The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
Our own model
Our own forecast engine — not a third-party widget. It weighs these water factors into one go-or-stay verdict for this coast; the 0–10 dial is that verdict, read out as a number.
Safety gates
It all folds into a single 0–10 score and one verdict: go or stay.
A forecast, not a guarantee — the sea has the last word.
Where to get in, where to hunt
Wind, wave and the swell windows — when to go and the best hours.
The day is picked above, in the hero. Here are that day's windows, the hour-by-hour map and the trends. Tap a window to break down the conditions.
Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
spearo.app folds wind, wave, swell period, visibility, tides, water temperature and risk into a single verdict — go to the spot or not. It computes 7 days ahead from open marine models (Open-Meteo, IPMA), with no sign-up and no accounts. Built for solo spearfishing off the rocks, where any mistake costs dearly.
Now live: 1152 spots across 189 stretches of coast — mainland Portugal, Madeira and the Azores.

The models set the window. Whether you go in is read only at the water: count the sets, watch the surge on the entry. If in doubt, you don't get in.
Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.

Google MapsSOLO is the biggest risk: underwater you can black out from lack of oxygen silently and fatally, with no one around. Solo is never truly «safe». Below are the best weather windows; carry a buoy, tell someone your plan and exit time, and any doubt — don't go.
Cameras, map and reference — to hand as you come up.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».
Rules change and the seasonal bathing-zone closures are set yearly by Transport Malta. Before heading out, check with the Department of Fisheries & Aquaculture (servizz.gov.mt) and the current notice to mariners; stay well clear of buoyed bathing areas.
Spearfishing in Sliema is mostly a legal-space problem, not a remote-reef hunt. The listed marks are all convenient urban shore reefs: Exiles Reef, Fortizza Reef, Coral Gardens and Qui Si Sana. That convenience is exactly the risk. Exiles and Qui Si Sana explicitly carry swimmer-zone warnings, and the whole Sliema front is exposed to heavy bathing use when Transport Malta's annual designated-zone notices are in force. Malta requires no recreational licence for shore or breath-hold spearfishing. Scuba and night spearfishing are banned, designated bathing zones must be avoided, ċerna should be released, and bluefin tuna is special-authorisation only.
The Sliema marks are easy to reach and easy to misuse. They sit along an urban waterfront with lidos, swimmers, storms that affect visibility, and annual bathing-zone closures. No formal safety rating is supplied, so the table stays with the actual habitat notes: shallow or mid-depth reef, low wall, overhangs, gorgonians and urban entry. For Sliema, the first question is often not whether there are fish, but whether the water is outside the current swimmer closure and clear of bathers.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Exiles Reef | Urban shore reef off Exiles rocks | To 15 m | Urban reef, swimmer-zone caution | Exiles rocks | Bream and octopus are listed. Summer bathing zones and swimmers are the main constraint. |
| Fortizza Reef | Reef and low wall along the Sliema front | To 14 m | Convenient shore dive, weather-sensitive viz | Sliema seafront | The note calls it convenient from shore, with moderate visibility after storms. Do not read convenience as legal clearance near bathers. |
| Coral Gardens | Rocky reef with gorgonians and overhangs | To 16 m | Urban entry with structure | Sliema urban shore | Bream, wrasse and cuttlefish are listed. The structure is useful, but the shore is still urban and exposed to swimmers and boats. |
| Qui Si Sana | Shallow reef off the lido | To 8 m | Training ground only outside swimmer zones | Qui Si Sana lido area | The local note calls it an easy training ground, best outside the summer swimmer zone. That caveat is the whole point. |
Do not reduce Sliema to a simple 100 m shortcut. Transport Malta closes designated swimmer and bathing zones to spearfishing by annual notice, roughly for the summer season into mid-October. Sliema is exactly where that bites: Exiles, Qui Si Sana and the seafront lidos draw swimmers into the same shallow reef band. Check the current notice to mariners, stay outside buoyed bathing areas, and move away if the entry is active with swimmers.
The Sliema spot notes name bream, octopus, wrasse and cuttlefish. The national Malta list also includes sargu, awrata, dentici and lampuka. Ċerna, dusky grouper, is a species of national concern and release is advised; it should not be treated as a normal urban trophy. Bluefin tuna is not a casual pelagic bonus either: it may be taken only with special authorisation under the relevant quota regime.
No best month is supplied for Sliema. The practical season is controlled by two forces: urban bathing notices and east-facing exposure. The physics record points to an east or north-east problem sector, and Fortizza is described as having only moderate visibility after storms. In the busiest bathing period, the easier the entry looks, the more likely it is to be inside or next to a designated swimmer zone.
No recreational licence is required for shore or breath-hold spearfishing in Malta. The restrictions are behavioural and spatial. Spearfishing with scuba or an aqualung is banned, and night spearfishing is banned. Protected species such as fan mussel, date mussel, seahorses, loggerhead turtle and monk seal must not be taken or disturbed. Transport Malta's annual swimmer-zone notices decide which bathing areas are off-limits for the season.
The listed shore marks are Exiles Reef, Fortizza Reef, Coral Gardens and Qui Si Sana, all subject to urban swimmers, bathing-zone notices and sea state.
Do not rely on a simple distance shortcut. Stay out of designated or buoyed bathing zones closed by Transport Malta's annual notices and avoid active swimmer areas.
Bream, octopus, wrasse and cuttlefish are listed locally. Ċerna, dusky grouper, should be released, and bluefin tuna needs special authorisation.
No month is specified. Choose by current bathing-zone notice, swimmer pressure, storms and east or north-east exposure.
No. Shore and breath-hold spearfishing do not require a recreational licence in Malta or Gozo.
No. Spearfishing with scuba or an aqualung is banned.
No. Night spearfishing is banned.
Use the current Transport Malta notice and buoyed bathing areas as the control. Annual designated swimmer-zone closures are off-limits during the notified season.
