All the essentials, and then some

Seasonality Go puts an advanced weather tracking and analysis engine on your iPhone or iPad, and it is all touch-based to boot, for simplicity.

Our back-end collects and processes data from around the globe, from the basics, such as current conditions and forecasts, to advanced parameters such as wind velocity, cloud cover, pressure, snowfall, wave height and more.

Data is presented as meaningful graphs, whose design and color palette have been optimized for legibility, even in challenging conditions.

Seasonality Go can download up to four days worth of past data, and saves up to two weeks of continuous data on your device. This makes it easy to work on your weather journal or to perform calculations of your own.

Weather the way you want it

Our exclusive modular interface in the iPad version allows you to create as many dashboards as you wish to track the data you want.

You can create an infinity of screens, each displaying a particular set of data for a location. For example, you can have a screen for your home and another for your beach house. Or you could create a screen for work days and another for your surf outings.

Use intuitive gestures to interact with the data: pinch and zoom to adjust timelines, double tap to reset and access advanced tools, drag to resize modules as you compose and edit your personal screens.

Seasonality Go is usable right from the start, and you can learn expert features as you go. There’s no learning curve, and the application comes with sane defaults for immediate benefits.

Your international pad of mystery

Seasonality Go knows no boundaries. The application comes bundled with over 30,000 locations in over 200 countries worldwide for one-tap access.

If you can’t place yourself on the map, our live tracking feature taps the power of the geolocation capabilities in iOS to locate you and refresh the screen as you move.

Thanks to our custom back-end, which has been extensively tested since 2004, we gather, process and track data from around the world.

Some advanced features may not be available worldwide just yet but we’ve got you covered with the basics wherever you go. We are also working hard on expanding our coverage, for all our users.

Data from the best of sources

While weather data is now available from a wide range of sources, not all tools are equally accurate or reliable.

This is why we continuously poll the best possible sources, including the National Weather Service in the United States and similar scientific institutions around the globe. Our own back-end then compiles and prepares the data for broadcast.

Because Seasonality offers full details, such as maps, graphs and numerical data, you can delve deep into the information from many angles and understand how it may affect your planned activities.

Seasonality Go relies on independent and non-commercial scientific sources for its data which guarantees balanced, complete and continuous reporting.

Love us for your money

$5.99 gets you today’s most intuitive and advanced weather application for the iPhone and iPad, as well as access to our famed back-end that downloads and crunches data from all around the world for comprehensive reporting, at no extra cost.

Unlike subsidized alternatives Seasonality Go provides ad-free, subscription free access to your data. That means no nags and no recurring costs.

Our exclusive interface replaces many extra gadgets and services, making Seasonality your one-stop source for weather data in the long run, be it at home or on-the-go.

Because Seasonality’s data comes from state-operated and research operations, there are no risks of our sources going dark or charging for the content on a whim.

International availability

Seasonality Go uses information from reliable sources such as national weather bureaus and research groups. While we strive to offer relevant information in every part of the world, some data can be a bit difficult to come by, which is why some features are currently unavailable outside of the United States, Puerto Rico and Guam.

The table below explains what is currently available to you depending on your region of the world. Please rest assured we are hard at work expanding our international coverage. Seasonality Go users start benefiting from new data sets automatically as they go live in our back-end: no paid updates or manual actions are required, so keep a close watch on these graphs!

Numerical Data United States International
7 Day Forecast Sourced from the National Weather Service. The continental U.S. is forecasted using a 5km grid, 6km for Alaska, 2.5km for Hawaii and Guam, and 1.25km for Puerto Rico and the Virgin Islands. Sourced from a 0.5 degree GFS model output. In middle latitudes, this results in approximately a 45km-grid.
Hourly Forecast Sourced from the National Weather Service. Most data is plotted every 3 hours, although some data, like precipitation amounts, is plotted every 6 hours. Sourced from a 0.5 degree GFS model output. All data is plotted every 3 hours.
Current Conditions Sourced from the National Weather Service METAR data. Sourced from the National Weather Service METAR data.
Astronomical Data Computed locally and therefore fully available. Computed locally and therefore fully available.
Radar Imagery Base reflectivity radar imagery covers most of the US. Base reflectivity available over much of Australia and Canada. Radar is not yet available outside these countries, but we are working on the matter.
Satellite Imagery Full coverage. Full coverage, except for latitudes beyond 80 degrees North and South because geostationary satellites cannot see the poles.
Surface Analysis Full coverage. Available over most of North America and surrounding oceans. Not available elsewhere.
Graphs United States International
Temperature Full coverage for past and future. The forecast is plotted every 3 hours out to 72 hours, then every 6 hours after that. Full coverage for past and future. The forecast is plotted every 3 hours.
Wind
Cloud Cover
Humidity
Pressure Full coverage for past observations, but the forecast is not yet available. Full coverage for past observations, but the forecast is not yet available.
Probability of Precipitation Past coverage not applicable. The forecast is plotted every 3 hours out to 72 hours, then every 6 hours after that. Past coverage not applicable. The forecast is plotted every 3 hours.
Liquid Precipitation Past observations are covered at many but not all weather stations. The forecast is plotted every 6 hours out to 72 hours. Past observations are covered at very few weather stations. The forecast is plotted every 3 hours for the full forecast period.
Snowfall Past observations are not yet available. The forecast is plotted every 6 hours out to 48 hours. Past observations are not yet available. The forecast is plotted every 3 hours for the full forecast period.
Wave Height Past observations are not yet available. The forecast is plotted every 6 hours out to 120 hours with full coverage along the Pacific and Atlantic coasts and the Great Lakes. The location must be over water for the graph to work. Coverage is not yet available, but we are working on the matter.
