Breanna Stewart enjoyed a red-hot August.

She doesn’t intend to cool down in September, especially with the New York Liberty beginning the postseason quest for their first-ever WNBA championship later this month.

That likely spells doom for her former Seattle teammates, who will be at Downtown’s Barclays Center Thursday night for the finale of a home-and-home series.

The reigning WNBA Most Valuable Player averaged 23.8 points in eight games last month after the league-best Liberty (27-6) returned to action following the Olympic break.

Stewart led New York in scoring in all but one of those contests and is coming off back-to-back 32-point performances, the last of which came at the expense of the Storm (20-13) last Friday night.

The three-time gold medalist as a member of Team USA, and two-time Finals MVP during her six-year tenure in Seattle has made a habit of lighting up her ex-teammates since signing here in 2023.

In six matchups since leaving the Emerald City, Stewart is putting up 23.3 points per game, the highest scoring average of any opposing player in Storm history.

The Liberty have won all six of those contests, including last weekend’s 98-85 triumph when Stewart became the first New York player ever to record consecutive 30-point efforts.

She reminded the sellout crowd of 15,800 at Climate Pledge Arena what they have been missing by draining 10-of-16 shots, including 3-of-4 from 3-point range while pulling down five rebounds and handing out six assists in a team-high 35 minutes.

“I mean, she had a complete game tonight,” Liberty coach Sandy Brondello gushed of Stewart.

After spearheading Seattle to championships in 2018 and 2020, as well as winning her first league MVP with the Storm in that first title year, Stewart came here to lift New York to the same heights.

Though they lost in four tough games to reigning back-to-back champion Las Vegas in Stewart’s first year, the Liberty are on top of the WNBA standings and ready to make another run at Title I later this month.

As for Seattle, it will always be Stewart’s first professional home.

“I think that I was saying on the TV broadcast, (it’s) sad that we only play one game here this season,” said Stewart, who had 16 points and 11 rebounds in the Liberty’s 74-63 triumph over the Storm here in Brooklyn on May 20.

“Seattle always has a special place in my heart.”

The Storm have other plans.

Not only are they eager to end their winless skid against Stewart, they also need to pick up some ground in the postseason race.

Seattle enters Barclays one game behind the dynastic Aces for the No. 4 seed and home-court advantage in the opening round of the playoffs.

The Storm did themselves and the Liberty a favor on Tuesday, beating second-place Connecticut 71-64 behind 18 points from Skylar Diggins-Smith.

It also ended a two-game slide for Seattle, which is 3-5 since the Olympics.

The victory over Connecticut (24-9) helped New York move three games ahead of the Sun and Minnesota (24-9) in the hunt for the top overall seed.

Diggins-Smith had 26 points in last Friday’s loss to the Liberty but only two in the fourth quarter, when New York outscored Seattle 24-14.

Stewart, who had 22 first-half points in that encounter, also helped the Liberty finish off a game-changing 11-0 run spanning the third and fourth quarters.

She made a layup and fed Courtney Vandersloot for a 24-footer that gave New York a 79-71 cushion early in the final period before adding two more baskets down the stretch to quell the crowd that used to adore her.

“I miss it here and appreciate the fans, whether they are for or against me,” Stewart said.

They’ll be for her in full throat on the corner of Atlantic and Flatbush for Thursday’s 7 p.m. tip-off.

GIVE ME LIBERTY:

• All-Star Liberty power forward Jonquel Jones needs five more assists to reach 500 for her career.
• Stewart has won the last 15 matchups between the Storm and Liberty, the first nine of those coming when she was wearing a Seattle uniform.
• After finishing their three-game season series with the Storm, the Liberty can do Seattle and favor when they host Las Vegas on Sunday at 4 p.m. That game will be televised by ESPN.
