SunLah: Singapore Weather
Weather, air quality & taxis
Free · Designed for iPad. Not verified for macOS.
Weather, UV, haze, taxis and live traffic for your Singapore trip - straight from Singapore's own open data. No account, no ads, no tracking.
SunLah is the simple weather and mobility companion for visitors to
Singapore. Whether you're planning a sunrise at Marina Bay, a hawker
hop, or a rainy-afternoon museum run - SunLah tells you what the next
few hours actually look like, where the haze is, and where to grab a
taxi.
Built directly on Singapore's own open data (data.gov.sg and LTA
DataMall), so the numbers you see are the same numbers the locals
follow.
WHAT'S INSIDE
• Right-now weather for your area. Singapore's NEA forecast areas
matched to your live location - Marina Bay reads different from
Changi, and we show the difference. Big temperature, current
condition, and the humidity so it isn't a surprise.
• Should-I-go-outside? score. One number that blends heat, rain, UV,
air quality, and wind into a clear "great day" / "okay" / "stay in"
call. Tuned for tropical conditions.
• Next-hours strip. Hourly outlook for the next few hours, with the
exact condition icon - rain coming in 90 minutes is hard to miss.
• 4-day outlook. The NEA's forecast in a clean row layout. Highs,
lows, and a glance at the trend.
• Air & haze advisory. PSI by region (north, south, east, west,
central) with health advice that escalates with the band - from
"all clear" to "stay indoors." Push alerts when the air turns.
• Carparks nearby. Live HDB carpark lots, distance from you, sorted
by availability.
• Live taxi map. Available taxis right now from LTA DataMall, on a
pinch-to-zoom map. Tap one to see the distance and open Maps with a
navigation pin.
• Live traffic cameras. Tap any LTA camera for a full-size snapshot,
a mini-map of where it is, and a "near {area}" label so you know
whether to bother heading that way.
• Push alerts you actually want. Rain in the next couple of hours,
high UV, or PSI entering the unhealthy range. Opt in per type from
Settings - no spam, no marketing pings.
• English + Tiếng Việt. Localised for English and Vietnamese, two of
Singapore's biggest visitor groups.
WHY WE BUILT IT
Tourists need fast, trustworthy answers - and Singapore's open-data
portal already has them. SunLah is a clean window onto that data, with
no ad trackers and no account required. We don't sell your location;
we use it once to find your forecast area.
