City-wide forecasts miss your spot
A single icon for a whole metro tells you nothing about your park, your school field, your venue, or your construction site. Rain on the other side of town is not rain on your start line.
Hyperlocal · Pin-precise · Decision-grade
The weather at your exact spot.
Not the whole city.
City-wide forecasts are where every other weather app quietly fails. Anemo Signal blends information from multiple local and global platforms into one confident, hyperlocal answer for the exact pin you care about - the next hour, day, or event window. Built for runners on a sunrise loop, and for schools, event directors, and construction managers who actually have to make the call.
The problem
City-wide weather is not your weather.
Most apps give you a forecast for a whole city. The sky above your start line, your venue, or your site can tell a completely different story. That gap between "the city" and "this exact spot" is where every other weather product quietly fails you.
Microclimates change everything
A ridge, a coastline, a valley, a stadium bowl - each one bends wind, heat and rain by the hundred metres. Generic apps average those differences away. You feel them on the ground.
One source, one opinion
Every weather app picks a single provider and hopes for the best. When they're wrong, you're the one calling the parkrun, the sports day, or the concrete pour with no second opinion.
Anemo Signal is built for the opposite problem: not "what's the weather in the city", but "what's the weather at this pin, in this window, for this activity".
The Anemoi
Four winds. Four signals. One clear decision.
In Greek lore the Anemoi are the gods of the four directional winds and the seasons they bring. Anemo Signal translates each into a practical signal - so you always know whether to proceed, prepare, or stand down.
North · Winter
Boreas
Cold & Safety
Cold snaps, frost windows, wind-chill on early runs - the cold-air signal that keeps people warm and gear ready.
South · Summer
Notus
Storms & Alerts
Convective storms, lightning probability, gust fronts - the loud signal that triggers escalations and event holds.
East · Autumn
Eurus
Clarity
Visibility, humidity, comfort - the steady signal that says proceed, with the rationale spelled out clearly.
West · Spring
Zephyrus
Planning & Renewal
Forward windows, change-of-forecast diffs, parkrun mornings - the gentle signal that lets you plan with confidence.

Ask in plain language. Get a call you can act on.
Real questions from runners, schools, event teams and site managers - and the kind of hyperlocal answer Anemo Signal returns for the exact pin, window and activity.
You ask
Should I run my Sea Point promenade loop at 06:00?
8 km out-and-back · 60 min window
ProceedAnemo says
Proceed - clean window until 07:10
SSE breeze 14 km/h, gusts to 22, no rain on your pin in the next 90 min. Three of three sources agree. Confidence: high.
You ask
Is parkrun on at Constantia Greenbelt this Saturday?
5 km · 08:00 start · 45 min window
PrepareAnemo says
Prepare - light rain risk over your start area
30-40% chance of a passing shower between 07:50 and 08:25 at the pin. Wind benign. Bring a shell, brief marshals on slippery boardwalks.
You ask
Can I cycle the Helshoogte climb at 16:00?
22 km · 90 min window
DelayAnemo says
Delay 60 min - gust front incoming
Crosswind gusts of 48 km/h forecast at the pass between 16:10 and 16:45. After 17:15 the line clears and gusts drop below 25 km/h.
You ask
Walk with the dog now or after sunset?
Newlands Forest · 30 min window
ProceedAnemo says
Proceed now - heat drops fast after 18:00
Currently 28°C with low humidity at your pin. By 18:30 it's 22°C. Either window is safe; now is more comfortable for the dog.
How it works
Pin-precise. Not city-wide.
Most weather apps tell you what's happening somewhere in your city. Anemo Signal tells you what's happening at your pin - and what to do about it.
Step 1
Pin your exact spot
Drop a pin on the precise location you care about - your running route, school field, event venue or construction site. Not a suburb. Not a city. The actual place.
Step 2
Many sources. One answer.
We blend multiple local and global weather platforms in parallel, then merge them with a confidence score so you see where they agree on your pin - and where they don't.
Step 3
Decision-grade output
Our engine maps that hyperlocal forecast onto your activity profile and recommends: Proceed · Prepare · Delay · Move · Cancel · Escalate.
Step 4
Alerts that change with the sky
Set a watch and we'll re-check every 10-15 minutes. If the forecast shifts materially over your pin, we email you the why and the new call.
Stop second-guessing the sky.
Sign up free, pin your first location, and get your first decision in under a minute. Upgrade when your team or event needs more watches.
