Chiang Mai in March – Hazy Skies & Rising Heat 😷

March in Chiang Mai marks the beginning of the hot season, but the real challenge isn’t just the heat—it’s the burning season. Farmers burn agricultural waste, creating thick haze that affects air quality, sometimes reaching hazardous levels. It’s still possible to visit, but you’ll need to be prepared for smoky skies and reduced visibility.

☀️ Weather at a Glance

• 🌡️ Temperature: 20-37°C (68-99°F) – Hot days, warm nights
• 💨 Air Quality: Poor to hazardous due to crop burning
• 🌧️ Rain: Almost none (dry and dusty)

🌴 What’s Good About March?

• ✔️ Lower prices as high season ends
• ✔️ Fewer tourists than peak winter months
• ✔️ Warm evenings are still great for night markets & outdoor dining
• ✔️ Temples and attractions are less crowded

🚨 What to Watch Out For…

• ❌ Severe haze & pollution – Chiang Mai often ranks among the most polluted cities in March
• ❌ Outdoor activities suffer – Mountain views, waterfalls, and hikes lose their charm under thick smoke
• ❌ Hot & dry – Afternoons can be uncomfortable, especially late March

💨 How Bad Is the Burning Season?

March is one of the worst months for air pollution in Chiang Mai, with AQI levels often exceeding 200-300+ (unhealthy to hazardous). Locals and expats frequently leave the city for cleaner air, heading to the southern islands or international destinations.

If you have respiratory issues, it’s best to avoid Chiang Mai in March.

🛎️ Pro Tips for Visiting in March

• Book a hotel with air purifiers – Many accommodations in Chiang Mai now offer rooms with air filtration.
• Check AQI levels daily – Websites like IQAir and apps like AirVisual help monitor pollution.
• Plan indoor activities – Chiang Mai has great cafés, coworking spaces, spas, and malls for escaping the haze.
• Wear an N95 mask if you’re out for long periods.

🌍 Is March a Good Time to Visit Chiang Mai?

Honestly, no. The heat is manageable, but the burning season makes March one of the least desirable months to visit. If you’re set on coming, aim for early March before pollution peaks, but be ready for smoky skies and limited outdoor options. For a better experience, consider visiting from November to February instead.

🚀 Better Alternative? Head south to Krabi, Koh Lanta, or Koh Phangan, where the air is fresh, and the beaches are stunning.

Chiang Mai in April – Scorching Hot but Culturally Rich 🔥

April in Chiang Mai is HOT, like really hot! I spent last April sweating through Songkran festival, and while the temperature was brutal, the water fights were the perfect antidote. This is when northern Thailand shows its extreme side – prepare for heat but also some of the most vibrant cultural experiences of the year.

☀️ Weather at a Glance

🌴 What’s Great in April?

• ✔️ Songkran Festival (Thai New Year) – the world’s biggest water fight offers welcome relief from the heat
• ✔️ Smaller crowds at temples and attractions (except during Songkran)
• ✔️ Lower accommodation rates outside the Songkran period (April 13-15)

🚨 But Here’s the Catch…

• ❌ Extremely hot temperatures make daytime exploration challenging
• ❌ Burning season may still affect air quality in early April
• ❌ Many locals leave the city during the hottest period

🌍 So, Is April a Good Time to Visit Chiang Mai?

If you can handle extreme heat and want to experience Songkran, April is worth it. Otherwise, consider postponing to November-February for more comfortable exploring weather.
