CatchWindow fishing intelligence

Charleston, OR Daily Water Report — October 7, 2026

Charleston is a qualified go for fishing and wildlife watching, but a more guarded proposition for small craft and diving: the ocean is workable rather than gentle, with 1.3–1.9 m seas and a 1.32 m, 11.7-second northwest swell doing most of the heavy lifting. The strongest all-around window is late morning, roughly 9:54 AM to noon, when the major solunar period overlaps the 10:46 AM high tide. Fishing rates best at 7.4/10, supported by stable pressure near 1016 hPa, modest representative northerlies around 8 knots, and that favorable tide-and-solunar overlap. Wildlife also earns 7.2/10, with another useful opportunity around the 4:41 PM low tide and the 4:24–5:24 PM minor period. Those are suitability estimates, not promises of action on the water. Boating scores 6/10 and kayaking 5.5/10, reflecting the tradeoff: winds are generally manageable through much of the day, but the swell and short-period 0.44 m wind waves keep conditions from feeling casual. Gusts may reach 19 knots around 9 PM, so the late-evening high tide is not automatically the easy option. Sailing comes in at 6.2/10; there is enough breeze to work with, but gust spread, cloud cover, and sea state keep it below the stronger sailing scores seen earlier this week. Diving rates 6.6/10, down from 6.8 yesterday and 7.3–7.7 earlier in the recent record. Water is cold—marine SST is 11.5 C, while the supplied SST reading is 14.6 C—and surface conditions are not especially forgiving. Atmospheric visibility is only 0.1 km under complete cloud cover, which matters for transit and lookout, not underwater visibility. No rain is indicated, but the damp, cool feel is real: air temperatures run 10.3–15.7 C. Looking ahead, Thursday holds near-2 m seas, while Friday offers a possible easing window before another larger pulse Saturday and Sunday. The more attractive marine trend arrives Monday into Tuesday, with waves forecast around 1.3–1.7 m. Best bet: fish the late-morning high-tide solunar overlap, then let the swell—not optimism—set the rest of the day’s plan.
