Personalized surf forecasting® – BUIO App

BUI0 is the cutting edge personalized surf forecast® delivered via FREE APP for iPhone and Android since 2017.

While nowadays surf forecasts are usually based on generalizations made by human forecasters, BUIO App is a Smart Surf Log. The free custom surf forecasting tool is developed in San Diego, CA and works worldwide.

BUIO App’s backend is based on machine learning and merges the functionality of a classic surf  journal with current swell and weather data from buoys and weather reporting systems into a custom surf forecast.

The stunning result is BUIO App’s personalized surf forecast®, a Smart Surf Log, which becomes more accurate while its user is logging more sessions.

Smart Surf Log

With a growing database of surf sessions and surf checks logged, BUIO App learns what the user prefers and makes recommendations based on previous experiences in the form of an individualized surf forecast, or as we’d like to say, it gives you #YourBestBet.

By processing the swell and weather data together with the users personal ratings of each surf session or surf check, BUIO App is trained what type of conditions the user prefers at a certain spot. Safe to say, BUIO App is a smart surf log.

If you go on a surf trip or move away, start logging your sessions and surf checks form day one. You get to choose how far you would like to drive via the “Distance”-option  in your live forecast. As off now, BUIO App only has limited functionality in parts of the world, where swell data isn’t available comprehensively.

+ You don’t have to spend any money on downloading and using the app.

+ A personalized surf forecast is tailored to your preferences in surfing.

It automatically acknowledges your skill level, the wave size you are comfortable in and the boards you ride. You don’t have to enter this information, your BUIO App learns what you enjoy.

Thanks to BUiO, i’ve been able to score some of my favorite spots practically empty. Being able to rate sessions based on my experience and preferences according to the conditions AND get notifications of predicted conditions according to my preferences is so much more helpful compared to what  other surf forecasting sites say.

Finally! A way that I can easily log my sessions. The more sessions I log, the better my personalized forecasting gets. I especially like the ocean topography map to understand how the waves at my favorite spots work. This app has really increased my knowledge about surf forecasting! Highly recommended.

This app is great for applying machine learning to your local surf spot and surfing preferences. Allowing for user input really gives it the weight to out-compete other standard prediction apps.

I used to log in my sessions on a notebook where I would write down the spot name, date, swell conditions, wind tide and so on, but I would often forget the exact conditions and it was hard to use it for anything else. This app is way better. It is easier to annotate the sessions and it retrieves the exact swell conditions for the date and time of your surf. The best part it is that it learns what you like,  (although it takes three or four logged sessions to start working) and recommends to you what spot is more likely to give you the surf you want. A nice feature is that you can share your session with contacts (without giving away secret spots) and make them jealous or let them know when they are missing good waves. 100% recommended.

Great App! It works. I love that it is customized to what YOU like. Epic surfing on Surfline might be too big for you and it is not really site-specific either.
