Two humpback whales surface off Sydney's northern beaches at the beginning of whale watching season during a Manly Whale Watching tour on June 23, 2011 in Sydney, Australia. The first day of winter in New South Wales, June 1st, marks the start of the Humback and southern right whales migration from southern regions to the north to warmer waters. Whale watchers should expect to have plenty to see with the whale population increasing each year. The migration north continues through July and with the whales returning between September and November.
