CatchWindow fishing intelligence

Billingsgate, London Daily Water Report — October 5, 2026

Billingsgate gets a firm green light for boating, with kayaking, sailing and diving also well placed—but treat the glassy forecast as a comfort, not a substitute for harbour awareness. The marine forecast holds wave height, swell and wind waves at 0 m throughout the day, while a light WSW wind averages about 5 knots. That combination earns boating the day’s best activity score at 8.1/10, with kayaking 7.1 and sailing 7/10. The most agreeable stretch should run from dawn into late morning: daylight begins around 06:33, sunrise is 07:06, and the first solunar major period runs 07:36–09:36. Winds remain light across the day, though gusts are forecast to top out near 15.6 knots around 13:00, so the middle of the day is the point to keep an eye on rather than assume conditions will stay perfectly polite. No rain is indicated, skies are forecast clear, and air temperatures rise from the low teens toward 22 C. Atmospheric visibility is forecast near 11 km, useful for surface awareness but not a measure of underwater visibility. Fishing is a reasonable rather than standout proposition at 6.1/10. The morning major period is the clearest timing cue, with a shorter minor period at 14:06–15:06; a second major period arrives after dusk, 19:36–21:36. Pressure is high near 1026 hPa but falling, and without tide data there is no basis for calling a tide-led bite window. Wildlife scores 6.6/10, likewise with no tide information available to refine the timing. Divers receive a steady 7.6/10, unchanged from the reconstructed scores across the previous week. Flat surface conditions help, but water temperature and clarity data are unavailable, so plan exposure and visibility expectations independently. Boating is slightly down from yesterday’s 8.6, while sailing improves notably from 5.6 as the breeze becomes more usable without becoming rough. Tuesday stays very light-wind and flat, then Wednesday brings a much wetter forecast with an 86% precipitation chance and stronger winds. The flat marine outlook persists through the coming week, but air temperatures trend cooler after Tuesday. Best bet: launch early, enjoy the near-zero sea state through the morning solunar window, and be back with a warm drink before the afternoon gusts decide to audition.
