Port Chicago, CA Daily Water Report — October 4, 2026

Port Chicago gets a firm green light for boats, paddles and calm-water plans today, with the important caveat that a high-scoring day is not a substitute for local judgment. The marine forecast is flat: 0 m waves, swell and wind waves, alongside a modest current of about 0.08 m/s toward 225 degrees. West-southwest winds are generally light, 1.4–7 knots, though gusts may reach 14.6 knots around 11 AM. That makes early morning the cleaner, less fussy window before the day heats up and the gust potential arrives. Boating leads the board at 9.1/10, matching its best score in the supplied recent history. Kayaking is also strong at 8.4/10, just above yesterday, while diving holds at 8.2/10 for a second day. The flat-water forecast and light winds support those scores; marine SST is 21.4 C, notably 3.7 C above average. No underwater-visibility measurement is supplied, however, so do not confuse the forecast 44.4 km atmospheric visibility with what conditions may look like below the surface. For anglers, the better timing is the morning solunar major period from 7:08–9:08 AM, overlapping the rising tide toward the 10:25 AM high of 1.15 m. A second major period runs 7:08–9:08 PM, spanning the evening rise toward the 8:48 PM high of 1.40 m. Fishing rates 6.9/10, an improvement from yesterday’s 6/10 but still short of the stronger 7.2 recorded on October 1. Pressure is rising near 1013 hPa, and rain is not indicated. Sailing earns 7/10: pleasant for light-air expectations, but not a day to count on sustained breeze. Wildlife scores 7.1/10, with the 3:16 PM low tide and the 1:38–2:38 PM minor solunar period offering a reasonable shoreline-exploration window. Expect heat to be the day’s most obvious non-marine complication, with air temperatures forecast from 18.3 to 34.9 C under clear skies. The next several days stay remarkably flat, dry and light-winded, while daytime heat builds into the mid-to-upper 30s C by midweek. Best bet: launch early, use the calm water before late-morning gusts and heat, and let the rising morning tide carry the day.
