Plenty of participation in the Polar Plunge at Castlecliff Beach in Whanganui

Screams were heard amongst an icy blowing breeze as Whanganui locals of all ages made contact with the incoming tides of water at Castlecliff Beach.

Screaming was just one reaction to the clash between wintery water and cold skin, others ran back to shore to grab towels and some stood still, teeth chattering uncontrollably.

It was the More FM Polar Plunge 2018 and dress up costumes were made of wigs, capes, hats, masks and even butterfly wings.

Friends Erica Tanner, Abby Hurley and Jadzia Morris put in an impressive effort, taking the plunge despite attending Ohakune Mardi Gras the night before.

"We went to Mardi Gras as rainbows so we used these leftover balloons for the plunge, they were great flotation devices," Tanner said.

"It wasn't too cold actually, it was warmer than last year."

Tanner was taking part for the second time, while it was three for Morris and four for veteran plunger Tanner, who also attended one in Dunedin recently.

"We've dressed as bumblebees, brides and now balloons, hey they all start with b," said Morris.

"Is that because it's brrr cold?" Tanner replied, eliciting laughs all around.

Following the plunge, participants were looking forward to spot prizes being awarded, a sausage sizzle and certificate giving ceremony at Castlecliff Club Inc.
