About Flowx

It was seven days prior to the 15th of December 2006 and I was checking out the weather for our wedding day. Was it going to be sunny or rainy? We didn't have a rainy day venue sorted. The forecast seven days out said it was going to be sunny. I checked it everyday right up to the 15th and fortunately, we didn't need a rain venue. Knowledge is power. Stress relieved.

A few years later, I thought with some swiping goodness this would be a super useful app for planning anything around the weather. And in late 2012 WeatherBomb was released. Check out my first YouTube release video (cringe!). We have come a long way since.

For many years WeatherBomb was a side project, literally out of an Auckland workshop. The change came in 2016 when we (myself, Sally and our boys Niva and Varo) moved to the tropical island of Rarotonga. We decided to turn WeatherBomb into Flowx and make it our livelihood. After a year+ of sprucing up the app we've released an app we're proud of. Much of the pride and anticipation is in the code which is designed for some cool stuff in the near future.

Cheers, Duane.

The Team

Duane Malcolm

Duane writes the code and answers emails. Many users think Duane is a Meteorologist and makes those wrong weather predictions but the truth is that he's just the messenger. Really, he's an engineer who likes to dream a lot and make cool things.

Sally Malcolm

Sally is a super organiser - she dots the i's and crosses the t's for Duane. It took some convincing but Sally has taken on the marketing effort and has the final say on design and color decisions. This is good since these were well neglected and is the missing piece to an Apple version of Flowx.

And Finally...

A big THANKS to the users and supporters who have helped out over the years. It has been enjoyable meeting many real people.

Data Sources

A special thanks to the organisations that provide the open-access to weather data.


National Oceanic and Atmospheric Administration (NOAA) provides the Global Forecast System (GFS) and the Wave Watch III (NWW3) forecast data.

Environment Canada

The Canadian Meteorological Center (CMC) provides the Global Deterministic Forecast System (GDPS) forecast data.


Made with Natural Earth. These are the beautiful terrain maps you see when you zoom right out.

OpenStreetMap is a map of the world, created by people like you and free to use under an open license.

Stamen make some great maps and visualizations. I especially like the waterpaint maps but unfortunately I couldn't get them to work in Flowx. I think Stamen Design is good example of a company that bridges between business and public-good.

Mapbox is a mapping platform for developers. They provide some the beautiful maps in Flowx, including the Pirate maps ;-).
