Kalshi Weather Markets — Temperature & Rain Odds by City

Kalshi weather markets by city: daily high and low temperature and rain brackets with yes/no prices, volume, bracket bounds, unit and settlement station, plus the live airport observation (METAR) and 24h high/low. US and world cities. $1 per 1,000 markets.

Kalshi weather markets for any city, in clean rows, from Kalshi's own public API, with the live weather beside the odds. Type city names (New York, Chicago, Miami, Austin, Denver, Los Angeles, London, Paris, Tokyo, Seoul...) or codes (NYC, DC, EGLL) and get every daily high temperature, daily low temperature and rain bracket Kalshi lists for them, daily temperature first. Every row is one bracket: the question and outcome ("65° to 66°"), yes and no bid and ask (the implied probability), last price, 24h change, volume and open interest, and a weather block with the city, measure, bracket bounds as numbers (floor and cap), unit and settlement station (the NWS climate site, e.g. CLIMDW = Chicago Midway). With observations on (the default) each row also carries the latest airport observation (METAR) at that station: temperature in °F and °C, dew point, wind, present weather, the raw METAR and the high and low of the last 24 hours, from NOAA's aviationweather.gov. Use it for weather-trading models, mispricing alerts, forecast-vs-market dashboards and research. Also accepts weather series, event and market tickers. $1 per 1,000 markets, observations included, with no compute bill on top; problems return a free status row instead of failing.

What data does it return?

Every run outputs clean, schema-validated rows like these:

title	yesBid	city	station	nowF	high24hF
Will the maximum temperature be 70-71° on Oct 24, 2026?	0.62	Chicago	KMDW	53.1	71.1
Will the maximum temperature be 61-62° on Oct 24, 2026?	0.72	New York City	KNYC	45	57.9
Will the minimum temperature be >46° on Oct 24, 2026?	0	New York City	KNYC	45	57.9

How much does it cost?

Transparent pay-per-event pricing — you only pay for what you get, and the actor always respects your run budget: set a maximum total charge and it stops cleanly at the cap instead of overrunning.

Event	Price	Charged	Worked example
market	$0.001	per market row	1,000 weather markets = $1.00 (observations included)
apify-actor-start	$0.00005	per run per GB of memory (platform start fee)	One run at 256 MB = $0.00005

Input options

Field	Type	Required	Default	Description
cities	array	no	—	Optional cities for Kalshi weather markets (daily high and low temperature, rain, snow), e.g. New York, Chicago, Miami, Austin, Denver, London, Paris, Tokyo. Codes such as NYC, DC, LA or ICAO airports (EGLL) also work. Daily temperature brackets come first.
includeObservations	boolean	no	true	For weather markets, add the latest airport observation at the settlement station (temperature, dew point, wind, weather, raw METAR) and the high and low of the last 24 hours, from NOAA's aviationweather.gov. Indicative only: Kalshi settles on the official daily climate report.
seriesTickers	array	no	—	Optional Kalshi weather series tickers, e.g. KXHIGHNY, KXLOWTCHI, KXHIGHMIA, KXRAINNYCM.
eventTickers	array	no	—	Optional event tickers (e.g. KXFEDDECISION-26DEC) or kalshi.com market page URLs. A URL or ticker that names a series lists that series.
marketTickers	array	no	—	Optional exact market tickers, e.g. KXELONMARS-99. Returned whatever their status.
status	string	no	"open"	Open markets (trading now), closed markets (awaiting settlement), settled markets, or all.
minVolume24h	integer	no	—	Optional: skip markets that traded fewer contracts in the last 24 hours.
minOpenInterest	integer	no	—	Optional: skip markets with less open interest.
closeAfter	string	no	—	Optional: only markets that close on or after this date.
closeBefore	string	no	—	Optional: only markets that close on or before this date.
includeRules	boolean	no	false	Add each market's primary and secondary rules text.
includeOrderbook	boolean	no	false	Add a snapshot of the yes and no bids (price and contracts per level). One extra request per market.
orderbookDepth	integer	no	10	Price levels per side in the order book snapshot.
maxItems	integer	no	200	Upper limit on markets for the whole run. With no search, categories or tickers, the run lists open markets across Kalshi, newest first.

Limits & honest notes

• Responsible use: this is market data only. Nothing in it is financial, investment or betting advice, and prices are not predictions by ActorForge. Event-contract trading is restricted in some places; follow your local law and Kalshi's terms. This actor is not affiliated with, endorsed by or sponsored by Kalshi.
• It reads only Kalshi's documented public market-data endpoints and NOAA's public aviationweather.gov METAR API, with no key, no login and no trading, at most four requests per second with an honest user agent (ActorForge-Kalshi). The National Weather Service API (api.weather.gov) is not used because its robots.txt disallows automated access.
• Observations are indicative. Kalshi settles on the official daily climate report (or The Weather Company), which can differ from airport METAR by a degree or so, and "24h high/low" covers the last 24 hours, not the local calendar day. Rain brackets get no observation.
• The settlement station is read from each market's rules ("Chicago (CLIMDW)" → KMDW) or, for international series, from the ticker (KXHIGHTEGLL → EGLL). When METAR has no recent report for a station, the observation is empty and the row is still delivered.
• If Kalshi refuses a request or rate-limits the run, the run stops, keeps the markets already delivered and adds a free status row. Respects your run budget: set a maximum total charge and the run stops cleanly at the cap. Unknown tickers and empty searches return a free status row.
