Yes there will be a 4th season of Whale Wars. The next campaign is Operation No Compromise and it begins December 2nd out of Hobart, Tasmania.
With ratings this season some of the highest ever (the season three finale was the highest rated regular telecast ever for Animal Planet among key Demographics), bringing back the crew of the Sea Shepherd and their fleet of anti-whaling vessels is definitely a no-brainer for the network. AP may also receive some celebrity star power in the form of actress Michelle Rodriguez; who has pledged to join the SS crew on this year's Antarctic campaign.
Based on previous seasons, you can expect Whale Wars Season Four to splash into your living room sometime around June 2011.
'Whale Wars' season premiere was on June 3, 2011. The show will then be continuing for 9weeks every Friday night on Animal Planet.
No one knows because Season 3 is still going on.
