Market context
Shenzhen’s hottest reading for 6 August will be set by the daily maximum at Shenzhen Bao’an International Airport Station, so the key question is whether the city posts a typical late-summer high or an unusually strong spike before the settlement cut-off. August averages in Shenzhen are usually around 32°C, with humidity high and rainfall frequent, which means the distribution is often clustered in the low-30s rather than far above it.[3][13][19]
That framing helps explain why a 0% YES price can still be fragile: these temperature markets often clear on a single observation, and the result can differ materially from broader city forecasts if cloud cover, sea breeze, or convective rain suppresses the airport reading. A nearby reference point is the resolved 3 August Shenzhen temperature market, which settled YES, showing that a straightforward summer high can land in the market’s target range even when traders have priced in caution.[20] Hong Kong Observatory’s regional forecast for Shenzhen has already pointed to 26–34°C conditions and “fine to cloudy” weather, consistent with a warm but not extreme outcome.[4]
For a trader, the main catalysts are the morning and mid-morning forecast updates, any late-run thunderstorm or typhoon guidance, and the actual airport-side temperature trend before noon UTC. The settlement source is Wunderground’s history page for Shenzhen Bao’an International Airport Station, so the funding flow into this book tends to track how easy it is for users to top up quickly: lower on-ramp friction and cheaper rails such as SEPA or stablecoin deposits can support tighter books, while withdrawal convenience through options like Klarna-linked payments or USDC can matter when positions need to be recycled fast.

UK Frequently Asked Questions
- How does Klarna deposit work on Polymarket Klarna UK?
- You enter the deposit amount in EUR/GBP, choose Klarna as the method, run through Klarna's standard authentication (Pay Later or Direct Bank Transfer), and Polymarket Klarna UK converts internally to USDC for the Polymarket order book. Processing: typically under 30 minutes.
- What does SOFORT cost as a deposit method?
- Polymarket Klarna UK charges no fees for SOFORT. The only cost is the internal FX spread (typically <1%) on EUR→USDC conversion. SOFORT itself has no end-user fees — the platform absorbs acquirer costs.
- Can UK traders use Klarna to deposit on Polymarket?
- Polymarket does not natively accept Klarna. To fund a Polymarket account from the UK, you must first purchase USDC via a crypto exchange (Coinbase UK, Kraken) or Revolut, then transfer to a Polygon-compatible wallet. Some third-party on-ramps (MoonPay, Transak) accept UK debit cards and may support Klarna buy-now-pay-later for crypto purchases.
- What payment methods can UK users use for Polymarket?
- UK traders typically use: (1) Coinbase UK or Kraken — buy USDC with GBP debit card or bank transfer; (2) Revolut — buy crypto and send to wallet; (3) MoonPay or Transak — Visa/Mastercard UK debit card directly to USDC on Polygon. Standard GBP-to-USDC conversion fees range from 0.5–2.5%.
- How long do Polymarket withdrawals take for UK users?
- Polymarket withdrawals to your Polygon wallet are instant (on-chain). Converting USDC back to GBP via Coinbase UK or Kraken typically takes 1–3 business days for bank transfer, or near-instant for Revolut. Polygon gas fees are minimal (<$0.01 per transaction).
