Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

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 Africa/Windhoek local. Folk tradition, not a scientific forecast.

Last spring tide on Tue 19 May (range 1.4m). Next neap on Sat 23 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Kolmanskop is 10 kilometres east of Lüderitz, accessible by permit through the Sperrgebiet — the Forbidden Area of the Namibian diamond coast. What makes it one of the most photographed abandoned settlements in the world is straightforwardly physical: Namib sand dunes have filled the colonial buildings to window height, poured through doorways in smooth frozen waves, and buried walls to their eaves. The rooms are half-full of sand. The wallpaper is peeling in the still, dry air. The ballroom floor has buckled under 70 years of sand pressure. This is not ruin porn — it is a genuinely unusual juxtaposition of colonial domesticity and geological process, and it is worth the permit. Kolmanskop was built between 1908 and 1912 after the diamond discovery that transformed the entire southern Namibian coast. The diamonds at Kolmanskop were not found at Kolmanskop itself — they were surface deposits scattered across the desert gravel, picked up by hand in the early days of the rush. The town was the administrative and residential centre for the surrounding diamond field. At its peak in the 1910s, it held a hospital with the first X-ray machine in the southern hemisphere, a school, a casino, a ballroom, a skittle alley, and an ice factory — an improbable assemblage of civilised amenity in the Namib gravel plain. The coastal connection is the reason the diamonds exist here at all. Over millions of years, rivers flowing from the Namibian interior carried diamonds eroded from kimberlite pipes in the interior and deposited them in river gravels, eventually transporting them to the coast and into the ocean. The surf and longshore drift then sorted and concentrated the stones in beach gravels. The richest deposits were surface deposits in the dry coastal Namib where wind had removed the lighter sediment, leaving the diamond-bearing gravel concentrated. Today the same material is recovered offshore by marine dredge vessels working the Namibian continental shelf — Kolmanskop's diamond story continues underwater, 30 to 150 metres below sea level, where the seabed holds the reworked gravel deposits that the ancient rivers delivered. The Sperrgebiet (Forbidden Area) was demarcated in 1908 to protect the diamond fields from illegal mining. The restricted zone covers most of the southern Namibian coast from Lüderitz to the Orange River — an area larger than Switzerland. In 2008 the zone was redesignated as Sperrgebiet National Park, opening limited access under permit while retaining the mining concession in most of the area. The park contains some of the most undisturbed desert landscape in Africa, including coastal areas that have had no human access for over a century. The flora of the southern Namib — quartz plains, succulent karoo plants, the extraordinary Welwitschia mirabilis — is largely intact within the zone. The guided tour of Kolmanskop takes approximately one hour and covers the main residential buildings, the hospital, the recreation facilities, and the dune-filled interior rooms that are the principal photographic subjects. The morning tour (07:00 or 08:00 departure from Lüderitz) is preferred by photographers because the low-angle light enters the room interiors through the windows and illuminates the sand dunes within — late morning and afternoon light is flatter and less dramatic in the room interiors. The permit system is managed by Lüderitz Safaris and Tours; independent entry without a guide is not permitted. There are no tidal dynamics at Kolmanskop — the site is 10 kilometres inland and 160 metres above sea level. Its inclusion on TideTurtle is justified by the coastal context: the diamond coast geology that makes Kolmanskop historically significant is the same process that drives the marine dredging visible from Lüderitz harbour and shapes the entire southern Namibian coastal economy. The site is the most accessible window into that geology and that history for visitors based in Lüderitz. The Benguela Current, the Sperrgebiet, and the marine diamond industry are all part of the same system. The cold water suppresses evaporation, keeps the coast hyperarid, and preserves both the buildings and the diamond gravel concentrations in the seabed. The abandoned hospital with its original X-ray equipment in the dry air, the dunes filling the ballroom, and the dredge vessel working the offshore gravel bank 30 kilometres away are connected by geology and by the specific conditions of the southern Benguela coast. Predictions for Lüderitz (the nearest coastal reference) come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. The authoritative national sources for tidal and maritime data on the Namibian coast are the Namibian Meteorological Service and the Namibia Ports Authority.
