October natural gas futures on Nymex finished higher on Tuesday, settling up 4.55% after prices rebounded from a one-week low. The contract, NGV26, rose 0.129 in the session as weather forecasts pointed to hotter-than-usual conditions in parts of the United States, supporting expectations of stronger power-sector demand for air-conditioning.
Key takeaways
- Price move: October natural gas futures (NGV26) closed up 4.55%.
- Catalyst: Forecasts shifted toward hotter weather across the South-Central US into early October.
- Demand implication: Warmer temperatures could lift electricity generation needs and increase cooling-related natural gas burn.
- Offsetting factor: Market attention remains on supply and storage expectations that point to ample inventories later in the season.
- Market context: Weekly storage and rig data continue to shape the medium-term balance between demand and supply.
What drove the rebound
Nat-gas prices regained strength Tuesday after a dip to a one-week low, with traders pointing to an updated temperature outlook. According to the Commodity Weather Group, forecasts turned hotter, with above-average temperatures expected in the South-Central US through October 6.
The immediate linkage for natural gas is to electricity generation. If temperatures run higher, electricity demand typically rises as households and businesses increase air-conditioning usage, which can boost power-sector fuel burn. That demand channel is a key driver for natural gas markets, particularly during shoulder periods when weather expectations can move quickly.
Supply and demand indicators remain mixed
Alongside the weather-driven demand narrative, several data points highlighted how the market continues to weigh near-term consumption against current supply conditions.
Data cited from BNEF showed lower-48 dry gas production at 112.2 bcf/day on Tuesday, up 3.1% year over year. Lower-48 state gas demand was reported at 74.6 bcf/day, up 0.3% year over year. Estimated LNG net flows to US export terminals were 18.5 bcf/day, down 0.6% week over week.
These figures suggest steady domestic production and demand growth, while LNG export flows were slightly lower versus the prior week—an important consideration for how much incremental demand natural gas receives beyond power generation.
Medium-term risks and supportive power demand
While Tuesday’s rally reflected a stronger demand backdrop from hotter forecasts, the article also pointed to longer-range headwinds that have been weighing on the market.
One bearish medium-term factor discussed is the market’s expectation that a “Super El Niño” could bring warmer-than-normal temperatures to parts of the Northern Hemisphere this fall and winter. Warmer conditions would reduce heating demand, which can limit upside in natural gas prices during the colder months.
On the supportive side, the Edison Electric Institute reported that US (lower-48) electricity output in the week ended September 12 rose 16.1% year over year to 94,427 GWh. It also said electricity output in the 52 weeks ending September 12 increased 3.3% year over year to 4,405,549 GWh. Stronger power generation can translate into higher gas consumption, reinforcing the demand story when temperatures trend upward.
Storage outlook and drilling activity
Natural gas prices also remained anchored to storage expectations and supply growth signals.
According to the US Energy Information Administration (EIA), projected storage levels could rise to 3,985 bcf by the end of October—described as the highest level in 10 years and about 5% above the five-year average. The EIA also raised its 2027 US dry natural gas production estimate to 116.0 bcf/day from 115.3 bcf/day projected in July, which points to continued supply growth moving forward.
However, recent inventory dynamics have been less bearish than might be implied by the later-season storage projection. The most recent weekly EIA report referenced in the article showed inventories increasing by 44 bcf for the week ended September 11—below expectations of 48 and below the five-year average of 74 bcf. As of September 11, inventories were down 3.9% year over year and about 3.7% above the five-year seasonal average, indicating adequate but not tightening supply.
On the broader demand side, the article noted that gas storage in Europe was 70% full as of September 20 versus a 86% five-year seasonal average for this time of year, which could influence how much attention market participants place on cross-Atlantic supply needs.
Finally, drilling activity remained an important watch point. Baker Hughes reported that the number of active US natural gas drilling rigs rose by 2 in the week ended September 18 to match a three-year high of 134, first set in February 2026. Higher rig counts can support production growth, which traders typically factor into the forward balance of supply and storage.
What to watch next
With Tuesday’s move driven by the weather outlook, market participants will likely monitor updates to temperature forecasts—especially into early October—as well as subsequent inventory reports that show whether storage builds stay below seasonal norms. Investors may also focus on the trajectory of power demand and further signals on US production and LNG flows, alongside ongoing policy and macro developments that can affect energy prices more broadly.
