Buffalo, New York has a humid continental climate with cold, snowy winters and warm, humid summers. The live forecast above shows current conditions, while lake-effect snow from Lake Erie frequently impacts the region from November through March.
What makes Buffalo’s weather unique?
Lake Erie drives much of Buffalo’s weather. In winter, cold air passes over the warmer lake and picks up moisture, producing heavy lake-effect snow bands that can drop 5–8 centimetres per hour. A buffalo weather warning may be issued during these events. Summer brings humidity and thunderstorms. Buffalo’s annual snowfall averages about 240 centimetres, making it one of the snowier US cities outside mountain regions.
When is the best time to visit Buffalo?
Late spring (May to June) and early autumn (September to October) offer the most comfortable weather. Daytime highs range from 18°C to 25°C with lower humidity. July and August are warmest, with highs near 27°C and frequent lake breezes. For current conditions, check a buffalo weather radar or a buffalo weather hourly update before heading out.
How accurate are long-range forecasts for Buffalo?
A buffalo weather forecast 14 day can show general trends but becomes less reliable after 7 days. For trip planning, a buffalo weather 15 day forecast or a 30 day weather forecast buffalo ny offers a rough guide, not a precise prediction.
Does Buffalo get lake-effect snow every winter?
Yes, lake-effect snow occurs multiple times each winter when cold air crosses Lake Erie. The southeast suburbs near the lake often receive the heaviest accumulations, while downtown Buffalo gets less intense but still frequent snowfall.
Is Buffalo humid in summer?
Yes, humidity peaks in July and August, with dew points often in the high teens. This makes warm days feel stickier than the actual temperature. Thunderstorms are common in late afternoon, especially after a hot spell.
