My GO / NO-GO verdicts are often wrong.

First, use the two explainers. The information button beside the GO / NO-GO stamp opens “Why this rating?”, which names the window it found and what held it back. Each row in the hourly forecast has a “Why this verdict?” button that checks off every limit for that hour, one by one. Between them they show exactly which threshold decided the answer.

Your verdicts depend on several weather, solar and tide sources and on the thresholds you set. Aweigh offers predictions, not guarantees — but most rating errors turn out to be thresholds that do not match how you actually boat. Check the wind limits first. If sea state is being ignored, check whether Waves Max is still 0, which means no wave limit at all. Make sure the numbers are sensible for each vessel: they should usually differ from one boat to the next, and from one season to the next.

It’s raining but my Aweigh rating says GO.

Check the Precip Chance limit on the vessel you are viewing. If it is set high, a rainy hour can still pass. Bear in mind that this is a chance of precipitation, not an amount — a 40% hour is a forecast of odds, and rain falling on you now is a certainty no forecast can overrule.

Fog is shown but never judged. When the air is close enough to the water temperature for sea fog, Aweigh marks the hour, and it leaves the decision to you rather than failing the hour on your behalf.

Aweigh draws on several weather sources and gives you predictive information to make your own decisions. Always watch the sky, dress for the conditions, and use your own judgment on the water.

It’s going to be a beautiful sunset, but Aweigh says NO-GO.

Each vessel has a Daylight only setting, and it starts switched on. With it on, hours before sunrise and after sunset cannot count toward a Go. So if the clear stretch you need — your Window Hours — would run past sunset, the verdict falls to NO-GO even under a perfect sky.

If you go out after dark, switch Daylight only off for that vessel and the dark hours will be rated like any others. Whether to enjoy the sunset from the boat or from the dock is still your call.

My GO / NO-GO ratings are not considering the temperature.

That is deliberate. Air and water temperature are shown on the forecast but are not part of the GO / NO-GO rating, because there is no threshold that would be right for everyone. Too hot or too cold to head out depends on the vessel, the location, the season, the daylight, the wind, and on your own skills and clothing.

Always weigh air and water temperature, the season and your distance from shore when you set your thresholds and when you decide. Whatever the boat, the conditions or the activity, boating always carries a risk of getting wet and of ending up in the water. Aweigh does not recommend recreational boating in extreme conditions, including cold air or cold water. Avoid unsafe conditions, carry proper provisions and safety gear, and take precautions against hypothermia and heat stroke.

I see “Weather service unavailable” or a day with no forecast.

Aweigh does not make its own weather. Every number on the forecast comes from a third-party service — a weather model for wind and temperature, the National Weather Service for rain chance and alerts, NOAA for tides — and when one of those services is slow or down, the day it would have filled goes dark rather than showing a guess. If Aweigh fetched that day within the last 24 hours, it shows that reading instead, with a notice saying when it was taken. That message almost always means one of our data providers is having difficulties, not that anything is wrong on your end or with your account.

Wait a few minutes and reload. Today and tomorrow often keep working through an outage because a second weather source covers the next 48 hours, while days further out may be blank until the primary service recovers. If it lasts more than an hour, please send us feedback with the location and the day you were viewing. Our data lists every service behind the forecast.

Aweigh is not saving my threshold settings.

Settings are saved to an account. Without one you are seeing the defaults, and any change lasts only as long as the visit. Use the account button at the top right of the forecast to create an account — it takes a moment, and the Terms are linked from the signup form.

If you have an account and settings still are not sticking, check that you are signed in: the same button shows your initials once you are. Tick Stay signed in when you sign in on your own phone so you are not signed out between visits.

I’ve checked all my thresholds for each vessel and my GO / NO-GO ratings are still wrong.

Visit aweighweather.com for fuller instructions on using Aweigh. And please send us feedback — a verdict that still looks wrong after the thresholds check out is something we want to see, and telling us where you were and what you expected is what makes it findable.
