Thai Food

If the shower is too heavy to visit the outdoors attractions, you still can enjoy yourself with unique Thai experiences indoors.
You can find a Thai massage store to massage your shoulder or feet. In many hotels, there is also massage service for you. It is a good way to release the tiredness of the trip.
 
Another interesting thing to do in rainy days is watching unique Thai performances. As we all known, lady-boy show is a trending performance in Thailand. The lady-boys wearing delicate costumes perform all kinds of traditional dances of Asian countries and Broadway-style musicals. The most famous ones are Calypso Ladyboy Cabaret Show in Bangkok and Tiffany Show in Pattaya. Besides that, you can watch Khon (masked dance drama) to experience the traditional Thai arts or see Muay Thai shows to feel the strength of Thai boxing.
 
Last but not least, try authentic Thai food. Kaeng Khiao Wan (Thai style green curry) and Phat Thai (Thai style fried rice noodles) are the signature dishes of Thailand. You should also not miss delicate Thai sweets such as Ta Koh (coconut milk pudding with Pandan leaves) and Luk Chup (mung bean dessert). What’s more, Thai drinks like Cha Yen (Thai Milk Tea), coffee and fruits juice with special plastic packing bag is the best choice to relive heat.
