About sailing in Singapore Strait

Singapore Strait is one of the world's busiest shipping lanes—recreational sailing clusters at RSYC and Sentosa with passages toward Pulau Ubin and southern islands. Traffic separation schemes dominate planning.

Best time to sail

December through March for northeast monsoon cleaner air; inter-monsoon April and October have thunderstorms. Southwest monsoon summer is hot with variable afternoon cells. Weekdays are usually quieter than weekends.

Sailing notes

Cross TSS only at designated angles with AIS on. Squalls from Sumatra line up on radar fast. Lightning risk ends many afternoon sails in equatorial season.

Conditions at a glance

What stood out in the forecast

Wind

Good

11 kt · BF 4

Sustained to 11 kt · gusts to 15 kt · BF 4

Beaufort 4 — a workable breeze for most day sails. Watch for funneling between headlands and tall buildings near harbors; local gusts can exceed the open-water forecast.

Seas

Good

0.0 m

Significant wave height 0.0 m

Relatively modest seas today (swell ~0.0 m). Still evaluate harbor entrance and wind against any tidal stream using local pilot notes.

Rain

Fair

20%

0.3 mm total · 20% peak chance · 2 wet hour(s)

Showers possible across 2 hour(s). Light rain is manageable with good gear; heavy bursts can obscure marks and other traffic — keep a hand on the plotter or chart.

Air temperature

Poor

33°C

Air 28–33°C · feels like 28–39°C

Feels-like 28–39°C with spray — dress for immersion, not the marina thermometer. Cold shock and hypothermia are real risks if someone goes overboard; carry spare layers in a dry bag.

Visibility

Good

2.7 nm

Lowest 2.7 nm · best 5.4 nm today

Generally clear sightlines (about 5.0–5.4 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.

Barometric pressure

Good

1010 hPa

1010 hPa → steady

Pressure is steady — no strong synoptic system pushing through on this snapshot. Local wind, sea breeze, and geography still dominate near shore.

UV / sun

Poor

UV 8.2

Very high index — limit bare-skin time on deck. · peak near 13:00

UV 8.2 is very high — water reflection adds exposure you do not feel on land. Broad-spectrum SPF, hat, lip protection, and hydration reduce fatigue; consider shade breaks if you are out all day.
