With the mercury shooting through the roof, Goa's private lifeguard agency issued on Thursday an advisory for the hundreds of thousands of tourists and locals who head for the beaches in summer, especially in May, when the temperature in the coastal state peaks at 38-40 degrees Celsius.

The advisory asks tourists to look out for rip tides and powerful underwater currents that are a major cause for drowning off beaches -- a regular phenomenon in summer, while also advising swimmers and beach-goers to stay hydrated and avoid direct sunlight.
