Lifeguards Liam O'Leary and Christian Conder, both 19, said they are enjoying working their third season at the Aquatic Centre.
"It's a good summer job and I look forward to coming back each year," said Liam.
The trust overseeing the pool has been helped with a grant from the Whanganui Community Foundation which allows it to keep admission prices down and also provide some shade cloths.
Preschoolers and spectators get in for free, children are $2.50, adults $3.50, students and gold card holders $3. A swim and hydroslide pass costs $4 for children and $5 for adults.
Concession tickets are available, giving children 10 swims for $20 and adults 10 swims for $30.
Liam said admission fees were being kept to a minimum to attract as many people as they could.
The centre will be open every day during summer and hours are: Monday to Thursday, 10am to 6pm, Friday to Sunday, 10am to 5pm and public holidays, 12 noon to 5pm.
