How many beaches are there in the world?

Every credible number, and what it actually counts

The reason the internet can’t agree on a number is that each authority is measuring something different.

World Beach Tour’s 228,612 sits exactly where a real count should: lower than raw OpenStreetMap (because we merge the segments that map one beach as many) and higher than any single register (because we combine all of them). It is the only published figure that reconciles the others.

Why there is no single answer

What even counts as a beach?

There is no agreed definition. A geomorphologist calls a beach a wave-deposited accumulation of loose sediment — but that sediment can be sand, shingle, pebble, cobble or shell. OpenStreetMap’s natural=beach tag includes shingle and pebble shores; most people picturing golden sand do not. Then there is named versus unnamed: gazetteers and certification programmes only capture named, notable, or managedbeaches, missing the vast majority of the world’s unnamed coves and strands. And “beach” isn’t only marine — lake, reservoir and river beaches qualify under most definitions, which is why the US count is dominated by the Great Lakes.

Where does one beach end and the next begin?

This is the coastline paradox applied to beaches. A single continuous arc of sand can be recorded as one beach or split into dozens of segments at every headland, river mouth or town boundary. That is exactly why OpenStreetMap lists 246,801 features [2] while the number of distinctbeaches is lower. Even the “longest beach” title is unstable: Praia do Cassino in Brazil is cited anywhere from 212 to 254 km depending on measurement resolution.[7]

Beaches move

Beaches appear and disappear with tides, storms and sediment supply. The 2018 satellite study of the world’s shorelines found that about a quarter of sandy beaches are actively eroding and another quarter are growing.[6] The coastline is literally moving, so any honest answer is a range anchored to a definition, not a single decimal number.

Five ways to count, five different answers

From the narrowest, strictest definition to the broadest — each is a legitimate answer to a slightly different question.

1. 4,323
   Certified beaches

   Beaches a programme like Blue Flag has vetted for water quality and safety. The strictest, smallest answer.
2. ~28,000
   Officially designated & monitored

   Government-registered bathing beaches — 21,848 in the EU plus 6,000+ monitored in the US. Still only wealthy, regulated coastlines.
3. tens of thousands
   Named beaches

   Beaches with a toponym recorded in gazetteers like GeoNames and Wikidata — notable enough to have earned a name.
4. 228,612
   All mapped & de-duplicated

   Every beach we can identify across six sources, merged so each is counted once. World Beach Tour's number — the most comprehensive count assembled.
5. uncountable
   Every physical beach on Earth

   31% of the world's shoreline is sandy, constantly shifting. At this definition the true number is effectively infinite.

How we counted 228,612

The World Beach Database is built by merging six independent sources — OpenStreetMap and Overture Maps, the EU bathing-water register, the US EPA’s BEACON system, Wikidata, GeoNames and Blue Flag. The same beach usually appears in several of them, and a single beach is often mapped as many fragments. So every record is run through a de-duplication step that merges entries within 500 metres of each other when their names match closely, collapsing the duplicates and segments into one beach.

What survives is 228,612 unique beaches across 249countries, each then enriched with climate, tide, protected-area and sand-mineralogy data. We don’t claim this is every beach on Earth — no honest source can. We claim it is the most comprehensive count anyone has assembled, and the only one that reconciles the numbers above.[1] You can browse the beaches or explore them by country.
