It is not the start of a bad joke, but the reality of the St Clair Beach Polar Plunge in Dunedin yesterday.
More than 100 people braved the waters yesterday for the 93rd annual Polar Plunge, run by the St Clair Surf Life Saving Club.
St Clair Surf Life Saving Club chairman Cam Burrow said the water was "a bit chilly" at only about 10degC.
The plunge was all about getting people out to the beach and having a good time, regardless of the weather.
Those who braved the cold were treated to a blast of hot water from a fire hose, he said.
Polar Plunge participant Veronica Rodriguez entered the water three times.
She said jumping into the cold water filled her with adrenaline.
Frances Perry said the plunge felt great, but she could not wait to get home for a hot shower and a mug of mulled wine.
