Weather…

Lake Güija is a large lake of volcanic origin shared between El Salvador and Guatemala, forming a natural border between the two nations. Covering approximately 44 square kilometers, it is situated at an elevation of 430 meters above sea level. The lake was created when prehistoric lava flows from the San Diego volcano obstructed the natural drainage of the Ostúa and Angue rivers. It is framed by a dramatic landscape of volcanic cones and dry tropical forests. Beyond its ecological value, the lake is a site of immense archaeological significance; the peninsula of Igualtepeque contains hundreds of ancient petroglyphs, suggesting it was a major ceremonial center for pre-Columbian cultures. The lake supports a rich variety of aquatic life and serves as a vital wintering ground for migratory waterfowl. The surrounding communities rely on artisanal fishing and seasonal tourism. In recent years, binational environmental groups have worked to address water quality issues arising from industrial and mining runoff from tributary rivers originating in Guatemala.
