The Apple Weather app absolutely sucks. I have learned to ignore its predictions. It will say that it's sunny outside, and I'll look out the window, and we're having a hailstorm.

Can anyone recommend a good app to replace it? No ads, lightweight etc.

https://weather-sense.leftium.com: just a web app, but you can add it to your home screen to access like an app[1]

Fortunately someone recreated a clone at https://merrysky.net , which was featured [1] on HN some time ago. I've used it daily since. [1] https://news.ycombinator.com/item?id=34155191

Thanks for the mention! I'm the author of merrysky. Opened to feedback. What would you say you miss the most?

The Apple Weather app has gotten better over time, though it’s still not a perfect replacement. Scrolling through the Dark Sky screenshots, I can recognize many of the same things now incorporated with Apple’s. And Apple does offer location specific notifications of rain which I find to be pretty accurate, about as accurate as Dark Sky. There’s largely a perception problem with Apple. People loved Dark Sky as an inde…

I still think DarkSky made it easier to visualize the day. With Apple, when I tap on a day to see the details, the temperature and rain forecasts are in two separate graphs, instead of being unified into one easily glanceable view. This is what I really liked about DarkSky. I didn’t have to read and understand the forecast, I could simply glance at it and intuitively have an understanding of the day’s weather. Apple…

I designed https://weather-sense.leftium.com to make it easier to visualize both the day and week.

Even without any text labels, you should be able to get a feel for what the weather is and how it will change:

- Hourly plots like Dark Sky, with everything (temperature, rain, AQI, weather conditions) in a single plot.

- The change in temperature visualized with both color and space. Space is obvious (higher -> hotter); color ranges from red for hottest to blue for coldest. All the visible plots share the same color-temperature mapping. So the gradient block to the left shows both the temperature range for that day as well as how it compares to other days.

- Finally, there is a weekly overview at the top.

Inspired by MerrySky: https://weather-sense.leftium.com Some differences: - Shows weather from yesterday for comparison - All hourly plot trackers connected; not just the top one - Includes AQI - Sky color visualization (try scrubbing across dawn/dusk!) - Non-precipitation colors approximate sky color (haziness) - Temperature variation visualized both spatially and with colors - Data source is Open Meteo - Planned: 6…

There's no obvious way to change the location of the prediction. Can it be done, to support the "travelling soon" use cases?

One of the things that made Dark Sky so great was its simplicity and focus. Apple Weather has added many of DS’s features over the past few years, but it’s so much more busy and dense with information. This is a problem that Carrot Weather and many of the other apps mentioned in the comments here also have. There was something very special about that app, and I really do miss it (also Apollo, Google Reader, Gaia GPS,…

On https://weather-sense.leftium.com the colored boxes in the legend at the top are actually checkboxes.

Toggle only the stats you're interested in! The toggle is persisted to localStorage.

I plan to add more stats, like wind speed and direction, but they will all be toggle-able.

For anyone mourning Dark Sky, I make Weathergraph - visual weather app, which has the Dark Sky-like vertical view as an optional data layout.

It's shown in the middle screenshot at https://weathergraph.app (on desktop, mobile users can check https://impresskit.net/image-download/9161183f-e118-4c75-8f8... )

Yes, but currently only possible via url param:

n is short for "name" and uses the Open Meteo geocoding API[1].

I’m surprised how many places in the world measure rain in percentage chance. Must be a metropolitan concept. Here in Denmark, weather reports estimate mm/hr - the amount of rain. Maybe it’s our agricultural inheritance?

https://weather-sense.leftium.com shows both mm/hr and percentage chance.

I've noticed there is a correlation, but having both is useful:

- Often there is a percentage chance, but the mm/hr is 0. At these times, it could rain but will probably be very light.

- Less common, but sometimes there is 0% chance, but a non-zero mm/hr.

> It removes a sense of artificial precision that doesn’t really exist because weather forecasts fundamentally have very high uncertainty and error bands.

So true.

Open Meteo supports 28 different WMO weather condition codes[1]. Most weather apps only support half as many. (Just "rain" instead of light/moderate/heavy rain.)

Showing all 28 is less helpful because of the noise. More useful just to show it might rain for a period of several hours vs oscillating between light rain and heavy rain. The light vs heavy precision wasn't worth it when there was high uncertainty whether it would even rain at all.

So https://weather-sense.leftium.com consolidates hours with similar weather conditions into a single segment by default. You can click on the weather icons at the left of the plots to toggle the original unconsolidated view.
