Sanctuary‘s ratings are on the rebound since the conclusion of the big networks’ 2010-2011 broadcast season three weeks ago. After bouncing back 39 percent in its first episode of the summer season (story), the fantasy series starring Stargate‘s Amanda Tapping is up another big leap this week.

“Out of the Blue,” the penultimate episode of Season Three, drew 1.201 million viewers (Live + Same Day) and a 0.4 rating in the Adults 18-49 demo, according to TVBytheNumbers. That’s a gain of 31 percent and almost 300,000 viewers from the previous week, and the show’s highest rating for a Monday night episode yet.

But it’s still below the show’s Friday night average. Sanctuary‘s tough time during the spring broadcast season — and its big improvement after the Monday night competition went away — further proves our theory that Mondays (and Tuesdays) just aren’t friendly to Syfy Channel dramas during the network broadcast season.

Sanctuary concludes its third season this Monday at 10/9c on Syfy.
