This page intends to give some explanations to how features displayed in the homepage of Breezy Weather work and how they should be interpreted. Position of elements are described for a LtR display.
Homepage shows the weather for the selected location. When talking about current weather below, we will talk about current weather at the time of refresh.
In the background, you can see an animation matching the current weather condition. This animation is dynamic by default, but you can choose a static one in the settings (Appearance).
On top, you have city name of the location on the left, and location list and settings buttons on the right. You also have an Edit button that lets you access different options specific to the location, such as:
- Reorganize main screen (applies to all locations)
- (Current location only) Change location service
- Change main weather source or secondary weather sources (air quality, allergens, precipitations minute by minute, alerts)
- Change source-specific preferences
Just below, you can see the last time of refresh.
Above cards, you have details about current weather:
- Temperature
- A text about weather condition
Followed by default by the following current details:
- Feels Like temperature
- Wind
- UV index (only during daylight)
- Humidity
Details shown in header can be configured in the settings (Appearance). You can fit up to 4 details in portrait, and 5 details in landscape. You can configure more than 5 details because if some detail is missing from the source or if it’s nighttime (no UV), it will fallback to the next detail you configured in order. All details that you configured to display in header but don’t fit will be displayed in the Details card instead.
By default, cards are configured to display in this order and are all enabled:
- Daily forecast
- Hourly forecast
- Current air quality
- Current allergens
- Ephemeris (Sun & Moon)
- Current details
Some cards may not show with some sources if the data is not available. Check sources for more info.
On top of the first card, you have all current alerts listed with their starting time and ending time, if they are restricted to a period. If there are no alerts currently, but there are some scheduled for the future, it will be written, and you will be able to tap on the text to see the details of these future alerts.
Each day starts at 06:00 and ends at 29:59 (05:59 the day after). Days are split into two moments: daytime (06:00 to 17:59) and nighttime (18:00 to 29:59). Some sources might use slightly different hours, such as China from 10:00 to 19:59 and from 20:00 to 31:59.
Daily forecast is made of multiple tabs called trends. Order of daily trends can be changed in settings.
For each trend, the day of the week or "Today" is shown on top of each column, and just below, the day of the month and the month are shown.
When data is missing for the whole period, the tab will be hidden.
From top to bottom:
- Weather condition of daytime (icon)
- Maximum temperature of daytime (graph)
- Minimum temperature of nighttime (graph)
- Weather condition of nighttime (icon)
- Maximum precipitation probability for the whole day (bar + text)
If weather source has normals data, it will show two lines with maximum and minimum temperature normals for the month of the first day in forecast. If normals are not available, it will fallback to use a median maximum and minimum temperature for the daily forecast period.
Each column shows the maximum air quality index for the day (bar + text) from 00:00 to 23:59. More details about air quality index can be read in Air quality card section.
Bar color will have a different color according to air quality index:

Wind icons and speed bars have a different color according to Beaufort wind scale:

A line shows the alert level (7). It can be disabled in the settings (Appearance).
From top to bottom:
- Weather condition of daytime (icon)
- Total of all precipitation for daytime (bar + text)
- Total of all precipitation for nighttime (bar + text)
- Weather condition of nighttime (icon)
If total of all precipitation is 0, it will not be shown.
If total of all precipitation for all days is 0, precipitation trends will be hidden.
Each column shows the sunshine duration in hours for the day (bar + text) from 00:00 to 23:59.
Bar color is always light orange. It’s filled relative to the maximum daylight duration (from sunrise to sunset) of the daily forecast period. For example, if there are 6 hours of sunshine today, and the maximum daylight duration is 12 hours, the bar will be half-filled (50%).
Feels like temperature is the first available data from this list:
- RealFeel® temperature
- RealFeel Shade™ temperature
- Apparent temperature

- Weather condition of nighttime (icon)
- Maximum precipitation probability for the whole day (bar + text)
If weather source has normals data, it will show two lines with maximum and minimum temperature normals for the month of the first day in forecast. If normals are not available, it will fallback to use a median maximum and minimum temperature for the daily forecast period.
Just like daily forecast, hourly is made of the same tabs called trends. Order of hourly trends can be changed in settings.
For each trend, the hour of the week is shown on top of each column, and just below, the day of the month and the month are shown. If it is the first hour listed or if it midnight, the subtitle will be highlighted.
Below trends, a minute by minute precipitation quantity graph will be shown if precipitations in the next hour are above 0.
When data is missing for the whole period, the tab will be hidden.

Air quality uses the 2023 Plume index as a reference, and for SO2 and CO, it uses a similar scale based on WHO recommendations from 2021.
Here is the meaning of each category:
| Range | Title | Harmless exposure |
|---|---|---|
| 0-20 | Excellent | > 1 year |
| 20-50 | Fair | < 1 year |
| 50-100 | Poor | < 1 day |
| 100-150 | Unhealthy | < 1 hour |
| 150-250 | Very unhealthy | < a few minutes |
| > 250 | Dangerous | < 1 minutes |
Here are the thresholds:
| Pollutant | AQI 20 | AQI 50 | AQI 100 | AQI 150 | AQI 250 |
|---|---|---|---|---|---|
| O3 | 50 | 100 | 160 | 240 | 480 |
| NO2 | 10 | 25 | 200 | 400 | 1000 |
| PM10 | 15 | 45 | 80 | 160 | 400 |
| PM2.5 | 5 | 15 | 30 | 60 | 150 |
| SO2 | 20 | 40 | 270 | 500 | 960 |
| CO | 2 | 4 | 35 | 100 | 230 |
AQIs above 250 follow a linear progression.
An AQI is calculated for O3, NO2, PM10 and PM2.5 pollutant, and the general AQI is the maximum value of these four.
On the left, the ¾ circle shows the general AQI. On the right, you can see details of pollutants. Color bar is filled by the AQI value of the pollutant and not its measured value (to avoid having insignificant low-filled bars in non-polluted places in the world).
Both the circle and bars are filled with a different color for each category, so you can easily see the pollution level. The maximum value for the circle and bars is 250. At greater value, widgets will always be fulfilled.
Currently show allergens for current day, will be updated in the future to show for the current hour.
Only show allergens with at least one day where concentration > 0. The details of supported allergens by the source can be seen by tapping on the card and accessing the pollen details page.
Will be completed later
Arc show the progression of sun and moon during their course for the currently observed day. The starting point is the rise time (sunrise or moonrise) and the endpoint is the set time (sunset or moonset). The sun and the moon icons remain on the endpoint after they set for the rest of the day.
If there are two rise time (for example, the moon rises twice that day, or the moon already rose before 00:00 that day), only the first rise time after midnight for that day will be shown. The set time is the set time for that rise time, and can end up on next day. You will not be shown a set time before a rise time, even if one exists. If that information is important to you, we recommend using dedicated astronomy tools instead, especially as some weather sources might behave differently than what we just described (which is the general and fallback case).
When sun or moon is always up, it will be shown as rising at 00:00 and setting at 23:59. When sun or moon is always down, nothing will be shown.
Sunrise and sunset are shown on bottom left, and moonrise and moonset on bottom right.
Moon phase is shown on top right (text + icon).
The following details for the current weather will be shown if they are available:
- Feels like
- Wind
- UV index
- Relative humidity
- Atmospheric pressure
- Visibility
- Dew point
- Cloud cover
- Ceiling
Details already shown in the header will not be shown again.
In the footer, you have credits and acknowledgment for the weather source used for this location.
