The inlet is a drowned river valley running parallel to the west coast. It is some {{convert|13|km|mi}} in length and on average is about {{convert|2.5|km|mi}} wide. A narrow channel halfway along the valley connects the inlet to the [[Tasman Sea]].<ref>{{cite web| last=Freeman |first=Leonie |url= https://www.aa.co.nz/travel/editorial/westhaven-whanganui-inlet-marine-and-wildlife-reserve/ |title=Westhaven (Whanganui Inlet) marine and wildlife reserve |publisher=AA New Zealand |access-date=15 September 2018}}</ref> This channel is located {{convert|19|km|mi}} southwest of [[Farewell Spit]].<ref>{{cite web| last=Walrond |first=Carl |url= http://www.TeAra.govt.nz/en/photograph/29132/whanganui-inlet |title=Whanganui Inlet |website=[[Te Ara: The Encyclopedia of New Zealand]] |date=22 April 2015 |access-date=15 September 2018}}</ref>
It is still in a largely unspoilt natural state, with seagrass and salt marsh providing an environment friendly to sea life. It is a popular site for fishing and boating, and much of the inlet is protected by a wildlife management area and by the [[Westhaven Marine Reserve]].<ref>{{cite web| url= http://www.tasman.govt.nz/environment/coastal-marine/coastal-marine-biodiversity/estuarine-information/how-do-tasman-s-estuaries-measure-up/whanganui-inlet/ |title=Whanganui Inlet |publisher=[[Tasman District Council]] |archive-url= https://web.archive.org/web/20180914203705/http://www.tasman.govt.nz/environment/coastal-marine/coastal-marine-biodiversity/estuarine-information/how-do-tasman-s-estuaries-measure-up/whanganui-inlet/ |archive-date=14 September 2018}}</ref> 42 species of water bird have been seen in the Inlet, including [[South Island oystercatcher|South Island oyster catcher]], [[bar-tailed godwit]], [[Red knot|knot]], [[Double-banded plover|banded dotterel]] and [[Buff-banded rail|banded rail]].<ref name=":0">{{Cite web |date=1989 |title=Ecological investigation of Whanganui Inlet |url=https://www.doc.govt.nz/globalassets/documents/conservation/estuaries/the-ecology-of-whanganui-inlet.pdf |website=DoC}}</ref>
In 1846 it was reported that ships of up to 80 tons could cross the bar and that one had taken a cargo of coal away from outcrops on islands at the south end of the harbour.<ref>{{Cite web |date=5 September 1846 |title=NOTES of an EXPEDITION to Kawatiri and Araura, on the WESTERN COAST of the MIDDLE ISLAND, performed by Messrs.

In 1908 the town of Rakopi was established opposite the entrance, with a telegraph office, sawmill, wharf, school and houses. Declining resources, an economic downturn and the dangerous passage for ships through the entrance caused its decline.<ref name=":0" /> The Benara Timber Co and Westhaven Coal Co were still operating at the south end of the Inlet in 1941.<ref>{{Cite web |date=12 August 1941 |title=ROYALTY ON TIMBER AND COAL.
