Lisbon's sea level varies due to tidal influences, but the average sea level is approximately 1.1 meters (3.6 feet) above the mean sea level, as measured by the Portuguese Hydrographic Institute. This level is subject to change due to factors such as climate change, land subsidence, and other environmental impacts. Monitoring efforts are ongoing to assess and respond to these changes over time.
