  @ivo Hi I'm sure you've heard from lots of surfers since this post went up, but I got here because I was looking for more options on viewing swell in Windy. I use Windy for general weather/wind, but so far cannot use it for waves because it does not offer some visualizations that are important for us. @jrbidlot 's post below is a great explanation of the various parameters that are important for ocean waves. Since I don't know ECMWF website as well though, I'll link to some pages from NOAA Wavewatch. For surfers, we rarely analyze one single parameter. They all are important. But two that are missing from Windy are the option to show primary and secondary swell periods (vs. showing mean period). As you can see below, this shows the timing of different swell events nicely, and swell period is important too since energy scales so much with period in shallow water. Different swell periods/directions will "work" for different breaks. See: https://polar.ncep.noaa.gov/waves/viewer.shtml?-multi_1-latest-pacific-tp_sw1- Also, note the arrows for direction, these are also quite useful for significant wave height display. https://polar.ncep.noaa.gov/waves/viewer.shtml?-multi_1-latest-pacific-hs- Thanks again for all your work on Windy, it's very useful for local wind prediction, which is also super important to surfers!

  More info on the unusual bulge on the centreline of the hull: https://thespinoff.co.nz/sports/06-09-2019/launching-the-whale-at-the-unveiling-of-americas-cup-boat-te-aihe/ @thespinoff.co.nz said: Most surprising of all is a sort of bulge running the length of the bilge, a bilge bulge, like an undercarriage... Being a lot heavier than the catamarans of the previous America’s Cup, it’s a harder boat to get onto its foils. So – as I understand it – the dolphin belly serves as a kind of smaller, secondary hull, minimising drag in that awkward phase between foiling and not foiling. During those not-slow, not-fast times, “it’ll only be that bit in the water, and that part is far more like a multihull shape”, said designer Dan Bernasconi...

  @HelsinkiKhan Hi, thank you for your message, but the application is automatically open in wind layer. The reason is that we want to keep the app as fast as possible. And the wind layer is catched in our service. Please follow up this link https://community.windy.com/topic/9422/how-to-change-default-start-up-layer-on-windy

  @OcchioMeteo005 Thunder is produced by the explosive expansion of heated air surrounding a lightning channel. Thunder can be heard from a maximum distance of about 10 miles (16 km) under good atmospheric conditions. When lightning strikes close, thunder has a loud clap or snapping sound. The rumbling we hear is the sound of thunder reaching us at different times from the sound produced along its length. From: http://lightningsafety.com/nlsi_info/thunder2.html

  Technical issues happen once in a while. Even for billion dollar companies like Facebook or Google. Give some respect for Windy team that provide you free weather data from paid providers.

  @ingojons Sure, but Windy visualizes only weather models data and these models are not able to draw the fronts. They are drawn usually by meteorologists so you can’t find them on Windy.
