📊 Data Points & Details

The detail screen behind every data point — graphs, sunrise and sunset quality, moon phase, air quality, pollen, tides, and the Area Forecast Discussion.

Every measurement Forecast Bar tracks has a full detail screen behind it — a graph or a purpose-built view, for any day in the forecast.

Opening the detail screen

There are three ways in from the main screen:

  1. Tap the current conditions card — opens today's temperature detail.
  2. Tap any data point tile in the tiles row — opens that data point.
  3. Tap an hour inside an expanded day in the daily forecast — opens the detail for that exact day and hour.

Tapping certain notifications (like a Beautiful Sunset alert) also lands you here.

The day selector

A strip of days runs across the top of the screen. Tap any day to see that day's version of the current data point — the graph, times, and values all update. The bottom grid updates too, so you can browse any data point for any forecast day.

The graph

Most data points display as a graph of the day's hourly values. Touch and drag across the graph to scrub — a readout follows your finger with the exact value and time for each hour.

Special detail views

A few data points get richer, purpose-built screens instead of a plain graph:

Sunrise & Sunset

Shows today's sun times along with a sunrise & sunset quality score — Forecast Bar's prediction of how colorful the sky will be. Tap the quality row to open the full quality forecast, with the color-potential score, the weather ingredients behind it, outcome odds, and a viewing plan. See Sunrise & Sunset Quality for how the score works and how to get notified about great ones.

Moonrise & Moonset

Shows moon times together with a realistic rendering of the current moon phase — the moon you see on screen matches the one in the sky.

Air Quality

The air quality index for your location, with category and pollutant details.

Pollen Count

Pollen levels for your location — handy on allergy mornings.

Tides

For coastal locations, a tide chart for the selected day, with:

  • the tide station name and its distance from your location,
  • high and low tide times, and
  • the water temperature, when a station nearby reports one (the reading can come from a neighboring reference station, which is named alongside the value).
The Sunrise & Sunset detail screen with the solar arc, sunrise and sunset times, sunset quality score, and the data point grid below.
The Sun detail — solar arc, first-to-last light, the sunset quality score, and the data point grid.

The all-data-points grid

Below the detail view is a grid of every data point available for the selected day. Tap any cell to switch the detail view to it. The grid is also customizable — press and drag cells to rearrange them (the "Drag to rearrange" hint at the bottom reminds you). Your order is remembered.

These are the 21 data points available on the main screen and in the grid:

Area Forecast Discussion

The Area Forecast Discussion sheet showing a National Weather Service discussion with key messages.
The Area Forecast Discussion — the forecaster's own reasoning, straight from your local NWS office.

Tap the document icon in the toolbar to read the Area Forecast Discussion (AFD) — the technical write-up National Weather Service forecasters publish alongside each forecast, explaining their reasoning: which weather models they trust today, where the uncertainty is, and what could change. It's the closest thing to reading the forecaster's mind.

The discussion is a US National Weather Service product, so it's available for US locations only. Use the share button in the sheet to send the full text anywhere.
