When to fish atlantic cod in Maine

• Spring 20–100 ft — Work jigs or bait close to charted rock and ledges near the bay mouth; verify the current season and possession rules before targeting cod.
• Summer 45–180 ft — Warmer water pushes most cod deeper or offshore; inner-harbor spots should be read as low-confidence unless cold water and bait are present.
• Fall 25–140 ft — Probe the up-current face of ledges and charted rock with controlled bottom contact, and release prohibited or undersized fish promptly.
• Winter 50–220 ft — Most fishing is in deep offshore water and regulations can close or sharply limit harvest; the in-bay map is not an offshore forecast.
