Southerly
Weather, Reimagined Radially
$3.99 · Designed for iPad. Not verified for macOS.
Stop scrolling, start seeing. Southerly draws your weather - temperature, rain, wind and tides on one dial, so you read the shape of the day at a single glance.
Southerly shows your whole weather forecast as one beautiful infographic.
Instead of scrolling lists of numbers, you read the shape of the coming weather at a glance: time wraps around a radial dial, temperature colours the outer ring, rain blooms from the centre, and wind fans out as fine spokes. Turn the hand to any moment - the next 12 hours, 24 hours or seven days - and the dial answers the questions that matter: will it get warmer this afternoon? When does the rain arrive? Do I need my umbrella?
ONE DIAL, THREE TIMESCALES
Switch between a 12-hour, 24-hour or 7-day view. Each is a true clock face, so a given hour always sits in the same place - only the data moves. Drag the hand to scrub through time and the centre reads out the exact temperature, wind and conditions for the moment you pick.
THE RADIAL WEATHER
• Temperature ring: amber for heat, blue for cold - see the day's warmth at a glance. Dangerous UV is flagged right on the ring.
• Rain and snow: a blue bloom swells from the centre where precipitation is coming; even light drizzle shows clearly.
• Wind: fine spokes grow with the wind, with gust dots marking the difference between breeze and blast. Choose your unit - Beaufort, m/s, km/h, mph or knots.
• Day and night: the rim fades light to dark with real sunrise and sunset.
• Haptics: scrub the hand and feel the weather - the wind rise, the tide turn - with a firm tick at each midnight.
MANY PLACES, ONE SWIPE
Save the locations you care about and swipe between them. Add any city by search, or use your current location. Each place keeps its own real time zone, sunrise and sunset. Weather alerts are displayed beneath the dial.
GLOWS IN THE DARK
Dark Mode turns the dial into a night instrument: a luminous temperature ring, brighter rain, a shining tide line on a charcoal sky. It matches your device theme on first launch.
TIDES, BUILT IN
An offline tide predictor; harmonic stations worldwide backed by the FES2022 global tide model that fills in most other coastal locations, all computed entirely on your phone with no tide service and no connection needed. Note this is informational only - never rely on it for navigation or safety. We are actively working to improve the tides model for missing locations.
TE AO MĀORI & MARAMATAKA
Turn on te reo Māori and Aotearoa comes through: iwi place names, days and conditions in te reo, and the maramataka - the Māori lunar calendar. See tonight's named pō with its moon phase, the season's whetū, the lunar month (including Ruhanui in a Te Tau Toru Nui o Matariki year), and the Tangaroa nights favoured for predator trapping.
A STORY, NOT A SPREADSHEET
With Apple Intelligence, Southerly writes a short, plain-language summary of your next 24 hours - on device and offline - including underlying detail not shown on the chart. Note that your device needs to be recent enough to support Apple Intelligence.
FOR THE NAVIGATORS
Turn on Navigation for live heading, altitude and speed at your current position, plus a true-north marker on the dial.
YOUR UNITS, YOUR WAY
Choose °C or °F, millimetres or inches, and any of five wind scales.
PRIVATE BY DESIGN
Forecasts come from Apple Weather and place search uses Apple's own maps - no third-party data brokers. Tides and the weather summary are computed on your device. There's no account and no sign-in.
NO DATA COLLECTION, NO FORGOTTEN SUBSCRIPTIONS
This was built for our own use; we have no use or requirement for your data, nothing is collected. As much is possible is processed on-device including a global tide model, and Aotearoa placenames in Māori.
ACTIVELY DEVELOPED
This was built for our own purposes, particularly learning te reo Māori and the influence of maramataka on predator trapping here in Aotearoa/New Zealand. It's built for the latest iOS and supported back to iOS 18. We don't doubt there are things to be corrected and fixed, especially relating to maramataka, but let us know and we'll do our best.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Offline & reliability
- Forecasts saved on-device - works with no signal. So now when you're sailing, anchor behind that headland you'll still be able to use cached data.
- A failed refresh keeps your last forecast ("Offline · saved …" + tap-to-retry) instead of blanking.
- Fixed an airplane-mode hang (offline errors no longer retried).
- Recent data reused (10-min window); pull-to-refresh always fetches live.
Worldwide weather warnings (new)
- Non-US locations now get official warnings via the IFRC Alert Hub (US still uses Apple Weather).
- Alerts auto-expire (drop off the 7-day view once lapsed); per-alert source + link shown.
- Settings → Data Provider shows a passive "Worldwide Alerts" reachability status.
