No rain is predicted until Tuesday or Wednesday at the earliest, Ferris said.
Whanganui is protected from the worst of the weather coming from the east, and no giant waves are expected.
"For the most part, you will be sheltered from those as well."
However, winds could get breezier and seas rougher on Monday, but without much swell.
It would still be wise to keep an eye on the weather this weekend, Ferris said.
That's what Whanganui District Council will be doing, emergency management officer Anthony Edwards said.
The council has received the same "good public information" from MetService and isn't expecting problems here.
"[The cyclone] looks like it's tracking more east, which is good for us and for the East Coast also," Edwards said.
