Istanbul Weather & Live Wind, Snow & Storm Map
Is the Lodos about to whip up the Bosphorus — or is a cold snap bringing snow?
Istanbul is a city of in-betweens — straddling Europe and Asia across the Bosphorus, sitting between the Black Sea and the Mediterranean — and its weather reflects that crossroads. Influences arrive from several directions, giving the city more variety than its mild latitude would suggest: warm and stormy southwesterly winds, cold snaps that can bury it in surprise snow, and hot, dry summers. More than in most cities, the wind here is the key to the day, and reading it is exactly what the live map helps with.
The winds that rule the Bosphorus
Istanbul's weather is governed by two great winds, and locals know both by name. The Lodos is a warm, often powerful southwesterly. When it blows hard, it churns up the Bosphorus and the Sea of Marmara, and because the city's life depends on ferries crossing those waters, a strong Lodos can snarl transport, halt crossings and bring near-stormy conditions to the waterfront. It often arrives ahead of unsettled, wet weather.
Its counterpart is the Poyraz, a cold, dry northeasterly that sweeps in clearer, cooler air. The two winds essentially trade control of the city's weather, and knowing which is blowing tells you much of what to expect. That's why, in Istanbul, the wind layer is often the first thing worth checking.
Surprise snow
Istanbul's climate is broadly mild and Mediterranean, but it has a colder side that can catch the unprepared. In winter, cold air sweeping down from the north and east can deliver genuine cold snaps and, on occasion, heavy snowfall. Major snowstorms periodically blanket the city, disrupting travel, closing the airport and transforming the famous skyline into something out of a winter postcard. Snow isn't a certainty each year, but when a strong cold outbreak lines up with moisture, the city can change character overnight — a reminder that a Mediterranean city perched near colder air masses keeps winter as a live possibility.
Hot, dry summers
At the other end of the year, summers turn hot and largely dry. Heat builds across the region, and during a heatwave temperatures can climb to uncomfortable, even hazardous, levels — part of the broader pattern of intense Mediterranean and Middle Eastern summer heat. Between the hot summers and the cold-snap winters, with changeable, breezy springs and autumns in between, Istanbul offers a fuller range of weather than many expect of a city on the Mediterranean's doorstep.
Reading it on the live map
Istanbul rewards leading with the wind:
- Read the wind first. Turn on the Wind layer to see whether the warm Lodos or the cold Poyraz is in control — a strong Lodos is your warning for rough water on the Bosphorus and unsettled weather.
- Track the temperature. Use Temperature to follow summer heatwaves and the winter cold outbreaks that can bring snow.
- Watch for precipitation. Add Radar to see incoming rain or snow as a system approaches.
- Connect the threads. The wind-maps guide explains how to read flow like the Lodos and Poyraz, and the polar-vortex and heat-dome guides cover the cold and heat extremes that bracket the city's year.
Wind tells you which way the day is leaning, temperature tells you whether it's heat or cold to watch, and radar tells you when the weather arrives. In a city built across two continents and two seas, reading the wind first is how you stay ahead of Istanbul's changeable skies.
Frequently asked questions
What are the Lodos and Poyraz winds?
They're the two dominant winds that shape Istanbul's weather. The Lodos is a warm, often strong southwesterly that can blow hard enough to whip up the Bosphorus and the Sea of Marmara, disrupting the ferries that knit the city together and sometimes driving storm-like conditions. The Poyraz is its opposite — a cold, dry northeasterly that brings clearer, cooler air. Which one is blowing tells you a great deal about the day's weather, which is why wind is such a key layer here.
Does it snow in Istanbul?
Yes, and sometimes heavily. Although Istanbul has a mild, broadly Mediterranean climate, cold air sweeping down from the north and east in winter can bring genuine cold snaps and significant snowfall. Major snowstorms occasionally blanket the city, disrupting travel and closing the airport. Snow is far from guaranteed each winter, but when a strong cold outbreak arrives, the city can be transformed.
What is Istanbul's weather like across the year?
It spans a real range. Summers are hot and largely dry, with heat that can become intense during a heatwave. Winters are cool and wet, with the chance of snow during cold outbreaks. Spring and autumn are milder and changeable. Sitting where Europe meets Asia, between the Black Sea and the Mediterranean, the city sees influences from several directions, which gives its weather more variety than its latitude alone suggests.
How do I read Istanbul's weather on the map?
Turn on the Wind layer to see whether the Lodos or the Poyraz is in control — a strong Lodos is your cue for rough seas on the Bosphorus — Temperature to track summer heat and winter cold snaps, and Radar for incoming rain and snow. In a city defined by its winds and its position between seas, the wind layer is often the first thing to check.
