Goosebumps and shivers aren't usually symptoms associated with summer.
But if you've taken a dive into fresh New Zealand waters that's probably what you've come up with.
And it's not just your imagination, Niwa meteorologist Ben Noll confirmed that water temperatures are 1°C to 1.5°C cooler than average.
"So maybe you've been holidaying and you've ran into the water and its been really chilly so you sprint back out. So what's going on?"
Noll put the chilly oceans down to two reasons. One is an abnormal amount of south-westerly winds. This brought cooler air over the Tasman Sea and areas east of the country.
