Downtown in June

April through October offers the best weather for exploring on foot. Spring brings food festivals to the plaza areas, while summer means rooftop bar season kicks into high gear. But July and August can feel like walking through a furnace with all that concrete and glass reflecting heat. Fall might be peak downtown season. September through November delivers perfect walking weather, and the business calendar picks up after summer vacations. Hotel rates climb during major conference seasons, typically March, September, and October. Winter downtown has its own appeal if you don't mind bundling up. December brings holiday markets to the main squares, and January restaurant week offers prix fixe menus at places normally out of reach. Just know that those wind tunnels between buildings turn brutal when temperatures drop.
