If you're planning outdoor activities in Buenos Aires, the seasons are flipped but mild. I ran the Costanera Sur in January (summer): 30°C with 70% humidity, draining but the river breeze helped. March-April is the outdoor sweet spot: 22°C, manageable UV, empty paths. October-November is similarly ideal — jacarandas blooming, 20°C, perfect cycling weather. July (winter) brings 12°C and dampness; running is fine but mornings feel raw. UV peaks dangerously in January (11+); sun protection is mandatory between 10am-4pm. The wind off the Río de la Plata is constant and can be bracing in winter.
