Hydrographic Institute Publishes the 2026 Tide Table

The Portuguese Hydrographic Institute (IH) has published both volumes of the 2026 Tide Table, an essential tool for safe navigation and the planning of maritime activities. This publication is crucial for navigators, fishermen, water sports enthusiasts, and the planning of port operations, ensuring access to up-to-date tidal forecasts.

The published volumes were:

• Volume I – Portugal: includes tide forecasts for the main ports of mainland Portugal, Azores and Madeira.
• Volume II – Portuguese-speaking African Countries: dedicated to tidal predictions for the coasts of the PALOP countries.

Both volumes are available in print format at the IH’s Loja do Navegante (Rua Garcia de Orta 10, Lisbon), or as free digital downloads via the following links:
