- 1This year's record El Niño and its global impacts●The impacts of this year’s record-shattering El Niño
The 2023-24 El Niño is described as record-shattering, with analysis of its wide-ranging effects on global temperatures, weather patterns and ecosystems. The event has driven exceptional ocean warming in the tropical Pacific, contributing to record global heat, shifts in rainfall, droughts and flooding in various regions, and stress on fisheries and agriculture. Commentators are weighing how much of the recent temperature surge should be attributed to El Niño versus longer-term climate change.
- 2Powerful El Nino Threatens California as Beaches Erode▼Powerful El Nino In Pacific Ocean Threatens California, Beaches Erode
A powerful El Nino event in the Pacific Ocean is threatening California's coastline, with beaches eroding as stronger storms and higher waves batter the shore. The phenomenon, which warms Pacific waters and alters weather patterns, raises concerns about coastal flooding, property damage and long-term loss of sand along California's popular beaches.
- 3Pacific's Nino 3.4 region hits record ocean temperature▼This is it people. The average ocean temperature in the Nino 3.4 region of the Pacific Ocean is now 29.822C. The previou
The average sea surface temperature in the Nino 3.4 region of the central Pacific has reached 29.822C, edging past the previous record of 29.815C set in 2015. Commenters warn the new record comes roughly two months earlier in the year than the 2015 one, suggesting ocean heating is still intensifying and could fuel a strong El Nino with global climate impacts.
- 4Scientists Warn Very Strong El Nino May Hit in 2026-2027▼NEDTalk—The Very Strong El Nino of 2026–2027: How a Warm Tropical Pacific Ocean May Reshape Weather Worldwide
The US National Environmental Satellite, Data, and Information Service is highlighting the outlook for a very strong El Nino in 2026-2027. The agency says an unusually warm tropical Pacific Ocean could reshape weather patterns worldwide, with potential effects on rainfall, droughts, storms and temperatures across multiple continents in the coming years.
- 5Hurricane Polo nears Baja California as Nolo threatens Hawaii▼Mexico's Baja California braces for Hurricane Polo as Hurricane Nolo threatens Hawaii https://www.npr.org/2026/09/28/nx-
Mexico's Baja California peninsula is preparing for the arrival of Hurricane Polo, with residents and authorities bracing for heavy rain, strong winds and coastal damage. Meanwhile, Hurricane Nolo is threatening Hawaii, putting the Pacific basin on alert with two simultaneous storm threats. Emergency preparations are underway on both sides of the ocean.
- 6Two Oceans Show Historically Unusual Hurricane Season Patterns▼Hurricane season is broken. Two oceans are historically out of whack
USA Today reports that hurricane activity is behaving abnormally across two ocean basins, with conditions described as historically out of whack. The Atlantic and Pacific seasons have both deviated from typical patterns, prompting meteorologists and readers to question how climate change may be reshaping storm formation, timing, and intensity this year.
- 7Concern grows over planetary-scale kelvin wave heading for California●Concern mounts over slow-moving, planetary-scale ‘kelvin’ wave heading for California https://www. theguardian.com/us-ne
A slow-moving, planetary-scale kelvin wave of warm ocean water is heading toward the US West Coast, raising concern in California. Such waves along the equatorial Pacific are tied to the El Niño-Southern Oscillation and can shift weather patterns, potentially bringing heavier rains, coastal impacts and extreme weather to the region as scientists and residents watch its progress.
- 8Two hurricanes churn simultaneously in the Pacific Ocean▼Two hurricanes churning in the Pacific Ocean
Two hurricanes are active at the same time in the Pacific Ocean, according to coverage from KING 5 and other outlets. Forecasters are tracking both storms' paths and potential threats to shipping, coastal areas and island communities. Dual Pacific hurricanes are drawing attention because concurrent systems can strain emergency preparedness and complicate forecasting.

Reports describe coastal erosion along California's shoreline, where cliffs and coastal land are collapsing into the Pacific. Rising seas, storms, and weakening bluffs are eating away at the state's famous coastline, threatening homes, roads, and beach communities. The story is drawing wide attention as a vivid illustration of how climate change and natural erosion are reshaping the American West Coast.
- 10Pacific hurricanes rage while Atlantic stays quiet, El Niño blamed▼The Pacific is churning with hurricanes. The Atlantic is quiet. Blame El Niño
El Niño conditions are driving an unusual split in hurricane activity: the Pacific is producing storms at a vigorous pace while the Atlantic hurricane season remains unusually calm. Forecasters attribute the contrast to El Niño's strengthening of winds that tear Atlantic storms apart, while simultaneously fueling storm development in the warmer Pacific. The pattern is shaping expectations for the rest of the season.
- 11Eastern Pacific Stays Active as New Atlantic System Emerges▼Tropical Update: Eastern Pacific Stays Active; Another area to watch in the Atlantic
Forecasters are tracking continued tropical activity in the Eastern Pacific while monitoring a new area of interest in the Atlantic. The update highlights two basins remaining watchful at the same time, with the Eastern Pacific keeping an active pattern and the Atlantic development zone being observed for possible organization. Details on timing, strength and tracks have not been released.
- 12Strong El Niño Seen Bringing Notable Impacts to the Midwest▼Regional Super El Niño Impacts: Midwest U.S.
A strong, or 'super', El Niño event is being linked to significant regional weather impacts across the Midwestern United States. The phenomenon, driven by unusually warm Pacific Ocean waters, typically alters precipitation and temperature patterns, affecting the Midwest's agriculture, flooding risks and winter conditions. Attention is focused on how this cycle may play out differently for the region.
