Residents, planners, researchers, and application developers can use it to locate hawker centres, assess access to affordable food, and build local discovery tools.
National Environment Agency GeoJSON of active dengue cluster polygon boundaries in Singapore, with metadata such as case count and locality. Public-health officers, town councils, and residents map current outbreak zones; see nea.gov.sg dengue clusters for the latest situational updates.
National Environment Agency monthly mean relative humidity (%) at Changi Climate Station from January 1982 through June 2026. Climate researchers, building engineers, and outdoor-event planners use the long Singapore humidity series for comfort, energy, and weather-risk analysis.
National Environment Agency CSV of the absolute monthly extreme minimum relative humidity recorded at Singapore's Changi Climate Station from 1982 through mid-2026. Each row gives the lowest daily minimum relative humidity (in percent) observed in a given month. Climate researchers and weather analysts use the long series to study dry-spell severity, humidity extremes, and long-run atmospheric trends.
This dataset records the monthly absolute extreme minimum of surface air temperature at Singapore’s Changi Climate Station. Each monthly value represents the lowest daily minimum temperature observed during that month, measured in degrees Celsius (°C). The metadata supports monthly time-based analysis and a specific geographic reference point at Changi, making the dataset relevant for examining unusually cool conditions, climate and weather patterns in Singapore, environmental monitoring, and comparisons of monthly temperature extremes. It can support research and search intents such as finding Singapore’s lowest recorded daily minimum temperature by month, analyzing cold-weather extremes at Changi, studying long-term temperature variability, and identifying monthly observations for climate-related reports or data visualizations. The provided metadata does not specify the available date range.
National Environment Agency monthly absolute extreme maximum surface air temperature—the highest daily maximum in each month—in degrees Celsius at the Changi Climate Station from January 1982 through June 2026. Heat-risk and climate analysts monitor peak monthly temperatures in Singapore.
National Environment Agency monthly mean daily minimum surface air temperature in degrees Celsius at the Changi Climate Station from 1982 through June 2026. Climate analysts track Singapore’s overnight temperature trends using the long official monthly series.
National Environment Agency monthly highest daily total rainfall in millimetres at the Changi Climate Station from January 1982 through June 2026. Hydrology and climate users monitor extreme daily rainfall intensity within each month in Singapore.
National Environment Agency monthly mean surface air temperature in degrees Celsius at the Changi Climate Station from January 1982 through June 2026. Climate researchers and the public track Singapore’s long-run monthly temperature averages in °C.
National Environment Agency monthly mean daily sunshine duration in hours at Changi Climate Station from January 1982 through June 2026. Climate researchers and planners use the long sunshine series for weather normals and outdoor activity planning in Singapore.
National Environment Agency monthly mean daily maximum surface air temperature (°C) at Changi Climate Station from January 1982 through June 2026. Climate researchers and weather analysts track long-run maximum-temperature trends in Singapore.
National Environment Agency monthly total rainfall in millimetres at Singapore’s Changi Climate Station, with coverage from January 1982 through June 2026. Climate researchers and weather analysts monitor long-run monthly precipitation at the national climate reference station. Columns cover month and total rainfall.
National Environment Agency monthly rainy-day counts at Changi Climate Station from 1982 through mid-2026, defining a rain day as 0.2 mm or more of rainfall. Climate and water-resource users track wet-day frequency for Singapore’s eastern reference station.
National Environment Agency CSV of hourly wet bulb temperature readings in degrees Celsius at Singapore’s Changi Climate Station from January 1982 through May 2025. Climate and heat-stress researchers use wet-bulb series to track humidity-adjusted temperature at the Changi reference site.
National Environment Agency CSV listing scheduled closure dates for hawker centres in Singapore across the four quarters of the year, together with periods set aside for other works. Each row covers one centre with quarterly cleaning start and end dates, remarks, address, latitude and longitude, the number of market and food stalls, a photo URL, operating status, and Google 3D view links. Diners use it to check whether a hawker centre is closed for spring cleaning before heading out, while developers build closure reminders and hawker directories on top of it. Researchers and GIS users map hawker centre locations and stall counts across towns for food-access analysis.
National Environment Agency GeoJSON of areas where NEA Gravitraps detected relatively higher Aedes aegypti mosquito populations from April to June 2019. Public-health officers, town councils, and residents map historical high-Aedes zones for dengue risk awareness and overlay them with housing and drainage layers.
*Beta dataset*
This is a new dataset; response fields, coverage start date, and behaviour may still change as we monitor reliability. Please reach out to [email protected] if you notice anything unexpected.
Real-time weather radar imagery from NEA. The weather radar transmits electromagnetic pulses that detect precipitation (rain, hail, snow) up to a few hundred kilometres away and estimates their intensity from the strength of the echoes. The data is updated every 5 minutes and covers a fixed range of 70 km, 240 km and 480 km, centred on Singapore.
The weather radar may occasionally pick up reflected signals from sources other than rain. These sometimes appear as stationary-coloured areas.
Each response includes geospatial metadata (projection + boundary box) and presigned PNG image URLs.
Rainfall intensity legend: the RGB/hex colour mapping for rainfall intensity is available in this dataset's API specification - download it from the "API Specification" section on this page to view the full legend table.
The data is updated every 5 to 15 minutes.
National Environment Agency hourly historical PM2.5 readings for Singapore, measured in micrograms per cubic metre and covering April 2014 through May 2026 across more than 105,000 rows. Each record gives a timestamp together with concurrent readings for the North, South, East, West, and Central regions, allowing fine-grained comparison of fine-particulate pollution across the island. Air-quality researchers, health analysts, and developers use the series to study haze episodes, daily pollution cycles, and long-run PM2.5 trends. The long, consistent hourly history also suits model training and dashboards that need continuous pollution data.
National Environment Agency historical CSV of Singapore’s regional 24-hour Pollutant Standards Index from April 2014 through May 2026. Columns cover North, South, East, West, and Central readings alongside the 24-hour PSI series. Environmental researchers and haze analysts reconstruct daily air-quality episodes across the island’s monitoring regions.
