Field notes
Small rock platform between Dover Heights and Vaucluse. Deepwater close in — drummer and groper on cunjevoi and crab, tailor and salmon spinning, the odd kingfish on live bait. Hazardous in any swell.

Situation. A trough has crossed Sydney Waters, and a low pressure system is forming within the trough off the south coast. The low will then head further offshore and remain over the Tasman Sea for the next several days, whipping fresh to strong southerly winds and large powerful waves to the coastline mid to late this week.
Tuesday 19 May until midnight. Winds: Southwesterly 15 to 20 knots. Seas: Below 0.5 metres. Weather: Partly cloudy.
Wednesday 20 May. Winds: Southwesterly 10 to 15 knots. Seas: Below 0.5 metres. Weather: Mostly sunny.
Thursday 21 May. Winds: Southwesterly 15 to 25 knots tending southerly 20 to 30 knots in the early afternoon then decreasing to 15 to 25 knots in the late afternoon. Seas: Below 0.5 metres. Weather: Partly cloudy. 80% chance of showers.

Best windows combine civil twilight with the hour either side of sun transit — the universal low-light feeding window most species respond to. Moon phase influence is folkloric; full and new moons coincide with the strongest tide swings.
