Surf Life Saving New Zealand has issued a message to surfers, who might be attracted to the large swells that are being caused by Cyclone Oma.

WeatherWatch.co.nz says the forecast computer models are aligning to suggest Cyclone Oma won't directly hit New Zealand.

'Instead, may offer some help at creating an even larger low in the NZ area.”

It was announced on Monday, that due to the ongoing swell and challenging surf conditions, doubled with the hot weather that Tauranga has been experiencing, Surf Life Saving New Zealand's local Eastern Region team has opted to continue observational lifeguard patrols along the coastline due to the considerable number of after-hours rescues and callouts.

Due to the low pressure systems in the Pacific, the swells are a lot larger than normal and this means the risk for swimmers getting into difficulty has increased.

Eastern Region Lifesaving Manager Chase Cahalane says with the bigger surf one would hope that those attracted are knowledgeable and experienced.

'However, that's not always the case, and sometimes even the most experienced people get into trouble.

'Make sure you check the conditions before you go – ensure they are within your personal limitations.

'Surf near a patrolled location but not between the flags. Tauranga beaches are being patrolled during the week until the end of February with roving patrols. Standard flag patrols continue in the weekends at all club locations.

'Never swim or surf alone. Always surf with a mate and tell somebody else where you are going and when you expect to be back.”

If in doubt, stay out. Chase says most rescues carried out come from people underestimating the conditions and overestimating their ability.

'If you get caught in a rip remember the 3 R's of Rip Safety, Relax, Raise your hand, Ride the rip.

'If you see someone in trouble, call 111 and ask for police.”
