About EPWA Weather Station

Warsaw Chopin Airport (EPWA) serves as the primary weather observation station for Warsaw. Located about 10 kilometers southwest of the city center, the airport sits at 361 feet (110 meters) elevation on the Masovian Plain.

Poland's position between maritime Western Europe and continental Russia creates a transitional climate zone where competing air masses generate significant weather variability. Temperature observations follow IMGW (Polish meteorological service) standards.

Warsaw's continental location means temperature extremes exceed those of Western European cities at similar latitudes.

Climate Patterns

Warsaw has a humid continental climate (Koppen: Dfb) with cold winters and warm summers. The city experiences four distinct seasons with significant temperature differences between summer and winter.

Summer highs typically reach 24-26°C (75-79°F), occasionally exceeding 30°C during heat waves. Winters are cold with highs around 0-2°C (32-36°F) and extended periods of sub-freezing temperatures. The annual temperature range exceeds 45°C.

Precipitation is moderate and distributed throughout the year, with slightly more in summer months.

Seasonal Trading Considerations

Winter (December - February): Cold with highs around 0°C (32°F). Arctic outbreaks bring temperatures below -15°C. Snow common. Occasional mild Atlantic intrusions.

Spring (March - May): Rapid warming but variable. Late frost possible into April. Temperature swings of 15-20°C within a week common.

Summer (June - August): Warm with highs 24-28°C (75-82°F). Heat waves can bring 35°C+. Thunderstorms provide afternoon cooling.

Autumn (September - November): Gradual cooling with pleasant September. Increasing cloud and rain. First frosts in October.

Trading Tips for Warsaw

Warsaw sits in a battleground between Atlantic and Continental air masses. Track the position of the polar front and high pressure systems to anticipate temperature regimes.

Winter temperature variability is extreme - mild Atlantic air can bring highs near 10°C while Siberian cold can push temperatures below -20°C within a week.

Summer heat waves are associated with high pressure extending from southern Europe or the Azores. These can bring multi-day periods above 30°C.

IMGW (Polish meteorological service) provides excellent forecasts. The European model (ECMWF) is highly reliable for Poland.

The urban heat island of Warsaw proper means the airport may read slightly cooler than central city locations.
