Tahit and Moorea are very benign sailing areas as long as there is not a tropical cyclone in the offing. Winds tend to be moderate and the weather
almost always delightful. The passes are well marked and the bays deep and easily navigated unless you want to venture into quite shallow waters. Even then, it's easy to gunk hole if you have someone at the spreaders to read the water
color and spot coral
heads. The Tuamotus can be a challenge because of their low profile on the leeward side. GPS
has pretty much done away with the navigational issues that garnered them the 'Dangerous Archipelago' moniker, however. Navigating inside the lagoon
takes some vigilance but still doable for a single
hander if you stay in the channels and don't wander too far afield. The Marquesas
are also a delightful group of volcanic islands with similar sailing conditions to Tahiti though the anchorages
are not as protected.
The southern summer, November to April can bring some nasty weather
especially in a full blown El Nino period. Plenty of protected anchorages
and good holding so not as quite as bad as other areas. We were there at the beginning of an El Nino and experienced only one spate of bad weather from a tropical depression. We were tucked snugly deep in a Opunohu Bay on Moorea. Even though winds were reported as a steady 50k at the height of the storm, we were secure and comfortable throughout. The following year, with the El Nino fully developed, was not so benign. They experienced 3 full blown cyclones with hurricane
force winds. Still the cruising boats seemed to make out okay, not so good for the local's roofs, however.
To sum it up, Tahiti is a great place to get your sea legs with a number of Islands and Island groups to explore in mostly ideal conditions.
