Best Air Pollution Apps for Traveling in Thailand

Consistently one of the most accurate and user friendly AQI apps for Thailand, AirVisual blends data from government stations and trusted sensors with forecast models to give you a clear picture of PM2.5 now and over the next few days. The map view is excellent for spotting hotspots around Bangkok, Chiang Mai, Chiang Rai, and border regions where crop burning can spike quickly. You can switch AQI scales, set custom alerts, add multiple favorite locations, and use widgets or an Apple Watch complication for at a glance checks. Historical charts help you spot daily clean air windows, handy for morning runs or temple visits. If you own an IQAir indoor monitor, the app can display indoor versus outdoor readings to guide purifier use.

Air4Thai is the official Thai government app, pulling live data from the Pollution Control Department’s nationwide network. If you want the authoritative station reading for a specific province or district, this is your baseline. The interface is simple, with station lists, maps, and trend graphs, and it uses the Thai AQI scale that local agencies and media reference. Updates can occasionally be delayed during maintenance and the design is utilitarian, but the credibility of PCD data makes Air4Thai essential for cross checking other apps. For travelers moving between cities, it is useful to favorite key areas like Bangkok, Chiang Mai, Khon Kaen, and Phuket to compare conditions at a glance.

AirCare aggregates readings from official stations, community sensors, and satellite supported models to deliver a clean, modern view of air quality across Thailand. The home screen shows city tiles with color coded AQI, while a detailed map helps you zoom into neighborhoods in Bangkok or around Chiang Mai’s moat. You can set alerts, browse historical charts, and toggle between AQI standards. During burning season, the health recommendations, including mask hints and outdoor activity guidance, are practical and easy to follow. Forecasts help you pick cleaner hours for workouts or day trips, and the app’s design makes it friendly for first time users who want clarity without complexity.

Not a traditional AQI app, but a powerful companion for Thailand’s smoke season. Windy visualizes weather and air composition with beautiful, fast maps. Turn on the PM2.5 layer to see fine particle concentrations, then add wind to understand where smoke will move next. Layers for fires and satellite imagery help you spot hotspots in northern Thailand, Laos, and Myanmar, which often influence Chiang Mai and Chiang Rai. This context is invaluable if you are planning mountain hikes, photo trips, or long motorbike loops. While Windy does not send AQI push alerts, its forecast maps often explain why a city’s readings will improve or deteriorate over the next 24–72 hours.

AccuWeather integrates detailed air quality into a familiar weather app, useful if you prefer one place for both forecasts and AQI. The air quality page shows current PM2.5, hourly and daily forecasts, and health insights like suggested precautions for sensitive groups. Thanks to Plume Labs data and modeling, it performs well across major Thai cities, including Bangkok, Chiang Mai, and Phuket. You can set notifications, check real feel metrics, and align outdoor plans with expected cleaner windows. While it is not as granular as some dedicated AQI apps, the convenience of having weather, rain radar, and AQI in one app makes it a solid everyday choice for travelers.

A long time favorite among iOS users, Air Matters offers crisp visuals, reliable station selection, and helpful health guidance. It automatically picks the nearest quality station, shows clear trend charts, and lets you choose between AQI standards. If you use compatible purifiers from brands like Blueair, Philips, or Xiaomi, the app can display indoor readings and filter status alongside outdoor PM2.5, which is great for expats or long stay visitors who travel with portable purifiers. Notifications are straightforward to configure, and the Apple Watch app makes quick checks easy. The interface is minimal yet informative, ideal if you want actionable info without clutter.
