Larger vessels heading north from Bergen navigate south of Ask\u00f8y into Hjeltefjorden, while other traffic utilizes the clear and deep Herdlefjorden, Det Nauar, and Skjeljangssundet.
The land along the southeastern part of Herdlefjorden is low and picturesque on the Ask\u00f8y side, featuring wooded terrain and relatively dense settlements. On Holsn\u00f8y, the landscape is more barren and forested with sparse settlements. Further northwest in the fjord, the landscape changes character. The Ask\u00f8y side becomes gray and monotonous, while Holsn\u00f8y sees richer vegetation.
The tidal stream flows inward (towards the southeast) with rising water and outward with falling water. The incoming current is most pronounced along the southern shore, while the outgoing current is most pronounced along the northern shore. The current is strongest through Herdlesundet and Det Nauar.
The tidal currents in Herdlefjorden flow inward towards Salhusfjorden and the fjords surrounding Oster\u00f8y with rising water and in the opposite direction with falling water.
The tidal amplitude and the timing of high and low tide are relatively uniform throughout the region. Exceptions are fjords with particularly narrow and shallow openings where the tide is delayed, and the tidal differences are smaller compared to the area outside (e.g., Straumsosen north in Lurefjorden).
All outer ports in the fjords of Nordhordland are ice-free. However, ice often forms at the heads of the fjords and in enclosed bays but seldom poses a hindrance to navigation.
", "description_no":"St\u00f8rre fart\u00f8yer som skal N\u2011over fra Bergen, g\u00e5r S om Ask\u00f8y ut i Hjeltefjorden, mens den \u00f8vrige trafik en bruker den rene og dype Herdlefjorden, Det Nauar og Skjeljangssundet.
Landet langs s\u00f8r\u00f8stre delen av Herdlefjorden er p\u00e5 Ask\u00f8y\u2011siden lavt, vakkert, skogkledd terreng med til dels tett bebyggelse. P\u00e5 Holsn\u00f8y er derimot landskapet mer goldt og skogbart med lite bebyggelse. Lengre NW i fjorden skifter landskapet karakter. Ask\u00f8y\u2011siden blir gr\u00e5 og ensformig, mens Holsn\u00f8y f\u00e5r en frodigere vegetasjon.
Tidevannsstr\u00f8mmen g\u00e5r innover (mot SE) p\u00e5 stigende vann og utover p\u00e5 fallende vann. Inng\u00e5ende str\u00f8m er mest markert langs s\u00f8ndre land mens utg\u00e5ende str\u00f8m er mest markert langs nordre land. Str\u00f8mmen er sterkest gjennom Herdlesundet og Det Nauar.
Tidevannsstr\u00f8mmene i Herdlefjorden g\u00e5r p\u00e5 stigende vann innover mot Salhusfjorden og fjordene rundt Oster\u00f8y, og motsatt retning p\u00e5 fallenede vann.
Tidevannsamplituden og tidspunktene for h\u00f8y- og lavvann er relativt like i hele regionen. Unntaket er fjorder med spesielt trang og grunn \u00e5pning der tidevannet er forsinket og tidevannsforskjellene er mindre i forhold til omr\u00e5det utenfor (eks. Straumsosen N i Lurefjorden).
Alle de ytre havnene i fjordene i Nordhordland er isfrie. Isen legger seg imidlertid ofte i fjordbunnene og i innelukkede v\u00e5ger, men blir sjelden til hinder for seilasen.
