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.
Wind and local conditions
Northeast monsoon 10–18 knots December–March; southwest lighter 8–12 knots. Squall lines can gust 30+ knots with rain in under an hour.

Conditions at a glance
What stood out in the forecast
Wind
Good8 kt · BF 3
Sustained to 8 kt · gusts to 18 kt · BF 5
Beaufort 5 — 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.
Rain
Fair63%
0.4 mm total · 63% peak chance · 3 wet hour(s)
Showers possible across 3 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
Poor32°C
Air 27–32°C · feels like 27–38°C
Feels-like 27–38°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
Good4.0 nm
Lowest 4.0 nm · best 8.5 nm today
Generally clear sightlines (about 7.4–8.5 nm). Good for spotting traffic and shoreline references — still verify charted marks; glare and spray can fool you even on “clear” days.
Barometric pressure
Good1009 hPa
1009 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
FairUV 7.8
High index — plan sun protection before you leave the dock. · peak near 13:00
UV 7.8 is elevated. Cloud cover does not block all UV — protect skin and eyes, especially on white decks and sails.
