Hurricane Season Opens: NOAA's Below-Normal 2026 Outlook
The Atlantic hurricane season opened June 1 with NOAA putting below-normal activity at 55%, near-normal at 35%, and above-normal at 10%. The useful tension is inside the forecast: El Niño should suppress activity, warmer Atlantic water and weaker trade winds push the other way, and none of it predicts who gets hit.

- SupportedNOAA issued its 2026 Atlantic hurricane season outlook on May 21, 2026.
- SupportedNOAA assigned a 55% chance to below-normal activity, 35% to near-normal activity, and 10% to above-normal activity.
- SupportedNOAA's 70% ranges are 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes.
- SupportedNOAA forecast 2026 accumulated cyclone energy at 45–115% of the median.
- SupportedThe 1991–2020 Atlantic seasonal averages are 14 named storms, 7 hurricanes, and 3 major hurricanes.
- SupportedEl Niño was expected to suppress Atlantic activity, while warmer Atlantic water and weaker trade winds were competing activity-supporting factors.
- SupportedNOAA's seasonal outlook describes basin-wide activity and is not a landfall or location forecast.
- SupportedThe Atlantic hurricane season runs June 1 through November 30, and NOAA expected an early-August outlook update.
What remains unexplained
NOAA makes below-normal activity the likeliest basin-wide outcome, but the season remains unscored and the outlook says nothing about specific landfalls.
- 01No seasonal activity forecast can determine which coastline, if any, a storm will affect.
- 02How quickly and strongly El Niño develops through the peak months remains uncertain.
- 03Warmer Atlantic water and weaker trade winds could offset part of El Niño's suppressing effect.
June 1, 2026. The Atlantic hurricane season opens with an official forecast that sounds reassuring until you read the ranges. NOAA's May 21 outlook makes a below-normal season the likeliest outcome: 55% below normal, 35% near normal, and 10% above normal. That is a forecast about basin-wide activity, not a promise about anyone's coastline.
What happened
NOAA gives a 70% probability of 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes. It also forecasts accumulated cyclone energy, or ACE, at 45–115% of the median. Those ranges sit around or below the 1991–2020 averages of 14 named storms, 7 hurricanes, and 3 major hurricanes.
The percentages and ranges answer different questions. The 55% figure says below-normal is the most likely overall category. The storm-count ranges describe what NOAA expects in 7 out of 10 seasons with similar conditions and uncertainty. Neither says the season cannot land outside those ranges.
The evidence
The main suppressing factor is El Niño, which NOAA expected to develop and persist through hurricane season. El Niño generally increases hostile conditions for Atlantic tropical cyclones. The competing factors are slightly warmer Atlantic water and weaker trade winds, both associated with a more active basin. NOAA's call is the balance of those forces, not a single-cause prediction.
The National Hurricane Center's climatology adds the calendar context. The official season runs June 1 through November 30, and activity usually peaks around September 10. A quiet June therefore would not settle the forecast.
What the outlook does not explain
NOAA is explicit: this is not a landfall forecast. Seasonal outlooks cannot say where or when a storm will affect land, and a below-normal basin can still produce a disastrous landfall. One storm can dominate a season that looks quiet in the aggregate.
The broad ranges are also part of the evidence, not fine print to hide. NOAA expected an early-August update after more of the atmosphere had shown its hand. If El Niño developed later or less strongly than forecast, activity could finish nearer the upper end; stronger suppression could pull it toward the lower end.
What's still open
The residue is simple: NOAA has described the basin, not the outcome. The season still has to reveal how strongly El Niño develops, whether Atlantic conditions counter it, where any storms track, and whether the August update changes the balance.
Below normal is the leading forecast. It is not an all-clear.
What is NOAA's 2026 Atlantic hurricane season forecast?
NOAA's May 21 outlook gives a 55% chance of a below-normal season, a 35% chance of a near-normal season, and a 10% chance of an above-normal season. Its 70% ranges are 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes.
Why does NOAA expect less Atlantic hurricane activity in 2026?
NOAA expected El Niño to develop and generally suppress Atlantic tropical cyclone activity. Slightly warmer Atlantic water and weaker trade winds are competing factors that can support activity, so the outlook reflects a balance rather than one decisive signal.
Does a below-normal outlook mean coastal communities are safe?
No. NOAA's seasonal outlook describes overall basin activity and is not a landfall forecast. A below-normal season can still produce a destructive storm, and seasonal models cannot identify a specific landfall months in advance.
What do NOAA's storm ranges mean?
NOAA says the forecast ranges should contain the season's activity in 7 out of 10 seasons with similar conditions and uncertainty. They are likely ranges, not minimums, maximums, or guarantees.
When does the Atlantic hurricane season run?
The official Atlantic season runs June 1 through November 30. Climatological activity usually peaks around September 10, and NOAA expected to update its seasonal outlook in early August.
Weird Weather
The Hessdalen Lights
Beginning December 1981, residents of a remote valley in central Norway started seeing bright luminous objects hovering and darting through the sky — sometimes 15 to 20 times per week. Forty years later, Project Hessdalen runs an instrumented observatory there. Spectrometers, magnetometers, and radar all detect the lights. Plasma, piezoelectricity, and scandium-ion mechanisms have been proposed. None fully account for what the instruments record.

Catatumbo Lightning
Over the mouth of the Catatumbo River, where it spills into Venezuela's Lake Maracaibo, lightning storms flare on 140 to 160 nights a year, up to nine hours at a stretch. It is Earth's most lightning-dense spot and holds a Guinness World Record. Far from a mystery, it is a textbook case of geography: mountains, a warm lake, and converging night winds that brew storms almost daily.

JWST Cycle 5: The Next Shot at K2-18b's Alleged Biosignature
JWST Cycle 5 begins observations around July 2026, and among its targets: K2-18b, the sub-Neptune 124 light-years away where a 2023 Cambridge-led team claimed to detect dimethyl sulfide — a molecule produced by marine life on Earth. A 2025 NASA-led reanalysis (Welbanks et al., arXiv:2508.05961) found the evidence does not meet the scientific standard of detection. Cycle 5 data could settle it — or complicate it further. This is the scientific method running in public, in real time.
