CatchWindow fishing intelligence

Billingsgate, London Daily Water Report — October 7, 2026

Billingsgate gets a qualified green light for sheltered-water plans: kayaking and boating are the strongest fits, with diving also rating well, but the late-day gust risk and poor atmospheric visibility keep this from being a carefree all-day outing. The water forecast is flat throughout, with 0.0 m waves, no swell and no wind waves indicated. That is the main reason kayaking scores 8.0/10 and boating 7.8/10. The representative northerly wind is only 2 knots, though it is not a day to treat that number as the whole story: winds range up to 11.3 knots and gusts are forecast to reach 23.5 knots around 18:00. The better practical window is therefore from dawn through the afternoon, before the evening gustier turn. Cloud cover is complete, rain is possible from 08:00 to 19:00 despite a representative total of 0 mm, and atmospheric visibility is only 4.1 km. That visibility figure is for the air, not a measure of underwater clarity. Diving holds at 7.6/10, unchanged from each of the previous seven CatchWindow reports, supported by the flat marine forecast and light representative wind. Still, no sea-surface temperature or water-clarity reading is available, so conditions below the surface cannot be confirmed from this report. Fishing is middling at 5.9/10, with the more useful solunar major period running 09:19–11:19; a second major period follows at 21:19–23:19, after sunset and alongside the forecast gustier evening conditions. No tide data is available, an important missing piece for harbour timing. Sailing is only a 5.2/10 proposition: calm water is welcome, but very light winds offer little drive, while the broad gust spread later makes the day less tidy than it first appears. Pressure is stable near 1012 hPa, notably lower than the 1020.2 hPa recorded in yesterday’s historical comparison, while boating, fishing and sailing scores all ease from yesterday. Kayaking improves slightly from 7.7/10. Thursday through Sunday remain wave-free in the marine forecast, with generally modest peak winds; Friday stands out for a 72% precipitation chance. Best bet: launch early for a flat-water paddle, be off the water well before the 18:00 gusts start showing their teeth.
