Every spot page carries live conditions pulled from Open-Meteo — no account needed to look. At the top you get a conditions-right-now snapshot (water temperature, air, wind, and waves) plus an overall good / fair / poor rating, so you can size up a spot at a glance before committing to the drive. Open any spot from the map or the A–Z directory to see it.
Four readings do most of the work. Water temperature drives your wetsuit choice and your cold-shock risk — it's the number to respect most. Wind tells you how choppy it'll be and how much you'll drift. Waves and swell matter on the sea. Visibility hints at how murky the day will be. One caveat: lakes and rivers have no marine data, so their water temperature is shown as an estimate from air temperature and labelled as such — treat it as a rough guide, and trust a recent conditions report from another swimmer (or your own thermometer) over it.
The rating is a quick gut-check, not gospel. For sea and ocean spots it weighs waves and wind together — calm with small waves is good, big waves or strong wind is poor. For lakes and rivers it's wind-driven. It tells you whether conditions are pleasant, not whether they're safe for you: a "good" rating in February still means genuinely cold water, and your own experience always overrides the colour.
To plan ahead, open the forecast: the hourly table (roughly 6am to 8pm) and the day tabs let you pick the calmest morning, check which way the wind is blowing, and watch the temperature trend across the week. The full multi-day forecast is part of Pro; free members get the current day's detail. Use it to choose *when* to swim, not just where — a spot that's rough at 4pm is often glass at 7am.
Forecasts and crowdsourced reports answer different questions, so use both. The forecast predicts wind, waves, and air; a recent conditions report from another swimmer tells you the actual water temperature, clarity, and how busy it was. The habit worth building: glance at the rating and wind the evening before, then confirm the water temperature the morning of. Tell someone your plan and read the safety basics before you go — the data informs the decision, it doesn't make it for you.
