18,749-acre Humber Mouth. Spurn fishing map with Environment Agency multibeam/SurfZone ODN contours (61.92% measured, 96.99% assessed), four measured spots, exact EA TraC occurrence, three dated survey cards, official access and current GOV.UK/applicable IFCA guidance. The water tops out around 106 ft. The depth chart comes from Environment Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Humber Mouth - Spurn runs 18,699 acres with 58.2 miles of edge — 18 islands included. A development index of 3 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 53% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 11.3 mi long by 4.1 mi wide at the broadest reach. Closest neighbour on DepthScout: Covenham Reservoir, 9 mi south of here.
In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 20 to 60 ft for winter. Summer atlantic herring concentrate at Directly measured lower-channel shoulder, a good-rated channel edge around 43 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a herring feather rig or a small silver jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Directly measured upper-flat transition (5 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Directly measured lower-channel shoulder (43 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Directly measured lower-channel shoulder (43 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Directly measured lower-channel shoulder (43 ft) | Small silver jig, Sparse feather rig |
Spring puts european plaice in skinny water — 8 to 35 ft is the zone. As the season builds they drop to 6 to 40 ft, wintering in 25 to 80 ft. Fall european plaice concentrate at Directly measured lower-channel shoulder, a prime-rated channel edge around 43 ft. Warm-month bites cluster around early morning and the evening. A light spooned bottom rig or a beaded trace covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | Directly measured upper-flat transition (5 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Directly measured upper-flat transition (5 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | Directly measured lower-channel shoulder (43 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | Directly measured lower-channel shoulder (43 ft) |
Early season european flounder use the shallows, holding in 5 to 25 ft. Summer is a 6 to 35 ft game here, winter a 15 to 50 ft one. The chart's best answer is Directly measured upper-flat transition — feeding flat, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Directly measured upper-flat transition (5 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Directly measured upper-flat transition (5 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Directly measured upper-flat transition (5 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Directly measured lower-channel shoulder (43 ft) | Small bottom jig |
Early season european smelt use the shallows, holding in 3 to 25 ft. Expect a summer slide to 25 to 70 ft, then a winter hold in 20 to 65 ft. Put Directly measured lower-channel shoulder first on the milk run — a channel edge near 43 ft that grades good for fall. In summer the feeding windows fall in early morning and the evening. Tie on a tiny vertical spoon or a micro jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | night & dusk | open water | Micro silver jig, Tiny feather rig |
| Summer | 25 to 70 ft | dawn & dusk | Directly measured lower-channel shoulder (43 ft) | Tiny vertical spoon, Micro jig |
| Fall | 15 to 55 ft | dusk | Directly measured lower-channel shoulder (43 ft) | Micro jig, Tiny silver spoon |
| Winter | 20 to 65 ft | dusk | Directly measured lower-channel shoulder (43 ft) | Tiny glow jig, Micro ice spoon |
When the water first warms, common sole slide up into 6 to 30 ft. There's no big seasonal slide here — summer means 3 to 30 ft, winter 20 to 70 ft. If you only fish one area, make it Directly measured upper-flat transition: a feeding flat around 5 ft that scores prime in summer. In summer the feeding windows fall in the evening. Keep a light rolling-lead rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | Directly measured upper-flat transition (5 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Directly measured upper-flat transition (5 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | Directly measured lower-channel shoulder (43 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | Directly measured lower-channel shoulder (43 ft) |
In spring, european seabass run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 2 to 30 ft before dropping to 10 to 55 ft for winter. Winter european seabass concentrate at Directly measured lower-channel shoulder, a prime-rated channel edge around 43 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a surface lure or a paddle-tail soft plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Directly measured upper-flat transition (5 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Directly measured upper-flat transition (5 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Directly measured lower-channel shoulder (43 ft) | Slim metal lure, Minnow plug |
