Highest temperature in Shenzhen on August 18?

Platform comparison

Market context

Shenzhen will experience peak summer heat on 18 August 2026, with the highest temperature recorded at Bao'an International Airport determining the settlement outcome. The market resolves using Weather Underground's Daily Observations table rather than summary figures, a distinction that matters when intraday spikes exceed headline highs. Current odds reflect zero probability across all temperature bands, suggesting either incomplete market seeding or genuine uncertainty about liquidity depth at settlement.

Historical August temperatures in Shenzhen cluster between 32–35°C, with occasional peaks above 36°C during heat waves. The 2023 summer saw sustained readings above 35°C throughout August, whilst 2022 remained marginally cooler. These patterns establish a baseline: most traders pricing this market should anchor expectations around 33–34°C as the modal outcome, with tail risk concentrated in 36°C+ scenarios tied to tropical storm activity or anomalous high-pressure systems. The 0% crowd probability suggests either dormant order books or genuine disagreement on whether deposit friction justifies position sizing.

Traders monitoring this market should track China Meteorological Administration forecasts released in early August 2026, particularly any alerts for typhoon activity in the South China Sea. Bao'an's coastal location makes it sensitive to maritime weather systems; a tropical cyclone approach could drive temperatures down despite summer seasonality. Deposit rails matter here: traders using Klarna or SEPA transfers face 2–3 day settlement windows, whilst USDC on-ramps clear within hours. Book depth typically thickens as settlement approaches, rewarding early liquidity providers who can tolerate temporary illiquidity.

UK Frequently Asked Questions

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 I deposit with a credit card?

Yes, Visa and Mastercard. Credit card deposits carry a ~2.5% acquirer surcharge (standard for card payments). Apple Pay and Google Pay run on the same card rails — same surcharge.

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).
