## What it is

A weather dashboard built around one fact that most weather sites ignore: a temperature contract
settles on a single instrument at a single named station, not on a city. Climate Sight gives each of
those stations its own page, keyed by ICAO code — KNYC for Central Park rather than "New York",
KMDW for Midway rather than "Chicago" — and puts three things on it: the latest observations, the
National Weather Service text products for that site, and a stack of model forecasts for that point.

The coverage page lists 71 stations. 29 are in the US, where contracts trade on Kalshi,
Polymarket, Robinhood and Interactive Brokers; the other 42 are the airports behind Polymarket's
international temperature markets, from Amsterdam Schiphol and London City to Taipei Songshan,
Tokyo Haneda and Wellington. Where one city has two contract stations, the site gives it two
pages: New York has Central Park and LaGuardia, Chicago has Midway and O'Hare, Dallas has DFW
and Love Field, Paris has Charles de Gaulle and Le Bourget.

The forecast stack on a station page, read from the page's own data on 30 September 2026 for
KNYC, runs to thirteen products: HRRR, RRFS, NAM-MOS, GFS, GFS-MOS, GEFS, HGEFS, NBM, GLMP, PFM,
ECMWF's IFS and AIFS, and Google's GraphCast. The MOS products and the National Blend matter more
than the raw grids here: they are already corrected for a specific station, and they are the
baseline that [where weather data comes from](https://predictionmarkets.tools/guides/where-weather-data-comes-from) argues any
home-built forecast has to beat. The about page says observations come from ASOS and AWOS station
data through NOAA's MADIS feed. The station page itself shows readings tagged as synoptic,
NOAAPort and METAR T-group records, the last carrying temperature to a tenth of a degree.

Around the dashboard sit an expected-value calculator, a strategy guide and a blog. The home page's
headline sells "ML-powered arbitrage signals", and a panel below it "ML buy signals (coming soon)";
the tools page lists a historical backtester over ten years of station data, also "(Coming Soon)".
All three are advertised, not shipped. None was live on the public site on 1 October 2026, no ship
date is given, and the strategy page says most of the approaches behind the signals are "in active
research currently". This card lists the data. Shipping the signals would put the headline over the
catalogue's scope line, which leaves out products that sell an opinion on what to buy, so the card
is re-checked against that line the day they ship.

## Availability

Nothing to deposit and no venue account required. The station pages load without signing in;
creating an account takes an email, Google, X or Discord login. The terms, dated 3 March 2025, set
no geographic restriction beyond the usual clause that visitors from places where the content
would be unlawful use it on their own initiative. They are governed by California law, give a San
Francisco address, and set a minimum age of 13, with parental supervision for minors.

What the site cannot do is give you access to a venue. A station page for Seoul or Lagos is
readable anywhere; the contract on it trades on Polymarket's international venue, which does not
serve US persons, and the US contracts listed beside it each have their own eligibility rules.

The privacy policy, last updated 10 August 2026, lists Google Analytics and Google AdSense among
the services the site uses.

## Pricing

The public station pages are free and need no account. The paid plan is the **Early Supporter
plan at 50 USD a month**, and the one place that price is written down is a blog post. There is no
pricing page (`/pricing/` returns 404), the sign-up form offers no plan, and the site map lists
none. The post announcing the plan, dated 30 December 2025, says "The price is currently $50/mo",
calls it a limited-time release, and says subscribing from the billing section of your account
unlocks "full access to the platform". Its listed benefits are early access to new features and
data streams, priority support, discounts on future plans and a Discord badge. Billing runs
through Stripe, and the support page handles invoice copies, seat changes and payment updates by
email.

What the plan unlocks is set out in later posts rather than in a plan table. The streaming API
launch post of 3 February 2026 says access "is available immediately for all Early Supporter Plan
members", so the API is not part of a free account. The ForecastWire post of 24 February 2026 says
its model forecasts are "live on every market page for Early Supporters". The card describes the
forecast stack from a station page's data and has not established how much of it a visitor
without the plan sees. No price is given for the advertised signals, which have not shipped.

The model is a subscription: the free pages are the dashboard with part of it held back, and the
monthly plan unlocks the rest of the same job. "Currently" and "limited time" mean the 50 USD is
the price of an early-access offer, not a list price the vendor has committed to.

Read from the Early Supporter, streaming API and ForecastWire posts, the home, tools and strategy
pages and the blog index on 1 October 2026, whose most recent post is dated 28 February 2026; the
sign-up, support and privacy pages were read on 30 September 2026.

## Markets & resolution

Nothing here resolves anything, and there are no market prices on the site. The station page's
"Exchanges" panel lists which contracts reference that station — for Central Park: Kalshi's
daily high, daily low and precipitation, Polymarket's temperature market, and Interactive Brokers'
high-temperature and snowfall contracts — and each carries the same line, that markets settle
based on official NWS climate reports.

That line is where to slow down. The Weather Company announced on 27 August 2026 that Kalshi uses
its feeds to verify weather outcomes, and Kalshi's certified rulebook lets the exchange name and
change the source agency per listing. A station page that still says "NWS climate report" for a
Kalshi series may be describing the previous arrangement. Which product, which clock and which
correction window decide a contract is set out in
[what a temperature market settles on](https://predictionmarkets.tools/guides/what-a-temperature-market-settles-on). The venue
cards — [Kalshi](https://predictionmarkets.tools/tools/kalshi), [Polymarket](https://predictionmarkets.tools/tools/polymarket), [Polymarket US](https://predictionmarkets.tools/tools/polymarket-us),
[Robinhood](https://predictionmarkets.tools/tools/robinhood-prediction-markets) and [ForecastEx](https://predictionmarkets.tools/tools/forecastex) — are where
the rules live.

The about page says the site follows the rounding rules and station specifications the exchanges
use. The public pages carry no documentation of what those rules are per venue, so treat it as a
claim to check rather than a specification.

## Integrations

A REST and streaming API, documented as an OpenAPI 3.1 specification at version `2026-01-01`, with
a Markdown twin of the reference for code assistants. Authentication is a bearer API key.
Endpoints list the settlement stations, list and fetch weather stations, and check the key. An
unauthenticated call to the station list returned 401 on 30 September 2026 while the health check
returned 200, so the service is live and gated.

Streaming comes two ways, and the documentation steers you firmly towards one. Server-sent events
are recommended for clients, unlimited in connection count, refreshed about every 400 seconds and
resumable by last event ID. A WebSocket is reserved for server-to-server use, needs a ping every
25 to 30 seconds, and has a per-account connection quota you ask support for. Both deliver the
same weather-point objects, with temperatures in Celsius and the raw METAR attached. The REST limit
is 120 requests a minute.

The API's own licence line is "All Rights Reserved". There is no SDK and no MCP server.

## Limitations

**No prices, so no comparison.** The site puts the forecast next to the station, not next to the
contract. Lining a forecast up against a strike price is left to you, through the calculator or
your own code, and the calculator takes whatever probability you give it.

**The settlement labels can lag the venues.** See Markets & resolution: the Kalshi line on each
station page names the NWS climate report, while Kalshi's weather source changed in August 2026.
The station is the part the site gets right. The source agency is something to read off the
contract every time.

**The price lives in a blog post.** The 50 USD Early Supporter plan is announced as current and
limited-time in a post from 30 December 2025, on a blog whose latest post is from 28 February
2026. There is no pricing page to tell a reader whether that offer still stands, and what it
includes has to be pieced together from three posts.

**The terms are restrictive for a data product.** No systematic retrieval of content to build a
database without written permission, no automated access by bot or script, no commercial use of
the content, and personal, non-commercial use only. Read that against the API, which exists
precisely for automated access, and settle the question with the vendor before building on it.

**Several advertised features are not built yet.** The machine-learning signals and the backtester
are both labelled coming soon, with no date, and the blog's most recent post was dated 28 February
2026, although the station data itself was current to the hour on 30 September 2026.

**"ASOS" is used loosely.** The coverage page labels all 71 sites "ASOS station", including
airports in China, Japan and Europe that are not part of the US Automated Surface Observing
System. Read it as "the airport whose reports the contract names".

## Alternatives

[OrcaLayer](https://predictionmarkets.tools/tools/orcalayer) has a weather monitor that lines Polymarket weather prices up against
live ECMWF and GFS runs, which is the side-by-side view this site leaves to you. It covers one venue,
and it flags disagreements rather than showing station records. If you would rather assemble the
same inputs yourself, [where weather data comes from](https://predictionmarkets.tools/guides/where-weather-data-comes-from) walks
through the free sources — the NWS API, NBM, the GFS and ECMWF open data — and what each licence
lets you publish, and [what an AI weather model gives you](https://predictionmarkets.tools/guides/what-an-ai-weather-model-gives-you)
covers what the AIFS and GraphCast rows on a station page are and are not.

## FAQ

### Does Climate Sight show the station a contract actually settles on?

That is how it is organised. Each page is one airport identified by its ICAO code — KNYC for Central Park, KMDW for Chicago Midway, LFPB for Paris-Le Bourget — rather than a city, and forecasts are stored per station. Whether that station is still the one a given contract names is a question for the contract's own rules, which a venue can change.

### Does it show Kalshi or Polymarket prices?

No. The station pages carry observations and forecasts and list which venues trade a contract on that station, but no market prices. The expected-value calculator takes a probability and a price that you type in yourself.

### Can I pull the data into my own code?

Yes, with an API key generated after signing up. The REST endpoints list the settlement stations and return station records, and a server-sent event stream pushes each new observation as it is ingested. The documented limit is 120 requests a minute. The vendor's blog says API access is for members of the Early Supporter plan, which it prices at 50 USD a month.

## Background

- [What a temperature market actually settles on](https://predictionmarkets.tools/guides/what-a-temperature-market-settles-on.md) — One named station, a day running midnight to midnight local standard time, and a number the government itself calls preliminary. Not the forecast you watched.

- [Where weather data comes from and what you may do with it](https://predictionmarkets.tools/guides/where-weather-data-comes-from.md) — Observations, model output and archives are three products with three licences. The forecast is the cheap half; a clean observation history is not.

- [Where a dashboard gets its data, and what it loses when that moves](https://predictionmarkets.tools/guides/where-a-dashboard-gets-its-data.md) — A venue API, an indexer or the chain itself. Which one a dashboard reads decides how far back its history goes and what vanishes when that source changes.
