Market context
Wellington’s August daytime temperatures are usually modest, with climatology clustering around the low teens Celsius and only occasional spikes into the high teens, so a settlement above the mid-teens would already sit in the warmer tail of the distribution.[6][14] Weather Underground’s own historical page for Wellington shows a typical daily high near 53.7°F, or about 12°C, while comparable August summaries from other weather services put average highs around 12–13°C and rare extremes near 18°C.[13][14][15]
The market’s current 0% crowd-implied probability on an outright “YES” outcome looks consistent with that base rate, but the book can still move if forecast runs point to a brief warm-up around the airport station rather than the city centre. Traders should watch the final hourly forecast updates, because the contract resolves to the highest reading in Weather Underground’s Daily Observations table for Wellington Intl Airport Station, not the headline day-high figure, so a short-lived midday spike matters more than the general daily summary.[2][13] On the payments side, depth is typically strongest when deposits are easy to complete and cheap to recycle; Klarna-linked card funding can reduce on-ramp friction, while SEPA and USDC rails matter for traders who want to top up or withdraw without waiting on card settlement, keeping capital available for late repricing if the temperature track shifts.

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.
- Which payment methods are supported?
- Klarna (Pay Now / Pay Later), SOFORT, SEPA bank transfer, credit card (Visa/Mastercard), Apple Pay, Google Pay, and direct USDC deposit on Polygon. Availability depends on your jurisdiction.
- 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).
