If you are booking Kauai for the winter, you have probably read that it rains. It does. What most guides skip is where it rains, how long it lasts, and what that means for your day.
Here is the version we give guests at the counter.
What winter actually means here
Hawaii really has two seasons. The National Weather Service in Honolulu calls May through October summer and October through April winter, and winter is when the heaviest rain arrives.
That sounds worse than it is. According to the Weather Service, winter rain rarely lasts more than a few hours, and normal trade wind weather still holds about half the time. The coolest months are February and March, and even then the temperature does not move much from the rest of the year.
Why the South Shore is the drier side
Kauai's weather depends on which side of the island you are on. The trade winds push clouds into the mountains, and the rain falls on the windward side and up high. The leeward side, where we are, tends to stay sunnier and drier.
The numbers back that up. The state's rain gauge in Koloa, just up the road from us, averaged about 54 inches a year from 2003 to 2021. Princeville on the North Shore averaged about 78 over the same years. Koloa came in drier in every one of those nineteen years.
So it is not that the South Shore never sees rain. It is that you have better odds here than almost anywhere else on the island.
The honest exception
Every so often a winter storm swings the winds around to the south. Those are the days the South Shore can catch the weather instead of dodging it.
If there is a storm watch or a big system sitting over the island, that is not a riding day, and we will say so. Short of that, most showers pass quickly and you can get on your way.
What winter riding is actually like
Honestly, it is one of the nicer times to ride. Cooler days mean a less hot and sweaty trip along the coast or up into Old Koloa Town.
Rain comes and goes. If the weather looks iffy the morning you plan to ride, bring a rain jacket. There are places along most of our routes where you can duck for cover in a downpour, but we will not promise you will stay dry if a shower rolls through. Usually it passes and you carry on.
Which rides work on a wet day
Nearly all of them. Every route we give guests runs on road or sidewalk, so even after rain you get where you are going without coming back covered in mud.
The one to skip is the Maha'ulepu Heritage Trail. The ride out is fine, but the walk is on sand, dirt and rock, and it gets muddy after rain. Save that one for a dry morning.
Be back before dark
This is the part that matters most in winter. The sun goes down around six in December and January, much earlier than people expect in Hawaii.
Riding after dark is not something we recommend. Bikes can come back as late as 8pm, but in winter, check the sunset time for the day you are riding and give yourself and your ohana enough time to get back to the shop before it gets dark. Safety comes first.
What else winter brings
Winter is whale season. Humpbacks are around from November through April, and you can watch them from shore a few minutes' ride from our shop.
It is also when the big surf shows up on Kauai's north and west shores. The Weather Service puts the South Shore's surf season in summer, so winter here is a different ocean from the giant waves you see in photos from the North Shore. Conditions still change day to day, so check with the lifeguards before you get in.
Conditions right now
As of October 2026.
Hurricane Lowell came through the South Shore in September, and the west end of the coast took the worst of it. Lawai Road out to Spouting Horn is open again, but expect a bumpy ride while the county repaves it. The county is also rebuilding Poipu Road in front of our shop, so walk your bike through the heavy sections and follow the road crew. Our guide to getting around Poipu without a car has the routes we are giving guests and a map.
The practical bits
We are open Tuesday through Sunday, 9am to 3pm, closed Mondays, and bikes can come back as late as 8pm.
Electric bikes start at $50 and regular bikes at $20, from two hours up to a full week. Helmets and locks are included. If riding over from your hotel or condo does not suit you, we deliver across the South Shore for a $50 delivery fee.
If the forecast has you worried, you can cancel or change your reservation at least 24 hours before your rental for a full refund. Inside 24 hours the rental is non-refundable, but we will do what we can to get you out on another day. Or just call us the morning of and we will tell you what the sky is doing over Poipu.
