Busan Guide for Digital Nomads

Weather in Busan by month

The warmest month is August, at about 86°F (30°C) in the afternoon, and the coolest is January, at about 46°F (8°C).

The most rain falls in July.

From NOAA's monthly station summaries for Busan, Ks (0.3 km away), averaged over 2011 to 2025.

Internet in Busan

In M-Lab's open speed tests within 25 km of Busan, half came in above 94 Mbps download and 90 Mbps upload, and the fastest quarter of lines above 319 Mbps.

That's 291,109 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 Busan

One person spends about $2,286 a month in Busan, with a furnished place to stay:

The rent is estimated from South Korea's housing prices, as Inside Airbnb doesn't cover Busan.

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

Coworking, insurance and flights come on top.

Air quality in Busan

By an estimate, the air in Busan carries about 41 µg/m³ of fine particles (PM2.5) over a year, 8.2 times the WHO's guideline of 5 µg/m³.

The cleanest month is August, at about 34 µg/m³, and the haziest is March.

No open air quality station is within 25 km of Busan, so these are estimates from Copernicus's CAMS air model for the surrounding area (an 80 km grid, 2023 to 2025, CC BY 4.0), adjusted to what stations measure elsewhere.

Take them as a guide: the model can be well off in big cities, and a measured figure replaces it once a station opens.

Is Busan safe?

The US State Department rates South Korea Level 1 ("Exercise normal precautions", updated 2025-05-28), 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.

Visas, taxes and residency in South Korea

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 South Korea has a visa for remote workers in the digital nomad visa finder
• Tax – compare South Korea's income tax with other countries in tax rates by country
• Foreign income – South Korea 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 Busan

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.

Time zone

Busan runs on Seoul time (Asia/Seoul).
