I'm not used to seeing coconuts hanging off trees. Some local councils in Queensland are so terrified of law-suits that they have them pruned on a regular basis despite a huge lack of evidence to support the contention that they're dangerous. The city council at Nouméa obviously doesn't give a rats about them, here's a fine bunch pictured in the Place des Cocotiers in the centre of the city.
We only ventured onto the beach a few times on our holiday and on one such very windy occasion we finally got our beach towels under control only to look straight up at rather unnerving masses of coconuts. A quick and dirty risk analysis and the lack of travel insurance promptly caused us to retire to the hotel pool surrounds. However, a couple of days later we went for a stroll along some back streets after tea and witnessed a coconut fall from a height of about 10 metres straight onto the roof of a nearby minibus where it made a hell of a noise (and presumably a fair dent). There was no wind, it simply became a victim to the force of gravity. Dangerous or not, I sure as hell wouldn't have wanted to cop that one on the noggin.
