The sea at Praia do Boldro
Sea stateSea state: slight
The waves you may find
- Most commonMost common2.0 ft
- Significant4.0 ft
- Highest expectedHighest8.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.2 ft. Before heading out, expect waves of up to 8.2 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces northwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Saturday 31: 5.5 ft with a period of 10 s, from the east-southeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Surf in Praia do Boldro today
Surf today
Poor- 1.5–2.3 ft surf at the shore, a fun size for most surfers
- 1.6 ft swell at 8 s from the north, a bit short
- Moderate offshore wind (17 mph): it holds up and grooms the waves
- Rising tide (high tide at 6:35 pm)
- Light: First light 5:25 am · sunrise 5:46 am · sunset 6:01 pm · last light 6:22 pm
- Tide: low 12:05 am (-0.4 ft), high 6:15 am (6.9 ft), low 12:20 pm (-0.0 ft) and high 6:35 pm (7.1 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 80.8 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 40 kJ · Low power
Today’s surf at a glance
The best window, 5:00 pm to 6:00 pm, has light offshore wind. 7:00 am to 11:00 am can also work, with light offshore wind, though with a short-period swell.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in Praia do Boldro today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (12:20 pm): little current from 12:00 pm to 12:40 pm

- Moderate offshore wind (16 mph): it pushes surface swimmers away from shore
- 1.5 mph current toward the west, strong (model)
- Sun high: more light underwater
- Slack water today: low tide 12:05 am (11:40 pm–12:30 am), high tide 6:15 am (5:50–6:40 am), low tide 12:20 pm (12:00–12:40 pm) and high tide 6:35 pm (6:10–7:00 pm)
- Likely visibility: good. Swell (up to 2.5 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 80.8 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:22 pm. Waning gibbous (92%), rising at 8:34 pm: a bright night.
Your diving day at a glance
The best window, 11:20 am to 1:20 pm, combines slack water at low tide and the sun high, though with moderate wind and current. Also worth a look from 5:50 am to 7:00 am, with slack water at high tide, though with moderate wind and current.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.

Moon phase and position
Today the moon is 226,437 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 12:37–2:37 am Major · the moon passes overhead · high activity
- 1:09–3:09 pm Major · the moon passes underfoot · high activity
- 7:14–8:14 am Minor · moonset · medium activity
- 8:04–9:04 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.6 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow near shore: you only reach 33 ft at 0.65 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
