The Australian is already 45 points behind standings-leading team-mate Sebastian Vettel after claiming only one podium finish in the opening four races of the season.
But Webber has won grands prix at five of the six circuits visited by F1 between now and the August break, with Montreal the only venue he has yet to triumph at.
"I have won at Monaco, won at Barcelona, won at Budapest, won at Silverstone, won at the Nurburgring so I have got some good form coming up," said Webber.
"I need to capitalise on that.
"It's quite timely and those races in the past have been OK for me.
"To get back in the championship [is possible]. It is still very, very early days but I'm looking to hit those middle steps [of the podium]."
Webber is hopeful that the Chinese and Bahrain Grands Prix, in which he retired and finished seventh respectively, will be his worst weekends of 2013.
"I'm looking to have Bahrain as the low point of my year, and China as well.
"Obviously China was a tough weekend that was going well until qualifying.
"In Bahrain, I damaged the car on the exit of Turn 3 very early in the race, so that was our race compromised from there.
"It is a sensational opportunity start from now.
"It's not a regroup, those races have gone and there have been missed points, but I still got a few on the board."
Spain, Monaco, Canada, Britain, Germany and Hungary host the next six races and, excluding Montreal, where he has never won, Webber has enjoyed the lion's share of his grand prix success on five of those tracks.
Seven of his nine victories have come at Barcelona, Monaco, Silverstone, the Nurburgring and the Hungaroring, as well as seven out of 11 pole positions.
Interlagos, which hosts the season-ending Brazilian Grand Prix, is his other form track, with two wins on his CV.
He also has pole positions in Malaysia, Turkey, Belgium and Korea.
