Tips For Traveling To Chiang Mai in September

What To Wear

Same with July and August, September is a rainy month, and you should focus your packing list on the rain gears to fit with the weather.

We suggest:

• Pack breathable, quick-drying fabrics like nylon or moisture-wicking synthetics. They'll dry fast after you dash through a sudden shower.
• Opt for lightweight, breathable cotton or linen shirts and pants. Layering allows you to adjust to the humidity and occasional cooler evenings.
• A lightweight, packable raincoat is a must-have. Choose one that folds up easily and can be stashed in your daypack when not in use.
• Don't underestimate the power of a sturdy umbrella! Choose one that can withstand strong winds and rain, and consider a quick-drying canopy so you won't be left with a soggy mess.
• Pack comfortable, closed-toe shoes with good tread. Sandals might not be the best option due to slippery surfaces and the potential for mosquitos after rain.
• Pack a hat with a brim to shield yourself from the sun during breaks in the rain.
• Consider convertible pants that zip off into shorts, giving you more flexibility depending on the weather.
• A microfiber towel dries quickly and is perfect for wiping off after a downpour.

Book Your Accommodation Strategically

September, like all other months of the rainy season in Chiang Mai, is challenging for travel, but it offers us a big advantage to score some really good deals.

Let us give you some suggestions for being strategic when it comes to booking accommodation in Chiang Mai in September

• Make The Most Of  Your Money: Flights and accommodation hit rock bottom during the rainy season. Score a luxurious room at a fraction of the usual cost and free up some cash for delicious meals or unique experiences.

• Cancellation Policies: Weather can be unpredictable. Choose hotels with flexible cancellation policies if your plans change due to heavy rain. You might want to book activities closer to your arrival date for a clearer picture of the weather. ‍
• Embrace The Lushy  Vibe: Consider unique options like charming guesthouses with courtyards or boutique hotels with rooftop terraces. These can offer a more intimate and local experience, perfect for enjoying the city's vibrant atmosphere during breaks in the rain.
