NEA exposes realtime weather open data through APIs for air temperature, rainfall, relative humidity, wind direction, and wind speed across Singapore’s station network. Readings can arrive at up to one-minute intervals at individual weather-station granularity, supporting dashboards, apps, and research needing fresh conditions. The collection bundles five API datasets alongside coverage from December 2016 onward. Developers integrate NEA feeds for outdoor event safety, urban microclimate monitoring, and public information services.
Official description
NEA provides APIs for readings of temperature, humidity, precipitation and wind conditions at up to one-minute intervals. The data is provided at weather-station level.
National Environment Agency API providing wind-direction observations from automated weather stations across Singapore from 29 November 2016 onward. Values are available at one-minute resolution, updated every five minutes, and represent mean wind over a ten-minute period. Weather applications and researchers can monitor local wind patterns by station, but should account for possible technical gaps, later corrections, and site-specific obstructions that may influence readings.
This API provides minute-by-minute air-temperature observations from automated weather stations across Singapore, with records available from May 2016. It is suited to monitoring short-term weather conditions, comparing station-level temperatures, and supporting operational or research applications that need high-frequency readings. Values are published automatically and may contain gaps or later corrections, while local siting conditions—including coastal exposure—can influence how well an individual station represents broader conditions.
National Environment Agency API providing minute-level relative humidity readings from weather stations across Singapore, refreshed every five minutes from November 2016 onward. Records may have gaps or later corrections because they are automatically generated. Developers and weather analysts use the station observations for near-real-time monitoring and local-condition applications.
National Environment Agency API providing precipitation readings at weather-station level across Singapore, updated every five minutes with coverage from December 2016 onward. Readings come from automated weather instruments and are published as soon as they are generated, so occasional gaps can occur and values may be corrected later. Developers building weather apps, flood-monitoring dashboards, and climate researchers use the feed for near-real-time rainfall by station, noting that local siting conditions can influence individual readings.
National Environment Agency API feed of wind speed readings from automated weather stations across Singapore, available at one-minute resolution and refreshed every five minutes with coverage from December 2016. Values represent mean wind over a ten-minute period at station level and are published automatically as the instruments generate them, so occasional gaps and later corrections are possible. Developers build live weather dashboards, sailing and outdoor-activity apps, and environmental monitoring tools on the feed. Researchers combine it with rainfall, temperature, and air-quality stations to study microclimate and local wind patterns, bearing in mind that readings can be influenced by nearby obstructions.
