2.6.1
26 February 2019

Complete weather forecast application.

Overview

Seasonality Core is the complete weather center for your Mac. View weather at any of the 34,000 built-in locations in more than 200 countries, or add your own custom weather location to view even more precise data. Seasonality gives you an accurate 7 day forecast, graphs of past weather conditions, a custom satellite/radar image, and much more. Seasonality Core's graphs are excellent at showing how weather conditions are changing over days, months, or even years. Seasonality Core will automatically collect and store weather data indefinitely. The custom satellite/radar image gives users the option to adjust opacity of both overlays, show the latest North American surface analysis, and view the global wind flow with Particle Mode.

Seasonality Core has a solid foundation from being in development for almost 10 years. We always welcome feedback, and have made countless improvements to the software over the years based on user suggestions. If Seasonality Core is missing something, we want to hear about it! Send your feedback to our support email.

What we're working on:

  • Higher resolution radar within the US
  • Improved radar coverage outside the US
  • Supporting personal weather stations
  • Weather watches and warnings
  • An even more flexible interface

I have been using Seasonality for a couple of year and this latest upgrade (Core 2.0) is absolutely beautiful. The interface is even more refined than in previous versions and the ability to expand the graphs and map windows is certainly a welcomed improvement. Another definite improvement is the current condition bar at the top of the screen. There are a lot of weather related programs and website out there but none is as elegant as Seasonality.

Doesn't work anymore, probably due to changes on sites it gets its info from. Emailed dev twice, but no answer. Abandonware or dev on holidays?

I like the way it illustrates detailed weather conditions throughout the world. As I travel a lot I need to know the most precise weather forecast, seems this app performs its functions pretty well. It's not too expensive and worth its price. I like it shows pressure and humidity, that is helpful for people who are affected by weather. Therefore, Seasonality Core is a great app to my mind.

This app is fun and full of details IF you are the kind to want to see them. If not, then select the Preferences and turn off what you don't need to know about. Wish the newspaper could do that. Highly recommended, IMHO. Thank you. Patrick

Seasonality Core is an information-packed weather monitoring application for diving deep into local and global weather conditions and patterns. The app grabs its weather information from the International Civil Aviation Organization (ICAO) nearest to your location. This does, of course, mean that you need to have an ICAO within reasonable distance of your vicinity, so users outside of North America may want to verify this within the app ahead of time. But as soon as your location is selected, you’re getting real-time information streamed into Seasonality Core, and there’s no shortage of weather data to explore. The most visually intriguing aspect of Seasonality Core is its “particle mode” view that features swirling wind movement vectors that are colored by temperature. It’s a fascinating view that is as interesting as it is informative; zoom out and you get a sense of global weather patterns. But as compelling as particle mode is, the information layout specific to your locale tops it in utility. Get multiple day forecasts and graphs that predict changes in everything from temperature to cloud cover to humidity. And for the real enthusiast, the ability to select and monitor cities from all over the world means you can get an intimate view of the conditions in places where loved ones live, or where you may one day move. Seasonality Core is a pleasant ride for the novice and a true powerhouse for the aficionado – give it a try!

This app is only useful if you have a compatible weather station in the area you're interested in. In the UK, there appear to be very few such weather stations. If I type Cambridge (the nearest UK city to me) I'm offered 17 Cambridges in the US and 2 in Canada.

Anyone outside the US should trial this app carefully before buying based on the glowing reviews here.

Sorry to hear you aren't finding any built-in locations near you. You can create a custom location if you know of a weather station nearby. I'm in the process of adding about 30,000 new locations to the next update, so definitely check back when that is available.

If you need help setting up a custom location, get in touch by selecting "Email Gaucho Software Support" from the Help menu in Seasonality Core.

The developer's website is poorly lacking in info/support on the app. There's no forum, for instance or solid breakdown of what the features are there. In case you were wondering what particle mode was, you can find it in the (non-searchable) help file. To save you the trouble, here's the info (the dev should really put on the website): Particle Mode is an overlay you won't find in any other app. Particle Mode shows what it would look like if you dropped thousands of particles on the surface of the earth and the wind blew them around. This overlay is best viewed while zoomed a bit further out than usual. Seasonality Core downloads the latest model wind data, so what you are seeing matches what is really happening around the world right now. Particles are colored by temperature, so in a quick glance you can see how the temperature changes in different regions. In the map settings, there is a slider where you can set how many particles are simulated (this ranges from around 10,000 to more than 200,000 particles). Choose fewer particles if you don't want to tax the processor of your Mac too much, or more if you want to see the best display possible. There is quite a bit of processing required to run this simulation (Seasonality Core needs to figure out the new position of every particle, 30 times a second). To keep Seasonality Core from using too much of your Mac's processor time, there is a checkbox in the Map settings to disable Particle Mode while the app is in the background.

I found Particle Mode to be entirely intuitive. The "particles" are different colors, obviously corresponding to temperature. They move around, which means "wind". Seasonality Core is the quintessential Mac app in it's intuitive GUI design. Even my mom, who has trouble with normal web browsing and cannot grasp features like Mission Control, could use Seasonality once I gave her a quick demonstration. She digs the particle mode and understood it without explanation - if she could, then anyone can. Seriously, if you can't figure it out, see a doctor for a brain checkup, because something is wrong. You can get a full list of features by going to the Seasonality Core page and paging down: http://getseasonality.com/core While there, check out the sneak peak at Seasonality Pro for iPad. I hope Seasonality Core will get the same features as Pro - otherwise the iPad version will slay the Mac version: Contour maps, gradient editors, and customizable multiple map layers. Sweet! The price is steep, considering free websites like Weather Underground. Still, it's so easy to use and utterly gorgeous, so for weather geeks it's probably worth it. I set it as a login item and keep it hidden in the background, so the weather is only a command-tab away. I set the auto refresh to once a day and manually refresh it when I need it. That way, it doesn't chew up bandwidth, but I get a complete weather graph history. For those with unlimited data connections, you can set it to refresh as often as every half hour.

Don't be a jerk.

Spare me the insulting drivel. Do you work for the developer of this "quintessential" Mac app with its "intuitive GUI design" or what?

Contrary to your assumptions, it's not always obvious what the particle mode was doing to everyone else including your dog unless they see the description I had to dig up at the time.

This is one of the most intuitive apps I've ever used. If you can't figure it out then that's YOUR problem, not the developer's.

Actually in the time you've spent whining about how hard the app is to use, you could have contacted the developer to have him hold your hand through the learning process. I've communicated with the developer about feature ideas and he's very open and helpful.
