Wanganui Surf Lifesaving will reduce its beach patrols to weekends only after Waitangi Day.
Melanie Miller, spokesperson for Wanganui Surf Lifesaving, said with children returning to school weekday patrols would finish at the end of this week.
Mrs Miller said weekend patrols were likely to continue until the end ofFebruary.
"It really depends on the weather. If the weather breaks early, then they will finish early - there's little point in having guards there when there aren't many people on the beach."
Wanganui Surf Lifesaving guards patrol Castlecliff and Mowhanau beaches over the summer months.
