Lowest temperature in Seattle on Jun 18, 2026?

Prediction market odds often diverge from traditional weather analyst forecasts because they incorporate real-time trader behavior, uncertainty premiums, and forward-looking sentiment.

Comparing the two reveals whether traders are pricing in more or less downside risk than official forecasts suggest, offering a complementary perspective on what the lowest temperature might actually be on that date.

As June approaches, short-range forecasts become more precise, typically triggering sharper price movements as uncertainty narrows and traders refine their bets.
