There's something about Chicago in January that reveals the city's true character. I visited during the polar vortex — minus 25°C, Lake Michigan frozen at the edges, and the locals still walked to their neighborhood taverns as if nothing was unusual. The cultural calendar thrives in winter: theaters full, restaurants cozy, museums uncrowded. Summer (June-August) is when Chicago reclaims its lakefront — 25°C, festivals every weekend, the energy electric. I love October: 14°C, the city in autumn colors, and a melancholy knowing winter is coming. Each season reveals a different Chicago.
