Six days after succumbing tamely to West Ham, the Magpies were largely outplayed by Swansea before slipping to a 2-1 defeat which left them in the bottom half of the table, a far cry from last season's high-flying heroics.
With striker Papiss Cisse missing because of a wrangle with the Senegal Football Federation, Fabricio Coloccini suspended and Jonas Gutierrez and Yohan Cabaye injured, Newcastle were once again woefully short of inspiration as they failed to break down the well-organised victors until the death.
A philosophical Pardew said: "You have to understand that in a managerial career at any football club, you are going to have some times when things don't go for you.
"Now we have had a week where it really has conspired against us in a lot of ways.
"Jonas was so close. We were deciding on whether to play him yesterday [Friday] and we felt with the injury he had, it was too risky, so he was very, very close.
"Then we had Papiss taken away from us, we had Shola [Ameobi] only arriving yesterday [Friday] afternoon [from international duty with Nigeria], so we had a lot of things that didn't work for us this week."
Newcastle were undone by two second-half strikes, but they could have few complaints about the result as the visitors more than made a game of it.
Michu's well-placed 58th-minute header - his eighth goal of the season - from Pablo Hernandez's cross set the ball rolling, and they secured the points with three minutes remaining when keeper Tim Krul could only parry substitute Danny Graham's shot and Jonathan de Guzman rifled the rebound home from a tight angle.
Demba Ba, who had squandered a series of earlier opportunities, headed home from close range - also his eighth of the campaign - after substitute Sylvain Marveaux's shot had come back off the bar, but there was to be no late salvation.
Pardew said: "Of course it's a concern, you don't want to lose and home game and we have lost two on the trot.
"But when you have a difficult period like we are having, you need your senior players in and around you and we haven't got them."
Cisse's absence was particularly galling with the Magpies issuing a withering attack on both the Senegal federation and FIFA after it became apparent that Cisse would not play.
Pardew said: "We kept getting promised that the decision was going to be overturned and that Senegal were going to let Papiss play, but we kept waiting and waiting and it was at about 1.40pm that we finally found out that wasn't going to happen.
"It did affect our preparation. Him missing today [Saturday] was a blow to us. We didn't feel we did anything wrong and he should have played."
Swansea boss Michael Laudrup was understandably delighted by his team's performance, which saw them leapfrog their hosts into 10th place.
He said: "It was the best away performance this season, including QPR and Liverpool.
"To come here and play Newcastle at a moment when we knew Newcastle really needed a win because they think they belong much higher than they are now after a home loss to West Ham a week ago, we knew it would be really difficult for us.
"But we put on a great performance. We can always discuss what is a big goal chance, but without my Swansea glasses, I think I can say we created at least eight or nine quite big chances, and that's very difficult to do as an away team against a team like Newcastle's."
The Magpies will attempt to book their place in the knockout stage of the Europa League on Thursday night when Maritimo head for St James', but domestic matters are becoming a major concern amid a run of seven Barclays Premier League games and just one win.
