Kitesurfing is better with people, and finding them shouldn't be the hard part. Spotties is the kite spot finder built for exactly that: check live conditions, see who's heading to the water, and show up already knowing who you'll be riding with. FIND YOUR SPOT Browse a growing map of kitesurf, kiteboard, and wingfoil spots worldwide, each with live wind conditions and photos from riders who've actually been there. See if a spot is kiteable right now, based on real wind direction and speed – not a generic forecast. KITEABLE, AT A GLANCE Every spot shows a simple kiteable indicator, built from live wind against that spot's ideal direction and range – set by local riders, not an algorithm. Know before you pack the van. FIND YOUR CREW Post that you're heading out and see who else is planning the same session. Set a time for a proper meetup, or keep it loose – either way, you'll know who's going to be there before you leave the house. RECAPS & BADGES Log your sessions with photos, mood, and who you rode with. Earn badges as you rack up spots and sessions. Your profile becomes a running log of your kite life, not just a feed to scroll. GUIDES FOR RIDERS Picking your first setup, sizing your kite, planning a trip – our guides are written by kiters who've actually done it, not optimized for search engines. NEW TO KITESURFING? Filter for beginner-friendly riders, ask questions before you show up, and find someone to show you the ropes at your first spot. TRAVELING WITH YOUR KITE Heading somewhere new? Spotties covers spots across Europe, North Africa, and beyond, with local conditions and local riders at each one. Land in a new country and still know where to go and who's out there. SAFE AND WELCOMING Every rider has a profile, and reporting and blocking are built into every corner of the app – reviews, photos, sessions, and chats. It's how the community stays what it should be. Spotties turns a wind forecast into a plan: where to go, what it's like when you get there, and who you're kiting with. Core features free to use.
