About sailing in Singapore Strait
The Singapore Strait is one of the busiest shipping lanes on the planet, linking the Strait of Malacca with the South China Sea. Recreational sailing centres on clubs and marinas such as Changi, Keppel Bay, Raffles Marina and ONE°15 at Sentosa Cove, with day sails to the Southern Islands or toward Pulau Ubin. Warm water all year and generally light winds make it a tropical — if traffic-heavy — sailing ground.
Best time to sail
Singapore can be sailed year-round. The north-east monsoon, roughly December to March, brings the most reliable breeze. The inter-monsoon periods have light, variable winds and frequent afternoon thunderstorms.
Sailing notes
Keep well clear of the shipping lanes and anchorages — hundreds of large vessels move through every day. Follow Maritime and Port Authority rules for recreational craft and restricted areas. Squalls known as Sumatras can sweep in with violent gusts, usually before dawn or in the morning during the south-west monsoon.
Singapore Strait wind and sailing weather
Winds are generally light, often under 10 knots, with the north-east monsoon providing steadier 10–15 knot breezes. Thunderstorms can bring sudden gusts of 30 knots or more and torrential rain. Tidal streams in the strait are strong. Check today's score before leaving the marina.

Conditions at a glance
What stood out in the forecast
Wind
Good9 kt · BF 3
Sustained to 9 kt · gusts to 16 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
Good0.0 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
Poor66%
2.4 mm total · 66% peak chance · 2 wet hour(s)
2 hour(s) with meaningful rain risk — expect reduced visibility, saturated decks, and slower reaction times. Full waterproof layers and clear eyewear help; consider delaying if comfort and sightlines matter for your route.
Air temperature
Fair30°C
Air 28–30°C · feels like 28–34°C
Feels-like 28–34°C once wind and humidity count. Layer so you can cool off in sun and warm up when wet; shivering crews make poor decisions.
Visibility
Fair1.1 nm
Lowest 1.1 nm · best 5.4 nm today
Visibility may dip to 1.1 nm even if the best part of the day reaches 5.4 nm. Haze, rain, or low cloud can hide buoys until you are close — brief the crew on what to watch for.
Barometric pressure
Good1014 hPa
1014 hPa → steady (2 hPa change)
Pressure is steady — no strong synoptic system pushing through on this snapshot. Local wind, sea breeze, and geography still dominate near shore.
UV / sun
PoorUV 10.7
Very high index — limit bare-skin time on deck. · peak near 13:00
UV 10.7 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.
