Buoyweather - Marine Weather screenshots
Buoyweather is a marine weather app from Surfline/Wavetrak, Inc. It is free to download, carries no ads, and offers in-app purchases. The pitch is simple: instead of settling for the nearest coastal station, you pick a point out on the water and get a forecast for that exact spot.
That point-based approach is the main reason to consider it. Most general weather apps treat the sea as an afterthought, giving you a city forecast and leaving you to guess what the wind is doing five miles offshore. Buoyweather is built around the idea that the water is the destination, not the edge of the map, and everything in it follows from that.
Forecasts anchored to a point you choose
The core mechanic is choosing a forecast location at any point offshore. You are not limited to a list of buoys or named harbors; the developer's framing is that any latitude and longitude over water can become your forecast point. For a captain planning a run to a specific fishing ground, or a sailor plotting a crossing, that is a meaningfully different tool from a coastal summary.
Once a point is set, the app returns a long-range marine forecast for it. The two windows on offer are 2-day and 7-day forecasts, and the same choice applies to the wind, wave and tide forecasts that sit alongside the main outlook. In other words, you are looking at the same point through several lenses rather than switching between separate screens for each type of data.
The developer bills this as accurate marine weather forecasting, and that is a claim worth treating as marketing rather than a measurement. The structure makes sense for offshore planning: wind, waves and tides are the three things that decide whether a day on the water is comfortable, marginal or simply off.
Saved spots and keeping them tidy
The supporting feature set is about repeat use. You can save unlimited favorite forecasts, which matters more than it sounds. Anyone who runs the same handful of grounds, channels or anchorages will want those points ready to open rather than re-entered each time.
Favorites can also be edited and organized for easy access. That suggests a setup where the points you care about most stay near the top and the ones you use occasionally can be tucked away, rather than one long undifferentiated list. It is a small thing, but it is the difference between an app you open on the dock and one you stop bothering with.
There is also a customer service address for questions and comments, which the developer invites feedback through. That is a normal support channel rather than a feature, but it is the stated route if something about the forecast or the app itself needs explaining.
What it asks of you: registration and the two-day limit
The app is free to download, but the forecast itself comes with a structure you should understand before installing. Free access covers two days of forecasts; premium unlocks the full seven. So the longer window is the paid tier, and the free tier is the shorter one.
In-app purchases are present. I would go in expecting to check the current terms in the app rather than assuming a figure. The absence of ads is worth noting as a positive.
The practical consequence is that the free experience is a two-day planning tool. If your trips are decided a day or two out, that may be entirely sufficient. If you are watching a weather window develop across a week, the 7-day view is the part you would be paying for, and that is the decision the app ultimately asks you to make.
Getting useful answers out of it
The best way to use a point-based forecast is to set your points before you need them. Save the grounds, passes and anchorages you actually run, organize them so the regular ones are quick to reach, and the app becomes a two-tap check rather than a data-entry exercise when you are trying to leave the dock.
When you do look, read the wind, wave and tide forecasts together rather than in isolation. A manageable wind with an awkward tide at your chosen point is a different proposition from the same wind with the water moving your way, and the app gives you all three for the same coordinates. The 2-day view is the one you will lean on most if you stay on the free tier, so it pays to check it at a consistent time each day rather than at random.
It is also worth remembering what a forecast is: an outlook for a point, not a guarantee for your route. The value here is that the point is one you chose because it matters to you, which is a better starting position than a forecast for the nearest town on the coast.
On reception, the app sits at a 2.1 average across 411 ratings, with more than 100,000 installs. That is a low score for a tool with this much history, and it is the kind of signal a prospective user should weigh rather than dismiss.
A planning tool for people who name their coordinates
Buoyweather makes most sense for boaters, anglers and sailors who think in terms of specific offshore points rather than a general stretch of coast. If your plans hinge on what the wind and swell are doing at a particular latitude and longitude, the app's whole design is pointed at that question, and the saved-favorites system rewards the kind of repeat trips those users tend to make.
The trade-off is the tiering. Free registration gets you 2-day forecasts; the full week sits behind a premium conversion, and in-app purchases are part of the deal. Anyone whose decisions are made a day or two ahead can work within the free tier comfortably, while week-ahead planning is where the paid option comes into play.
I would treat the 2.1 rating as a reason to look carefully rather than a reason to walk away. The app does one job in a specific way, and for the right user that specificity is the point.
The short verdict
A focused marine forecast tool for boaters who plan around specific offshore points, with the full week behind a premium conversion.

Buoyweather - Marine Weather: frequently asked questions
How do I pick a forecast location in Buoyweather?
Choose a point over water, and the app returns a marine forecast for it. There is no requirement to pick from a fixed list of buoys or harbors, so the location can be wherever you actually intend to be. Once you have a point you like, you can save it as a favorite.
What do the free and premium versions include?
Registering gives you access to 2-day forecasts at no cost. Converting to premium extends that to the full 7 days. The app is free to download and offers in-app purchases, so the longer forecast window is the part tied to paying.
What kind of forecast data does the app show?
Alongside the main marine outlook, it provides wind, wave and tide forecasts for your chosen point. Each of those is available in either the 2-day or the 7-day window, matching the forecast length you have access to. Reading them together gives a fuller picture of conditions at that spot.
Can I keep more than one location saved?
Yes. The app lets you save unlimited favorite forecasts, so you are not restricted to a single point. You can also edit and organize those favorites to keep the ones you use most within easy reach.
What changed in the most recent update?
The latest release fixes a few bugs and makes some minor interface improvements. It is a maintenance update rather than a change to how forecasting works.
