Sofia Guide for Digital Nomads

Weather in Sofia by month

The warmest month is August, at about 84°F (29°C) in the afternoon, and the coolest is January, at about 39°F (4°C).

The most rain falls in June.

From NOAA's monthly station summaries for Sofia, Bu (6.7 km away), averaged over 2011 to 2025.

Internet in Sofia

In M-Lab's open speed tests within 25 km of Sofia, half came in above 50 Mbps download and 14 Mbps upload, and the fastest quarter of lines above 129 Mbps.

That's 548,209 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 Sofia

One person spends about $1,329 a month in Sofia, with a furnished place to stay:

The rent is estimated from Bulgaria's housing prices, as Inside Airbnb doesn't cover Sofia.

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

Coworking, insurance and flights come on top.

Air quality in Sofia

The air in Sofia carries about 12 µg/m³ of fine particles (PM2.5) over a year, 2.3 times the WHO's guideline of 5 µg/m³.

The cleanest month is May, at about 7 µg/m³, and the haziest is January.

From the 2 government monitors nearest Sofia, within 9.4 km, through OpenAQ's open air quality data, each month's average since 2023: AMS Hipodruma-Sofia (EEA, ODC-BY, 2.9 km); AMS Kopitoto (EEA, ODC-BY, 9.4 km).

Is Sofia safe?

The US State Department rates Bulgaria Level 1 ("Exercise normal precautions", updated 2025-10-09), 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 Bulgaria

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 Bulgaria has a visa for remote workers in the digital nomad visa finder
• The Schengen area – Bulgaria is in it, so days here count toward your 90 in any 180; count them with the Schengen calculator
• Tax – compare Bulgaria's income tax with other countries in tax rates by country
• Foreign income – Bulgaria taxes its tax residents on their income from anywhere; 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 Sofia

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

Sofia runs on Sofia time (Europe/Sofia).
