Secretary, Ministry of Earth Science, Government of India inaugurated the TIDE PREDICTION
SYSTEM FOR INDIAN SUBCONTINENT on 20 July 2010. Information on predicted ocean tides
(for five days) for a number of stations along the coastline of the Indian subcontinent is now routinely
disseminated through the web (as time series plots / High Low listings) by Indian National Centre for
Ocean Information Services (Ministry of Earth Sciences, Government of India), Hyderabad. The basic
data used for the purpose is the tidal harmonic constants (amplitude and phase) from National Institute
of Oceanography (NIO), Goa. Out of the 178 stations, for which the data is presently available, there
are 136 Ind ian stations. The other countries for which predicted tidal information is available:
Myanmar (12), Sri Lanka (11), Bangladesh (9), Chagos (5), Pakistan (4) and Maldives (1). This
information also will be disseminated through Electronic Display Boards in local languages. The
predicted tides will be also compared with observations in real time.
