Internet in Chiang Mai

In M-Lab's open speed tests within 25 km of Chiang Mai, half came in above 33 Mbps download and 21 Mbps upload, and the fastest quarter of lines above 91 Mbps.

That's 346,176 download tests from September 2025 to September 2026.

The typical figure counts every line, cheap and mobile ones too; a fiber line in a good apartment or coworking space is closer to the fastest quarter.

Cost of living in Chiang Mai

One person spends about $925 a month in Chiang Mai, with a furnished place to stay:

The rent is estimated from Thailand's housing prices, as Inside Airbnb doesn't cover Chiang Mai.

The rest is what a one-person US household spends (the Bureau of Labor Statistics' 2024 survey), at Thailand's prices for each (the World Bank's 2021 price comparison).

Coworking, insurance and flights come on top.

Air quality in Chiang Mai

The air in Chiang Mai carries about 32 µg/m³ of fine particles (PM2.5) over a year, 6.4 times the WHO's guideline of 5 µg/m³.

The cleanest month is August, at about 10 µg/m³, and the haziest is March.

In March it climbs to about 78 µg/m³, so plan around it if you're sensitive to smoke or haze.

From the 3 low-cost sensors nearest Chiang Mai, all within 2.6 km, through OpenAQ's open air quality data, each month's average since 2023: Chiang moi (AirGradient, CC BY 4.0, 1.1 km); Chiang Mai (AirGradient, CC BY 4.0, 1.6 km); Suthep (AirGradient, CC BY 4.0, 2.6 km).

Low-cost sensors read less precisely than government monitors, so take the figures as a guide.

Is Chiang Mai safe?

The US State Department rates Thailand Level 1 ("Exercise normal precautions", updated 2026-07-07), the same level it gives Austria, Portugal, Japan and Australia.

Level 1 is normal travel.

Some advisories raise the level for parts of a country, so read the full advisory before you book.

Work and stay in Chiang Mai

Visas, taxes and residency in Thailand

Before you plan a long stay, check what your passport allows and what staying does to your taxes:

• Can you stay? – see where your passport goes without a visa on the visa-free countries map, and whether Thailand has a visa for remote workers in the digital nomad visa finder
• Tax – compare Thailand's income tax with other countries in tax rates by country
• Foreign income – Thailand taxes foreign income only when you bring it into the country; see the rule and its exceptions on the territorial tax map

Each tool reads the official rules, so the answer is for your own passport and income.

Money in Chiang Mai

A card with no foreign fee and an account that holds several currencies make a stay much cheaper:

• Accounts – the best bank accounts for digital nomads, by where you live
• Cards – what a card costs you abroad in the card fees abroad calculator
• Sending money – the cheapest way to move money there in the money transfer comparison

The finders show only accounts and cards you can open from where you live.
