The National Hurricane Center says the Atlantic hurricane season runs from June 1 through November 30, with a climatological peak on September 10. Applied to the 2027 calendar, those fixed annual boundaries are June 1 and November 30, 2027. This page is an advance source guide for future searches about hurricane season 2027 dates and possible Kalshi hurricane markets. It is not a live market page.
Primary sources checked: August 4, 2026. The National Hurricane Center climatology page supplies the season bounds and peak, while the NOAA Climate Prediction Center Atlantic outlook page states the limits of a seasonal outlook. Kalshi's official API records annual series for hurricane counts, major-hurricane counts, and tropical-storm counts. Their exact open-event queries for hurricanes, major hurricanes, and tropical storms returned only 2026 events, not a 2027 event. The CFTC designation record establishes KalshiEX's general status, not event-specific availability or rules. Readers should use Kalshi's live markets directory and rulebook for current verification. No 2027 event ticker, contract, price, volume, liquidity, close time, settlement source, fee, eligibility rule, or availability was verified.
The NHC climatology page describes the Atlantic season as June 1 through November 30 and warns that tropical cyclone activity sometimes occurs before or after those dates. The same page identifies September 10 as the climatological peak and says most Atlantic activity occurs from mid-August through mid-October.
That gives this 2027 planning calendar:
These are NOAA season and climatology dates only. They do not establish when a Kalshi contract opens or closes, what observation window it uses, or when and how it settles. Those facts must come from the exact live contract rules.
The NOAA/CPC page available in this review was the 2026 Atlantic hurricane outlook. It did not provide a 2027 outlook or an official 2027 publication date. The safe update trigger for this guide is the appearance of an official 2027 outlook on NOAA's site, not an inferred date based on a prior year.
Critical limitations to understand:
A basin-wide seasonal outlook and a location-specific event are different questions. Neither the NOAA outlook nor the NHC calendar can substitute for the settlement language of a prediction-market contract.
Kalshi's public API confirms three relevant annual Climate and Weather series: hurricane counts, major-hurricane counts, and tropical-storm counts. At the August 4 snapshot, the exact open-event query for each series returned one event about the 2026 Atlantic season and no event dated 2027.
That catalog is evidence of subject coverage, not current availability. A series record does not show that a 2027 contract is open, available to a particular account, or governed by any assumed rules. Current status must be checked directly on Kalshi's official markets directory.
What the August 4, 2026 source review confirms:
What this review does not confirm:
If a 2027 hurricane result appears on Kalshi later, use this fail-closed checklist before treating it as a live source:
Step 1: Confirm the exact live page. Use Kalshi's official site and record the page URL and snapshot date. Do not copy a ticker from this article: none is provided.
Step 2: Read the full rules. Identify the exact question, definitions, observation window, close time, settlement source, and any revision or cancellation language. Do not infer these fields from the market title or from another hurricane series.
Step 3: Match the named source. If the contract names NHC, NOAA, or another authority, follow the exact product specified in the rules. A climatology page, seasonal outlook, advisory, and post-season report are not interchangeable.
Step 4: Verify current platform terms. Check any current fee, position limit, eligibility requirement, and account availability on official Kalshi pages. This snapshot states no amounts and makes no eligibility claim.
Step 5: Keep dates separate. June 1, September 10, and November 30 come from NHC climatology. They are not contract open, close, or settlement dates unless the exact rules say so.
This page can remain useful by separating confirmed event dates from editorial review dates:
The May 25 date is this site's editorial review schedule, not an agency release date or a Kalshi contract date. Any live-contract update also requires a fresh official Kalshi source snapshot.
Use NHC climatology for the season calendar and historical activity pattern. Use the NOAA/CPC outlook page only for the season and limitations it actually names. Use the exact live Kalshi page and rules for availability, ticker, pricing, trading window, eligibility, and settlement. If those sources do not answer a question, leave it unconfirmed.
The National Hurricane Center says the Atlantic hurricane season runs from June 1 through November 30. Its climatology page identifies September 10 as the peak, with most activity from mid-August through mid-October, while noting that storms can occur outside the season. These NOAA calendar facts do not determine any Kalshi contract's trading or settlement dates.
On August 4, 2026, three official open-event queries for Kalshi's annual hurricane-count, major-hurricane-count and tropical-storm-count series each returned one event about the 2026 Atlantic season and no event dated 2027. That snapshot does not prove what will be available later. Check Kalshi directly for current availability and exact rules.
No. NOAA says its seasonal outlook is not a landfall forecast and does not predict activity for a particular location. It provides basin-wide activity guidance, so it must not be treated as a forecast for a state, city, or coastline.
That cannot be determined from NHC climatology or Kalshi's annual series metadata. The exact live Kalshi contract rules must identify the settlement source, definitions, observation window, and timing. No settlement terms for a 2027 hurricane event were verified as of August 4, 2026.
