The 2026 Atlantic hurricane season has produced just one named storm since June 1, making it one of the quietest starts in over a decade. But for Baja California Sur, that calm is misleading. The state sits along the eastern Pacific hurricane corridor, where El Niño conditions do not suppress storm activity and may actually fuel it. The peak months of August through October are still ahead.
El Niño and Atlantic Niña Create a Rare Double Shield Over the Atlantic
Two oceanic phenomena are working together to suppress Atlantic hurricanes this year. El Niño, officially declared in June, has warmed equatorial Pacific waters and altered global atmospheric circulation. That shift generates intense wind shear over the Caribbean and western Atlantic, tearing apart tropical systems before they can organize.
Wind shear over the Caribbean recorded its second-strongest early July reading since satellite records began in 1979. “The main characteristic of El Niño is precisely that wind shear,” said Michael Lowry, a Miami-based hurricane specialist. The shear has parked itself over zones that would normally be producing named storms by mid-July.
A second factor has compounded the effect. Sea surface temperatures in the equatorial Atlantic have dropped at least 0.5°C below average for consecutive seasons, a pattern sometimes called Atlantic Niña. That cooling has occurred only five times since 1980. Stronger trade winds push warm surface water away, allowing cooler deep water to rise. Hurricanes need warm ocean surfaces to form and intensify, so the cooling acts as an additional barrier.
The sole named storm so far, Tropical Storm Arthur, formed near the Texas coast in late June and made landfall within hours. Arthur caused flooding along parts of the Gulf of Mexico coast but dissipated quickly under the hostile atmospheric conditions now dominating the basin.
NOAA’s Climate Prediction Center updated its forecast on July 9. The agency reported a 97% probability that El Niño will continue into early 2027. It also projected an 81% chance that El Niño will reach “very strong” intensity between October and December. If those projections hold, the Atlantic could remain suppressed through the traditional peak months.
El Niño Enhances Pacific Storm Potential Near BCS
The two ocean basins operate on different systems. While El Niño creates hostile conditions for Atlantic hurricanes, it can enhance moisture and storm potential in parts of the eastern Pacific, including the waters off Baja California Sur.
Eastern Pacific hurricanes typically form off the coast of southern Mexico, near Acapulco and Manzanillo, then track northwestward along the Baja peninsula. The 2026 eastern Pacific forecast called for near-normal to slightly above-normal activity, and that projection has not changed despite the Atlantic slowdown. NOAA, the National Oceanic and Atmospheric Administration, and Colorado State University both noted that observed conditions align with expected behavior during El Niño years.
History supports the concern. Hurricane Odile struck Los Cabos as a Category 3 storm in September 2014, an El Niño year. That storm caused over $1.2 billion in damage, destroyed the San José del Cabo airport terminal, and left thousands of tourists stranded for days. Hurricane Norbert hit the region the same month. In 2023, Hurricane Hilary passed over the peninsula as a tropical storm, dumping record rainfall on La Paz, Mulegé, and communities along the Transpeninsular Highway.
Tropical Storm Fausto brushed the peninsula earlier this season, a reminder that Pacific systems can develop and approach BCS with little lead time. Storms forming in the warm waters south of the peninsula can strengthen rapidly, sometimes jumping from tropical depression to hurricane in 24 to 36 hours.
BCS Emergency Managers Urge Preparation Before August Peak
Protección Civil, the state civil protection agency in BCS, has urged residents not to draw false comfort from Atlantic headlines. The agency recommends completing storm preparations before August, when the eastern Pacific season historically accelerates.
Practical steps include inspecting roof integrity and sealing any weak points. Drainage systems around homes and condominiums should be cleared of debris. Storm shutters should be tested and secured. Residents in flood-prone areas, including parts of San José del Cabo’s Arroyo district and low-lying colonias near the La Paz malecón, should review evacuation routes now.
Emergency supply kits should include at least three days of water (one gallon per person per day), non-perishable food, medications, flashlights, batteries, and copies of important documents. Property managers overseeing rental units in Los Cabos, Todos Santos, and La Paz should confirm that tenants and guests have access to these supplies and know where to shelter.
Cell service and internet often fail during major storms. The state’s emergency radio frequency and local WhatsApp alert groups can provide updates when other communication goes down. Residents can register for municipal alerts through their local Protección Civil office.
The eastern Pacific hurricane season runs through November 30, with peak activity concentrated between mid-August and mid-October. NOAA will issue its next seasonal update in early August, with particular attention to whether El Niño’s intensification alters the Pacific storm outlook. The source reporting was based on NOAA and CNN data compiled by regional outlets.
