Is September Right for You?
Weigh the advantages and considerations before booking
- + The Mekong River swells to its most dramatic level, brown water racing past Thailand's bank toward Laos, creating the photogenic border crossing locals call 'liquid gold hour' every evening around 6:15 PM
- + Guesthouse balconies along Rimkhong Road drop to shoulder-season rates 30-40% below December peaks. Yet the teak wood floors still creak the same and the river breeze through louvered windows hasn't changed
- + Morning fog over the river creates natural air-conditioning until 9 AM, good for cycling the 12 km (7.5 mile) riverside path to Ban Hat Bai without melting
- + September's storms wash the dust off Wat Sob Som's 700-year-old laterite bricks, making the temple's ochre walls photograph like they've been freshly painted
- − Mosquitoes breed in the paddy fields behind town, bring repellent or spend evenings slapping your ankles at riverside beer gardens
- − The Chiang Khong-Houay Xai ferry runs on 'rain time,' meaning departures stretch from every 30 minutes to whenever 20 passengers accumulate under the tin-roof shelter
- − Mountain roads to Phu Chi Fa viewpoint turn to red clay slip-n-slides, 4WD essential, and even locals won't attempt it after 3 PM storms
Best Activities in September
Top things to do during your visit
September's swollen river creates foreground drama for shots of Laos' distant hills. The golden light between storms at 5:30-6:30 PM reflects off muddy water like liquid bronze. Local boatmen know exactly where to position for shots of fisherman casting circular nets against the storm-lit sky.
The 25 km (15.5 mile) loop through Ban Pha Hiang's 40-year-old oolong terraces rides best in September's cooler mornings. Tea leaves grow fat and glossy from the rains, creating that deep jade color you see on Thai tea packaging. Local pickers start at 6 AM, wave and they'll let you taste leaves fresh off the bush.
September's rain drives vendors under the covered section of the morning market where Lao traders sell sai ua sausage and Vietnamese drip coffee side by side. The steam from khao soi stalls creates natural saunas in the cool morning, good for warming up after cycling down the misty river road.
Huay Kaew waterfall becomes a 40-meter (131 ft) wall of brown water two hours after storms. The 4 km (2.5 mile) trail from Ban Don turns muddy but manageable with proper footwear. September's flow creates natural pools that locals use for post-hike swimming, water stays warm despite the rain.
September's humidity helps the roasting process, beans absorb moisture from the air, creating smoother flavor profiles. The 50-year-old roaster at Rimkhong Coffee uses wood from old rubber trees, giving beans a smoky edge that tastes like September in northern Thailand.
September Events & Festivals
What's happening during your visit
Late September brings the last lychee harvest to nearby Ban Hat Krai. Trucks loaded with golf-ball sized fruit create traffic jams on Highway 1020. Local families set up roadside stalls where you eat unlimited lychee for the price of a few kilos to take home.
