Built for Northern Europe — Surflert continuously tracks your local and remote surf conditions and alerts you when they start to line up with your requirements. Surfing in Northern Europe is about timing. Surflert continuously evaluates surf conditions using YR forecast data, tuned specifically for Northern Europe. Instead of global averages, we focus on local detail — where missing the right hour means missing the session. Surflert keeps watch so you don’t have to and helps you catch the windows daily updates often miss. Whether you’re waiting for the kind of conditions that happen once a year, want to keep an eye on a remote spot, or aiming for more everyday sessions, Surflert adapts to how you surf. Features: Set your own conditions Create custom alerts based on wind, swell, direction, temperature, rain, daylight, days of the week, and time ranges. See all spots at a glance Open the app and quickly check the current status of your saved spots. Get smart push alerts Receive a heads-up when conditions start to line up, with an optional get-ready alert. Track your sessions Plan sessions and invite friends. Log them with ratings, photos and notes, while keeping a snapshot of the forecast from when each session was planned.
