One glance tells you the plan: a window worth diving today, or a solid reason to wait.
Spearo reads the marine forecast for the Portuguese and Spanish coasts and folds swell, period, wind, visibility and tide into a single go/no-go call for solo spearfishing and freediving.
GO — conditions are in your favour
CAUTION — on the edge; make the call on the spot
NO-GO — better to wait
No tables to decode. The verdict is the loudest thing on the screen, anchored to the right day, with the best time window and a 0–5 star rating for how the fish should be moving. Everything else stays to the point: swell, period, wind and gusts, visibility and the tide.
This is guidance, not a safety device — and never a promise. The sea has the final say. Always check the real conditions on site, respect the local rules, dive within your limits, and never dive alone without proper training and backup. The final call is always yours.
WHAT YOU GET
• Go/no-go verdict with the best window and a star rating — one clear answer, not a wall of numbers
• 7-day outlook — see at a glance where the week's windows open
• Day detail — the numbers that matter for each day: wave height, swell period, wind with gusts, underwater visibility, tide (rising/falling, spring/neap)
• Official rough-sea warnings surfaced right on the forecast
• Species in season — minimum legal sizes, seasons and protected species so you fish inside the rules
• Entry-point spots — dive-in points ranked with a solo-risk read for how exposed each one is
• A real MapKit map — no-take / restricted zones drawn honestly; drop and save up to 5 of your own points, coordinates stay on your device
• Home-screen widgets — the week and the verdict without opening the app
• Go/no-go notifications — a heads-up when a green window opens for a spot you watch
• Works on your last cached forecast — with honest labels (live / cached-with-age / sample), never a fake
HELPS YOU FISH RIGHT
Spearfishing is a regulated sport. Spearo shows official no-take and restricted zones, minimum legal sizes, seasons and protected species so you can stay inside the rules — it never encourages breaking them.
WHO IT'S FOR
For spearos and freedivers who value a cool head: a verdict at a glance instead of guesswork, a clean read instead of noise. Dark, tactical design — legible in full sun and in a single look. Available in English, Portuguese and Russian.
HONESTLY
Spearo doesn't replace common sense, a dive buddy, or your own read of the water. It's a planning aid that saves time and helps you skip a clearly bad day. The forecast is built on open marine and weather data and refreshes through the day; we label what's live, cached or a sample. Coverage today is the coasts of Portugal and Spain, and it grows on the server — new spots appear without an app update. The final call — and the responsibility — are always yours.
Spearo is the companion app to spearo.app. Free. We only dive our own windows.
