The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Asia/Tbilisi local. Folk tradition, not a scientific forecast.

Poti is Georgia's primary commercial port on the Black Sea, 75 km north of Batumi, at the mouth of the Rioni River — the largest river in the Caucasus. The city is defined by this geography: the freshwater plume of the Rioni discharges directly into the Black Sea here, creating a brackish transition zone that extends several kilometres offshore and strongly influences the nearshore environment. The port itself handles container, bulk, and Ro-Ro cargo, and is one of the key logistics nodes for the South Caucasus transit corridor linking Turkey and Azerbaijan. This is not a resort destination. It is a working port city surrounded by lowland forest and wetland. Water level at Poti is governed by the same principles as the rest of the Georgian Black Sea coast: the astronomical tide is under 10 cm — negligible. Wind setup and atmospheric pressure are the controlling variables, with sustained onshore southwesterlies adding 20–30 cm and offshore winds removing the same. The Rioni River discharge adds a separate freshwater signal: spring snowmelt from the Greater and Lesser Caucasus drives peak river flow in April–June, when the Rioni can discharge 1,200–1,800 cubic metres per second at the mouth. This creates a visible freshwater plume extending 5–10 km offshore, with salinity dropping from the Black Sea mean of 17–18 ppt to under 5 ppt in the river mouth zone. The plume suppresses coastal water temperature by 3–5 °C relative to the surrounding sea in the spring flood period. For anglers, Poti is one of the most productive locations on the Georgian coast. The Rioni estuary is a feeding ground for Black Sea species that exploit the nutrient-rich freshwater input: mullet (particularly thick-lipped grey mullet) concentrate in the river mouth and the shallow lagoon system behind the port. Black Sea trout — the local brown trout subspecies (Salmo labrax) — enter the lower Rioni on autumn and spring runs. The Paliastomi Lake, 5 km south of Poti and connected to the sea by a narrow channel, holds catfish, carp, and pike alongside the migratory marine species that use the channel. Wind-driven water level changes have some influence on the estuary: an onshore wind that raises the sea level by 20–30 cm backs up the river mouth and slows the outflow, increasing the depth in the estuary channels. Kayakers should be aware of the shipping traffic at Poti. The approach channels to the commercial port are active and buoyed; small craft must stay well clear of the main fairway. The coast north and south of the city is more accessible for paddling, though the low-lying swampy shoreline offers no landing points for 5–10 km in either direction. The river mouth itself — where the Rioni meets the sea — is navigable by kayak but the current on a spring snowmelt discharge is 3–5 knots in the main channel, requiring care. For photographers, Poti is raw material rather than a polished subject. The port infrastructure, the river mouth, the wetlands — all offer industrial and natural photography at the interface of a major river and an enclosed sea. The Kolkheti National Park, immediately south of the city, protects the Colchic rainforest and the Paliastomi wetland system; the park's coastal boardwalk provides access to the lake edge and the sea-channel connection. Swimming is not recommended near the Rioni mouth. The freshwater plume carries silt, river debris, and elevated bacterial counts particularly during high-flow periods. The beaches 3–5 km north of the city, away from the immediate river influence, are cleaner. Sea temperature at Poti tracks the Batumi curve with a 1–2 °C depression in spring due to the cold river discharge. All tide predictions for Poti come from the Open-Meteo Marine gridded model. Timing accuracy is ±45 minutes; height accuracy is ±0.3 m above Chart Datum. The astronomical tidal signal is under 10 cm here; wind-driven water level changes dominate and are not captured by the tide prediction.
