Highest temperature in NYC on August 10?

Platform comparison

Market context

On 10 August 2026, the highest temperature recorded at LaGuardia Airport Station will determine this market's outcome. Resolution depends on the Daily Observations table from Weather Underground rather than the Day High & Low summary, a distinction that matters when intraday readings diverge from final summaries. The current 2% crowd probability reflects expectations of an unusually cool day for mid-August in New York City, where average highs in early August typically range from 27–29°C (81–84°F).

Historical August temperature records at LaGuardia show considerable year-to-year variation. The station recorded 38.3°C (101°F) on 9 August 2013 during an extreme heat event, whilst cooler Augusts have seen highs in the low 20s°C during unseasonal weather patterns. The 2% probability implies traders expect conditions substantially below the 30-year August median, suggesting either an unusual Atlantic weather system or a market pricing in tail-risk scenarios. Comparable markets on summer NYC temperatures typically see probabilities shift materially only when seasonal forecasts or atmospheric indices (such as the North Atlantic Oscillation) signal departure from climatological norms.

Traders should monitor the National Weather Service's extended forecast issued in late July 2026, which will clarify whether high-pressure systems or tropical systems are positioned to influence the Northeast. The Atlantic hurricane season's activity in early August may also affect upper-level patterns. Any official heat advisories or excessive heat warnings issued by NOAA in the week preceding 10 August would likely compress the probability distribution towards higher temperatures, whilst persistent cool-air advection from Canada would reinforce the current low-probability reading.

UK Frequently Asked Questions

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.

Is Polymarket regulated by the UKGC?

No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.

What are the HMRC tax rules on Polymarket profits for UK traders?

Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT). For 2026/27, the CGT rate is 18% (basic rate) or 24% (higher rate). The annual CGT exemption is £3,000. Report via HMRC Self Assessment if your total crypto gains exceed £3,000 or proceeds exceed £50,000.
