Portland, Maine Coast fishing forecast today

Portland, Maine Coast fishing conditions overview

The current weather inputs produce a good weather-based Fishing Score. Moderate wind should add useful surface movement.

Best fishing time today: estimated windows

The first estimated window runs from 5:57 AM–8:12 AM, around sunrise at 6:42 AM. The second runs from 4:48 PM–7:03 PM, around sunset at 6:18 PM. Lower light can change visibility and fish positioning, but actual feeding periods vary by species, season and water conditions.

Portland, Maine Coast fishing: structure, seasons and local conditions

Casco Bay coastline with islands, ledges and tidal shoreline fishing. For fishing decisions, useful local reference areas include ledges and sharp depth changes, together with island points, saddles and nearby breaks. Those features are more informative than treating the whole forecast area as one uniform piece of water. Portland, Maine Coast is driven by moving coastal water, so tide stage and current direction can change a spot even when wind and sky conditions are nearly unchanged. Channels, points and protected edges should be read together with the local tide cycle.

Maine has a pronounced warm-up and cool-down cycle. Spring can pull activity toward warming shallows or current edges; midsummer often increases the value of depth, shade, current or cooler water; and fall cooling can broaden the usable zone again. Those shifts matter differently to Striped bass and Mackerel, so recent conditions are more useful than assuming the same pattern all season. For Portland, Maine Coast, the useful comparison is between the forecast and the actual tide/current setup around ledges and sharp depth changes; island points, saddles and nearby breaks; and bay edges and protected water, not the score by itself.

Common targets at Portland, Maine Coast include Striped bass, Mackerel, and Pollock. They do not use depth, current and cover in exactly the same way, so the Fishing Score remains a conditions index rather than a species-specific bite prediction. This page has a mapped NOAA coastal station, so tide predictions and supported observations can be added when the current NOAA product is available.

What to watch in today's conditions

Wind

Current wind is about 7 mph from E, with gusts near 14 mph. Compare exposed water with protected shorelines and inlets because the same wind can produce very different surface conditions.

Waves

The NWS marine grid currently reports calm conditions at the forecast point (0.0 ft). Local wave conditions can still differ between exposed and sheltered water.

Barometric pressure

Barometric pressure is about 30.37 inHg. Pressure is one part of the Fishing Score and is read together with wind, cloud cover and precipitation.

Moon phase and light

The moon is currently in the Last Quarter phase with approximately 44% illumination. Lunar illumination has a smaller weight than the main weather factors.

Target species

Always verify current state fishing regulations, seasons, bag limits, licensing requirements and location-specific closures before fishing.

How this forecast is calculated

The Fishing Score starts with National Weather Service weather data: pressure 28%, wind 24%, cloud cover 18%, precipitation probability 18% and lunar illumination 12%. Missing weather factors are never treated as zero; partial weather results are pulled toward a neutral 5/10 according to the missing weight. On eligible river pages, a separate conservative USGS flow check can only reduce the current score when streamflow is unusually far from the long-term seasonal median or changing rapidly. It never increases the score.
