Hiking on Kauai any time of year is pretty much the same in terms of temperature. Light shorts and top that can get wet then dry multiple times during the day are the best.The key is to be aware and prepare for the conditions you might encounter. For camping / night long pants and some kind of hoodie are nice.My preferred stuff is Patagonia Capiline (other brands too) because it dries super quick and provides sun protection.
A few years back Captain Zodiak would drop people off at Kalalau to hike out.
Also, do you have any idea the general weather for that time of the year for hiking the trail? Yes - you should always attempt to get permits for camping.
The State DLNR does not make it easy, but at least you'll have a good story when the rangers check.
in Hawaiian - is one of the most beautiful and remote areas on Kaua‘i.
The strenuous eleven-mile Kalalau Trail winds along this rugged coastline, providing the only land access to legendary Kalalau Valley.
