The water here is 3.1 °C warmer than the September average of 11.0 °C. Warmer-than-normal water pushes cool-water species deeper and brings warm-water species in earlier than the calendar suggests. The water is mixed to about 54.0 m, so surface temperature carries well down the water column.

Local regulations

Norway

Species	Bag limit	Min size	Open season
Atlantic CodHøstingsforskriften (FOR-2021-12-23-3910) kapittel 10 (minstemål); § 40a (torsk i Oslofjorden)	—	min 55 cm	May 1 – Dec 31; Jan 1 – Dec 31
MINIMUM SIZE IS ZONE-DEPENDENT: north of 62°N it is 44 cm outside 4 nautical miles from the baselines and 55 cm inside 4 nm; south of 62°N it is 40 cm. FishRadar shows the strictest of the three (55 cm) because we cannot resolve which zone you are in. OSLOFJORD: cod fishing is banned all year, including while diving, in the whole sea area inside the baseline from Telemark to the Swedish border; bottom-set gillnets are banned there too. SPAWNING AREAS: inside 14 defined spawning areas from Lindesnes along the Skagerrak coast, in the Oslofjord and to the Swedish border, ALL fishing is banned 1 January – 30 April (spearfishing excepted, being fully selective). No daily count limit is published for recreational cod. Verify the zone on the Fiskeridirektoratet map before fishing.
Atlantic SalmonForskrift om fiske etter anadrome laksefisk i sjøen; åpningsforskriften	—	—	—
FishRadar publishes NO season, size or bag figure for Norwegian salmon, because Fiskeridirektoratet does not set them: anadromous salmonids in the sea are managed by Miljødirektoratet, and the county Statsforvalter (and municipalities) set the local rules that actually bind you. In principle rod and handline fishing for salmon, sea trout and sea char in the sea is open all year, but area- and period-specific exceptions are common and rivers are closed at short notice. When the river season is closed you must stay at least 100 m from the river/sea boundary. From a boat, a maximum of two rods or handlines per boat and one lure per rod. River fishing additionally requires the national fishing fee plus the river card, and the river card states that river's quota. CHECK THE STATSFORVALTER FOR YOUR COUNTY BEFORE FISHING.

Licensing:

saltwater-recreational — residents No licence required for recreational sea fishing with rod and line. Handheld tackle only for tourists; minimum sizes and closed areas apply., non-residents No licence required for sea fishing with rod and line. Only tourists aged 12 or older fishing through a REGISTERED fishing camp may export fish: 15 kg of fish or fish products, usable twice per calendar year (reduced to 10 kg from 1 January 2027). Trophy fish may not be exported on top of the quota.
freshwater-recreational — residents Anadromous salmon, sea trout and sea char are managed by Miljødirektoratet, not Fiskeridirektoratet. A national fishing fee plus a local river card is required for river fishing; the county Statsforvalter and the municipality set local rules., non-residents Same as residents. Check the Statsforvalter for the county you intend to fish before travelling — rivers are closed and reopened at short notice.

FishRadar regulations are summaries for informational purposes only. Norwegian rules vary by fjord, river, and season, and several closures are drawn on maps rather than described in text. Always verify with Fiskeridirektoratet at fiskeridir.no before fishing.
