Few South Pacific islands have surf beaches like this: soft golden sand (not crushed coral), clear turquoise water and real waves (though conditions make it fickle for the travelling surfer; it’s usually only islanders who catch it when it’s “on”).
At the very least, you can bodysurf here anytime. Just beware of currents and rips, and never swim solo. Like Lord Howe’s other beaches, it’s unpatrolled (i.e. there are no lifeguards).
You won’t be completely alone, however. Thousands of sooty terns nest in the sand dunes at Blinkys. Between September and January you can see the chicks, but be prepared to be dive-bombed by protective parents if you get too close.
