US natural gas futures jumped the most in two months on August 10, 2026, as an unexpected shift to hotter weather in the central and southern US sparked a wave of short‑covering. The rally was driven by money managers who had been the most bearish on gas since 2020, prompting them to buy back positions.

The turn in forecasts came from the private forecaster Commodity Weather Group, which now predicts above‑average temperatures across key consumption regions. Hotter conditions raise electricity demand as air‑conditioners run nonstop, forcing utilities to burn more natural gas and tightening the market balance.

As a result, US natural gas futures surged, marking the largest one‑day gain in over two months. Traders’ rapid covering of short bets amplified the price move, reinforcing the view that weather‑driven demand can quickly reverse sentiment in the gas market.

The price action underscores the volatility of natural gas, where a single forecast revision can trigger sharp reversals and highlight the importance of monitoring weather trends for energy traders and consumers alike.
