Climate	Temperate climate with hot summers and mild winters. Spring (September-November) and autumn (March-May) are the ideal seasons: 18-24 degrees C, low humidity, and the parks of Palermo in full bloom or turning gold. Summer (December-February) is hot and humid (32-38 degrees C) but Argentina's summer means the country is on holiday - the energy is high. January is when Porteños (Buenos Aires residents) leave for the coast; the city is quieter and restaurants offer summer discounts. Winter (June-August) is mild (8-15 degrees C) - the tango season peaks, the theatres fill, and the opera at the Colon is in full swing. The city has a remarkable cultural calendar year-round.	Tropical climate with two seasons: hot and wet (October-April) and warm and dry (May-September). The dry season (May-September) is the best time to visit: 25-28 degrees C, low humidity, and the city at its most pleasant. The Carnival (February or early March, dates change yearly) is the greatest street party on earth - 6 days of samba, blocos (street parties), and the Sambodromo parade. Book accommodation 6-12 months ahead for Carnival week and expect prices to triple. January-February is peak heat (35-40 degrees C) and rainy. The Christmas/New Year period brings the Reveillon beach celebration on Copacabana (2 million people in white, fireworks at midnight from the sea).
