Sea Level Observation

Sea Level Observation at Colombo

The graph illustrates daily sea level variations recorded at the Colombo tide gauge station, Sri Lanka, from 2017 to mid-2025. The blue line represents tide gauge observations, while the green line shows satellite observations of the Global Ocean Gridded Sea Surface Height data from the Copernicus Climate Service.

Seasonal Sea Level Variation on the West Coast of Sri Lanka

The graph shows the seasonal changes in sea level along Sri Lanka’s west coast, based on monthly average sea level observations.
