Vladivostok, Russia's principal Pacific port, sits on a peninsula on the Sea of Japan in the far southeast of the country, near the Chinese and Korean borders at approximately 43.12°N, 131.89°E. Its coastal position gives it a monsoon-influenced humid continental climate (Köppen Dwb) — with cold, dry, sunny winters and cool, damp, foggy summers.

Summer, from June to August, is cool and humid rather than hot, with August the warmest month — average highs around 23–24°C — as the East Asian summer monsoon brings warm, moist Pacific air onshore. It is by far the wettest season, with frequent fog and drizzle, and late summer can bring the remnants of Pacific typhoons with torrential rain.

Winter, from December to February, is cold, dry and often brilliantly sunny, with January the coldest month — average highs around -8°C and lows near -14°C — far colder than the latitude suggests, because the prevailing winter wind carries frigid Siberian air out to the coast. The harbour freezes and must be kept open by icebreakers.

Vladivostok receives around 800–840 mm of precipitation a year, overwhelmingly in the summer monsoon months from June to September, when fog and rain are frequent, while the winter is very dry with light snow. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Vladivostok's climate is a study in reversal: its winters are as cold as far-inland Siberia because the prevailing wind blows off the frozen continent, freezing the harbour solid; its summers are cool, grey and fog-bound as the monsoon carries damp Pacific air ashore — the opposite of what a coastal city at this latitude might expect.
