Geo Detail: A spindle-shaped barrier island off the Bay of Bengal coast in the Tirupati district of Andhra Pradesh. It separates the Pulicat Lake from the Bay of Bengal and is chosen for its proximity to the equator and eastward launch azimuth.
Pulicat Lake
Type: lake
Context: The second largest brackish water lagoon in India, which is separated from the Bay of Bengal by the barrier island of Sriharikota.

On the Map

Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh, India

Climate & Geology

The region experiences a tropical wet and dry climate (Köppen Aw/As) with hot summers and mild winters, heavily influenced by both the Southwest and Northeast monsoons. Geologically, it is a stable coastal barrier island composed of quaternary sands and silts, with low seismic vulnerability (Zone II/III). However, its coastal location makes it highly susceptible to tropical cyclones originating in the Bay of Bengal.

Physical Context

Sriharikota is a barrier island located off the eastern coast of India in the Tirupati district of Andhra Pradesh, separating the brackish Pulicat Lake from the Bay of Bengal. Its strategic coastal position provides a safe eastward launch corridor over the ocean, minimizing risks to populated landmasses.

Resource Significance

The surrounding Pulicat Lake is a highly productive brackish water ecosystem supporting local fisheries and the Pulicat Lake Bird Sanctuary, which is a vital habitat for migratory birds. Economically, the geography is of immense strategic importance as it houses the Satish Dhawan Space Centre (SDSC-SHAR), India's primary spaceport, which drives high-tech manufacturing, employment, and regional development.
