The weather as one scrollable, stock-chart-style line

A dark weather chart for Grand Falls-Windsor: a colour-graded temperature line rising and falling across four day and night bands, with record high and low labels, comfort and freezing reference lines, blue rain bars and moon phases along the top.

A weather site that skips the cards and draws the whole stretch as one temperature line you can zoom and scroll, like a stock chart, with the rain, the sun and what is normal for the date laid underneath.

The author built it for three plain questions: how cold did it get last night, when will it rain next after I put down fertilizer, and is today unusual for this time of year. Every site the author tried made them dig for the answers. Weatheristic puts them on one screen. Day and night are shaded bands, and the line is colour-graded from blue to orange.

One choice is deliberate and a little odd: the temperature axis does not rescale. It stays at roughly -4°F to 86°F (-20°C to 30°C) most of the time, so the height of the line tells you how warm it is before you read a number. A winter week sits low on the chart and a heat wave climbs it. If the graph looks off-centre, that is by design.

The Overlays menu adds the rest: the typical range for the date, record high and low for today (and a flag when today beats them), precipitation amount and chance, feels-like, dew point, wind, UV, humidity, sunrise and sunset, and comfort and freezing reference lines. Moon phases ride along the top. Units can be switched, a view can be shared as an image, and cities come from a search box or “Use my location.”

It is free, with no account, no ads and no cookies, and it is a static D3 page. Visits are counted with a self-hosted, cookieless Plausible.

The limits are stated by the author. Weather comes from Open-Meteo, and the records come from its reanalysis archive, which is modelled data rather than station readings, so daily extremes may be a bit off. The forecast looks 14 days ahead. It was built for one person’s own use, and the HN thread was a single friendly comment, so there is no outside verdict yet on how the format holds up for other people’s questions.
