The British crime thriller Under Salt Marsh has gained popularity since its release. Episode 3 is scheduled to release on Friday, 6 February 2026.

The six-part series aired on Sky Atlantic on 30 January 2026 and draws viewers into the fictional Welsh coastal town of Morfa Halen, which displays both violent and deadly emotions through the murder that shocked the community.

The series combines two elements, which include an exciting crime investigation and a deep character study of its protagonists. The viewers are intrigued by the dual narrative, which leads them to seek new information about the investigation while the town struggles to maintain its hidden truths and face its natural challenges.

The main characters of Under Salt Marsh show their connection as Kelly Reilly plays a former detective and teacher who has an ex-boyfriend played by Rafe Spall. The cast ensemble, Jonathon Pryce, Naomi Yang, Dinita Gohil, Brian Gleeson, and Harry Lawtey, is provided with their depth and authenticity to the town dwellers, and each of them adds to the suspense.

The show uses its design to establish an atmosphere of tension while the storm and coastal environment create both actual and symbolic hazards. The audience gets drawn into the story through this style, while it shows the personal and group conflicts that drive the movie forward.

Though there is no official schedule of episodes for Sky Atlantic, after the first episode, the series has maintained a routine of every Friday. Following this trend, one can assume that the next episode will be aired on Friday, 6th February 2026, most probably at the time of 9 pm UK time.

The deduced date matches what Sky has to do on its watch page, as all the other series will follow the same routine of releasing their series every Friday. Although the actual date of airing has not been established in a different official press release, the weekly schedule would be a reasonable method of determining when the third episode is going to be made available.

The evening shows of Sky Atlantic are generally replaced by on-demand viewing through NOW, the streaming service of Sky. This makes sure that subscribers can view episodes almost immediately after the premiere, giving them flexibility to those who cannot view live.

What took place in the last episodes

The first two episodes of Under Salt Marsh established the central conflict while creating the series's dark and suspenseful atmosphere. The plot unfolds in the imaginary town of Morfa Halen, which becomes the backdrop for a terrible crime that forces Kelly Reilly to return home as a teacher who used to work as a detective.

Her ex-boyfriend, who became her current estranged husband (Rafe Spall), joins the story about their complicated relationship, which creates both tension and emotional appeal during the investigation.

The first episodes establish the show through two major elements, which include its stormy coastal scenery and its rising ocean tides. The natural elements create an atmosphere of impending danger, which reveals the internal battles and community challenges that the characters encounter.

The initial episodes of the show present character development and character interactions to establish the series' world instead of revealing all its plot developments.

The supporting ensemble cast, which includes Jonathan Pryce, Naomi Yang, Dinita Gohil, Brian Gleeson, and Harry Lawtey, creates the town's social networks and hidden secrets and personal conflicts that drive the story forward. The viewers obtain an opportunity to experience the investigation and the emotional experiences of the characters through the detailed presentation of the story.


What to expect from Episode 3

Episode 3 has yet to be given any official synopsis by Sky. Judging by the tone, structure, and pacing found in the first two episodes, it is safe to expect that in the third episode (Episode 3):

Maintain the main investigation: The crime presented in the previous episodes will be the narrative center of attention, and the investigation will probably be more in-depth and vigorous.

Build character dynamics: It is anticipated that tension will be present between the teacher/former detective and her estranged ex-partner, not to mention these characters and the supporting cast.

Preserve the atmosphere of tension: Storm and coastal environment will also be a significant narrative and thematic background, which will add to suspense and stakes.

Stick to slow-burn storytelling: The series has taken a steady rhythm and has disclosed main plot points bit by bit to keep the viewers on their toes and the tension high.

These assumptions coincide with a set of the established tone of Under Salt Marsh, yet the specifics of the events and developments in the events of the third episode are interpretative speculations rather than definite plot elements.
