Skywater compresses hourly weather-station history into a compact, browser-native “time tissue”. Scrub years, replay extreme events, and compare cities — without dashboards, APIs, or map servers.
see1m.com is a research preview from Hold2X. No login. No install.
Tip: Auckland is larger because it includes more stations plus a small coastal inset (Browns Bay). NYC is lighter but still spans 20+ years of hourly history.
Maritime climate with sharp coastal gradients. Great for demonstrating dryness ↔ rain transitions and flood “pop”.
▶ Open Auckland viewerShows many “unnamed but huge” hydrologic events that rarely have a public narrative — and that’s the point.
▶ Open NYC viewerA short-range prototype demonstrating that the same pipeline and viewer can be stood up quickly for new regions.
▶ Open London demoSkywater is designed to render long time-series data directly in the browser, without spatial preprocessing workflows, map servers, or heavyweight toolchains. Alignment is intrinsic to the encoding — allowing fast deployment across cities, including environments where traditional pipelines are impractical.
Skywater is a lens for exploring historical station behaviour. It does not forecast, interpolate, or claim ownership of source data.
Browns Bay — rainfall-driven stream response (timelapse)
Dynamic coastal layers (intertidal study)
Two quick visual studies using the same spatial frame: rainfall drives stream response (with lag), and coastal layers provide context for how water behaves at the edge.
