Mombasa tide gauge station

The Intergovernmental Oceanographic Commission (IOC) of UNESCO developed a Global Sea Level Observing System (GLOSS) program in 1985 to address the growing concern about the rise in mean sea level around the globe. The objective of GLOSS was to provide high quality standardized data from which valuable sea level products can be produced for international oceanographic programmes such as World Oceans Circulation Experiment (WOCE) and regional research programmes as well as for practical application on a national level. Kenya is one of the countries participating in GLOSS and has already received support and assistance in terms of training of our specialists and provision of equipment through IOC.

There are two sea level monitoring stations along the Kenyan coast being managed by Kenya Marine & Fisheries Research Institute (KMFRI). Mombasa tide gauge (LAT: 04o 04´S; LONG: 039o 039’E) was installed in 1986 and Lamu gauge (LAT: 02o 17´ S; LONG: 040o 54’ E) in 1996. Both Mombasa and Lamu are principal stations on the GLOSS network. Because of our close collaboration with University of Hawaii Sea Level Centre (UHSLC) in the United States, both stations have been upgraded and are transmitting data in real-time via satellite. The two stations are also dedicated components of the Indian Ocean Tsunami Warning System (IOTWS). Data from the two stations (and others like them in the region) can be used to either confirm or cancel a tsunami warning throughout the region.


This link provides 2017 Tide Predictions for Mombasa and Lamu produced by KMFRI. They are in form of high-low listings and hourly values. The predictions have been generated using special tidal analysis software (T_TIDE) with hourly and quality controlled time series of sea level observations from the two stations as input data. The heights presented in these tide tables are in meters above the lowest astronomical tide. The predictions are referenced to local time. Time zone for Mombasa and Lamu is GMT + 3 hours. KMFRI is distributing these predictions to all relevant and interested organizations as well as individuals dealing with marine environment to facilitate their research, navigational and recreational activities.
