Highest temperature in Tokyo on August 8?

Platform comparison

Market context

Tokyo’s hottest reading on 8 August will be set by the day’s maximum at Haneda Airport, not by a broad city forecast, so the market is really about one station’s intraday peak rather than the headline temperature shown elsewhere. At 09:00 UTC, Tokyo was already near 31°C in the official WBGT outlook, with the same source showing 31°C again around midday, which leaves meaningful room for a one- or two-degree move if late-morning sunshine or local heating pushes the station up further.[7] JMA’s August daily data already show Tokyo-area stations posting highs in the mid-30s earlier in the month, including 35.6°C at Haneda on 1 August and 33.0°C on 2 August.[1]

The current 0% YES price is easier to read as a funding and access signal than as a true weather view. On a market like this, book depth depends on how quickly traders can top up balances and exit profits: lower-friction deposits via Klarna-style on-ramp flows can attract smaller retail entries, while SEPA and USDC withdrawal rails make it easier to recycle capital across fast-moving weather markets. Comparable Tokyo temperature markets have resolved cleanly once the station’s daily high was pinned down by official data, and recent similar Polymarket listings have often finished near certainty when the realised temperature sat exactly inside a narrow bucket.[14][18]

The key catalysts are the late-morning to early-afternoon observations at Haneda and any updated short-range forecast from Japan’s weather services. Tokyo’s temperature profile can change quickly around solar noon, and the official environment forecast already points to heat stress conditions in the capital, which usually supports upside to the day’s maximum rather than a fade.[7] Traders should watch for fresh hourly station data from the resolution source and for any brief cloud or rain disruptions that could cap the high below the next bucket, especially if liquidity remains thin until the afternoon readout.

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.

How fast is SEPA deposit?

SEPA Instant: under 10 seconds. SEPA Standard: 1-2 business days. Both accepted fee-free; the internal USDC conversion runs automatically once EUR lands in the platform account.

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).
