El Niño conditions, now confirmed by NOAA with strengthening projected through summer 2026, represent the dominant driver behind trader sentiment favoring lower July tornado counts. This pattern typically shifts the jet stream and reduces moisture and shear favorable for supercells across the central and eastern US, aligning with near- or below-average seasonal outlooks. Historical July baselines average around 119 tornadoes, yet recent atmospheric blocks and High Plains drought have kept severe activity quiet into mid-June. Market probabilities clustering between <100 and 100–129 reflect uncertainty in the strength of El Niño suppression versus potential late-month pattern shifts, with higher bins priced lower due to limited analogs for elevated summer activity under similar ENSO states.

Only tornadoes appearing in the final NCEI dataset for that month will count.
As of market creation, the relevant report is scheduled to be released on August 10, 2026, at 5:01 PM GMT+1 or 11:00 AM ET (Release schedule: https://www.ncei.noaa.gov/access/monitoring/dyk/monthly-releases). The market will resolve based on the first relevant tornado count published on the NCEI tornado time-series page after this scheduled release time.
If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments.
The market will not resolve based on any preliminary values published before the scheduled release time.
If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication ET, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.
