Grenaa tide times

Approximately 0.4 m mean range on the outer Kattegat coast at Grenaa — slightly more than the sheltered Ebeltoft Vig but similar to Aarhus further south. The semidiurnal pattern gives two tidal cycles per day. Wind-driven surges, particularly from northerly directions, can add or subtract 0.3–0.5 m on top of the predicted tide and are worth monitoring alongside the tidal forecast.

The ferry from Grenaa to Anholt island (operated by Molslinjen) is primarily weather-dependent rather than tide-dependent, given the modest 0.4 m Kattegat range. However, strong northerly or northeasterly winds can delay or cancel sailings. The crossing takes approximately two hours and sailings are limited in number, so check the operator's live status and DMI's marine forecast before heading to the port — especially if travelling in autumn or winter when conditions deteriorate quickly.

Grenaa Strand, directly north of the town and harbour, is the main swimming beach — broad, sandy, and backed by low dunes. It is widest within two hours of low water when the full foreshore is exposed. Further north, the coastline becomes wilder and less visited, with longer dune-backed stretches accessible from parking areas off the coastal road. In calm summer conditions, any of these beaches is excellent; in a northerly blow, the outer coast takes the full Kattegat fetch, so check the DMI coastal forecast.

Anholt is a small island (about 22 km²) roughly 40 km offshore in the Kattegat, roughly equidistant between Denmark and Sweden. Most of the island is a protected nature reserve — a vast sandy heath and dune system with a small permanent population. The seal colony on the south side is the main draw for day-trippers. With limited ferry sailings (typically one or two per day in season), the tide table and weather forecast are both worth checking well in advance, as a missed ferry means a full extra day on the island or on the mainland.
