What does baltic mean?
Baltic is an adjective with two distinct uses. In its standard sense, it describes anything connected to the Baltic Sea and the region around it — most prominently the Baltic states of Estonia, Latvia, and Lithuania, as well as their peoples, languages (which belong to the Balto-Slavic branch of Indo-European), cultures, and economies. Used this way, it is neutral in tone and common in geography, history, politics, and travel writing. In Britain, however, baltic has also developed an informal slang meaning: extremely cold. Saying 'it's baltic outside' evokes the famously frigid northern sea, making the comparison both vivid and humorous. This colloquial use is widespread in everyday British speech but largely absent elsewhere. The word derives its name ultimately from the Baltic Sea itself, whose name has uncertain early origins but became established across European languages. Whether describing a geopolitical region or biting weather, baltic carries strong associations with northern Europe's cold climate.
Of or relating to the Baltic Sea, the Baltic states (Estonia, Latvia, and Lithuania), or the region and peoples surrounding them.
"The summit brought together leaders from across the Baltic region."
Usually used in reference to geography, politics, culture, or languages of north-eastern Europe.
(British informal) Extremely cold; freezing.
"Don't forget your gloves — it's baltic this morning."
Chiefly British slang, not typically used in formal writing.
In British slang, saying it's 'baltic' outside means it's so cold that a sea famous for freezing over sounds like the natural comparison.

Etymology of baltic
The adjective 'baltic' derives from the Baltic Sea, whose name first appeared in Latinized form (as 'Mare Balticum') in medieval sources around the eleventh century. The ultimate origin of the name 'Baltic' is uncertain, though one long-standing suggestion links it to the Latin 'balteus', meaning 'belt' or 'girdle', possibly describing the sea's shape. From the sea's name came broader uses referring to the surrounding region and, later, to the peoples and languages of the area. The British slang sense meaning 'extremely cold' arose more recently by association with the sea's notoriously freezing waters.
Usage notes
When capitalized as part of proper names (Baltic Sea, Baltic states), the word refers to specific geographic entities. The slang sense for extreme cold is chiefly British and informal.
