Remember to pack a compact umbrella or a lightweight rain jacket to prepare for sudden downpours that are commonly experienced in the month.

It is also essential to pack sun protection wearing like hats, sunglasses, and sunscreen to shield yourself from the sun's rays, especially during outdoor activities.

Top Things to Do in Chiang Mai in May

1. Experience the Buddhist Festival: Visakha Bucha Day

If you are visiting Chiang Mai in May, it is wise to arrange your trip in the middle of May so that you can experience the most significant Buddhist holiday in Thailand, Visakha Bucha Day.

During the holiday, the temples are decorated with colorful lanterns and flags, making it a magnificent night view. You could witness the locals visiting temples for goodwill, offering alms to monks, and taking part in candlelit processions.

Temples in the Old City, such as Wat Phra Singh, Wat Chedi Luang, and Wat Chiang Man conduct evening chanting sessions to pay honor to Buddha. You could make offerings of flowers, candles, and incense after the chanting.

Travel tips: the 2025 Visakha Bucha Day will be held on Sunday, May 11th. Visakha Bucha Day ceremonies traditionally begin in the evening as the sun sets. Therefore it is recommended to arrange your temple visit in the afternoon if you want to see the ceremony.

With temperatures cooler than in downtown areas, Doi Inthanon National Park offers a refreshing escape from the summer heat in May. As the rainy season approaches, the park presents a verdant tapestry , transforming the surroundings into a lush green paradise.

Meanwhile, the waterfalls within Doi Inthanon National Park, such as Wachirathan and Siriphum, also provide a refreshing retreat from the hot temperature.

Be aware that the fog after rainfall could obscure your visibility on the mountaintops. To avoid this, consider skipping early mornings or late afternoons with rain.
