Lowest temperature in Phoenix on Jul 4, 2026?

Prediction market odds reflect real-money incentives for accuracy, often diverging from traditional meteorological forecasts. While weather analysts rely on physics-based models and historical climate data, traders in this market incorporate broader information—including long-range ensemble forecasts, climate patterns, and consensus from other forecasters. The odds you see represent an aggregated bet on where the low will land, which can serve as a useful cross-check against published forecasts from the National Weather Service or other official sources.

This market resolves around Jul 5, 2026, once July 4, 2026 has passed and the actual low temperature is verifiable from credible public sources. The outcome is determined by the lowest temperature recorded in Phoenix on that date, measured against the specific temperature thresholds defined in each contract. Once the event occurs and data is confirmed, the market settles automatically and traders receive payouts based on which outcome bracket the actual low falls into.

Several factors could shift odds in this market: updated seasonal climate forecasts, historical temperature records for early July in Phoenix, shifts in El Niño or La Niña patterns, and long-range weather model consensus. Major atmospheric events—such as heat domes or unusual jet-stream positioning—can also influence trader expectations. As the date approaches, medium-range forecasts (10–14 days out) will become more precise, likely triggering sharper price movements.
