History hasn't set an official release date for the second half of Vikings season 6 yet, but all the evidence points to a fall release. "The remaining 10 episodes of season 6 are slated to air in 2020," Deadline confirmed ahead of the sixth season's premiere in 2019. If the report still holds true and the network does indeed want to get all the remaining episodes out in 2020, it would have to start dishing them out by October at the latest, though history suggests that it will wait until the following month — the second parts of seasons 4 and 5 both premiered in November and ran over into the next year.

Vikings season 6 wrapped long before the COVID-19 pandemic shut down film and TV productions the world over ("We stopped shooting the final episode in November last year," Michael Hirst told Variety in 2019), so we don't expect there to be any coronavirus-related delays when it comes to the remaining episodes. To their credit, the cast has been actively engaging with fans during the virus crisis, urging them to stay home and stay safe. Floki actor Gustaf Skarsgård won praise from his Vikings co-stars when he shared a corona-themed poem on his Instagram, calling for calm in uncertain times. "I just hope we don't resort to chaos and calamity, now we're finally forced to face our own mortality," he said.
