# Highest temperature in Hong Kong on October 3: the evidence and conditions to watch The recorded daily maximum is the settlement variable. This observation date has already passed. Canonical article: https://www.homeincomelab.com/stories/highest-temperature-in-hong-kong-on-october-3-2026 Publisher: The Outlook By: The Outlook editorial desk Category: World Analysis as of: 2026-10-04T10:18:37.348448Z Decision guide market prices observed: 2026-10-04T09:57:48.323Z Published: 2026-10-04T10:18:37.348448Z ## Quick answer The recorded daily maximum is the settlement variable. This observation date has already passed. The observation window has passed; assess the official record and remaining settlement conditions. The contract’s current price expresses a traded expectation, not an official result.

Read the exact qualifying conditions before comparing related headlines. [2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) - The designated daily extract showing a value inside the selected range would support that range’s outcome. - A nearby station, rounded news report or later revision excluded by the rule may point to a different number without changing settlement. ## What this event actually asks The useful question is precise: Will the highest temperature in Hong Kong be 28°C on October 3? In the API observation at 09:57 UTC on 2026-10-04, the selected contract’s first listed outcome was priced at 0.05%. The parent event had recorded $100,439 in cumulative volume. This is turnover across the event, not a count of independent forecasters or proof that this outcome is correctly priced. [1](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026)[2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 3 Oct '26. [2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) The API still marks this event open for orders even though its scheduled end date has passed. This is a pending-resolution question, not a new future window. Assess evidence from the original interval and the rules for later confirmation. [1](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026)[2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) ## The recorded daily maximum is the settlement variable The Hong Kong Observatory provides daily extracts alongside monthly summaries and other climate series. Selecting the correct observation is essential: the rule here names the absolute daily maximum, not a forecast or a different station’s peak. [3](https://www.weather.gov.hk/en/cis/climat.htm) This observation date has already passed. The remaining question is which finalized value the rule recognizes and whether it has been published within the allowed interval. A forecast model’s best estimate cannot override that recorded value. ## Which evidence would change the assessment? The designated daily extract showing a value inside the selected range would support that range’s outcome. A nearby station, rounded news report or later revision excluded by the rule may point to a different number without changing settlement. ## The next useful checkpoint Written-rule date: October 3 (ET). The selected contract and any reporting grace period govern settlement. [2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) Our reading is conditional: compare the next primary record with the exact threshold above, then revisit the case if the evidence contradicts it. A high quoted chance does not establish certainty; a low quote does not make the event impossible. The value of the article is a clearer test of the claim, not an asserted trading advantage. ## A fact worth knowing The Hong Kong Observatory publishes daily, monthly and annual extracts as distinct climate records.

That price is the observation being analyzed, not an independent estimate of fair value. The separately timestamped live panel may differ.

Publicly available context can explain a price without proving that it is wrong; this article does not establish a positive trading edge. ## How the market resolves This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 3 Oct '26.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 3 Oct '26. [2](https://polymarket.com/event/highest-temperature-in-hong-kong-on-october-3-2026/highest-temperature-in-hong-kong-on-october-3-2026-28c) ### What evidence matters most for this outcome? The designated daily extract showing a value inside the selected range would support that range’s outcome. Read the linked rules for the exact evidence standard.

No. The recorded event volume is cumulative trading turnover, while the quote is a contract price at a stated time. Neither is an official finding about the underlying event.
