Hawaii’s Broad Brush Weather Overview: A strong high pressure system far north will be disrupted by a developing kona low, forming just north of Kauai later tonight. Trade winds will break down today, and quickly veer from a more southeasterly to southerly direction by tonight. Deep unstable tropical moisture will produce bands of moderate to heavy showers across all islands.

The low center will move southeastward, passing just north of Kauai on Sunday, setting up west of the island chain on Monday. Expect elevated threats for flooding as these shower bands train across each island. Strengthening easterly winds as the ridge briefly builds back into the region will gradually reduce showers by Tuesday.

Hawaii’s Weather Details: A moderately strong high pressure system will remain in place far north of the Hawaiian Islands. Water vapor satellite imagery clearly shows a deepening upper level low roughly 800 miles north of Kauai, diving quickly south towards the Hawaii region. This upper level system will deepen over the next 12 to 18 hours, producing a kona low just north of Kauai. The surface low will follow the upper low on a southwesterly track passing just north of Kauai on Sunday, and then setting up west of the state by Monday.

Trade winds will initially break down today, then veer from a more southeasterly to southerly direction and strengthen from tonight into Tuesday. Wind speeds may briefly exceed Wind Advisory thresholds for most islands as the wind speeds peak on Monday.

This kona low weather pattern will bring in wet weather for all islands, under the influence of deep unstable tropical moisture across the area. Expect bands of moderate to heavy showers affecting all islands from late tonight through at least Monday. The threat from these shower bands potentially training over each island, has prompted a statewide Flood Watch from late tonight through Monday evening. Unstable showers may linger over some islands into Tuesday, which may extend the Flood Watch threat over these islands for one more day.

Thunderstorms are likely in this pattern, favoring the western islands of Niihau, Kauai, Oahu, Molokai, and Lanai through Monday. The Big Island may see isolated thunderstorm activity by Tuesday. Island by island impacts will highly depend on how these smaller scale shower bands form up and interact with island mountains. Large scale lifting under the influence of the upper level cold core low, and strong winds lifting these unstable clouds over island mountains will be the primary drivers of heavy rain, thunderstorm and flooding impacts. Take extra caution during this time period, as kona low weather patterns are one of the primary sources for our most severe heavy rainfall events in the Hawaiian Islands.

Deepening moisture will spread clouds and showers to even the highest summits of the Big Island during this event. Snow levels will likely fall to around the 11,000 foot elevation level, bringing periods of snow and freezing rain to the summits of Mauna Loa and Mauna Kea on the Big Island. Confidence on snowfall and icing amounts remain too low for any winter weather headlines at this time. Stay tuned as roads to the summit may become treacherous due to wintery weather during this time period.

Breezy east to southeast winds will slowly decline Tuesday and Wednesday as the low continues on a westward journey away from Hawaii, and a weak ridge briefly builds back into the region. A weak troughing pattern lingers near Kauai throughout the week, and there is some added uncertainty as to when the enhanced shower activity ends over the Garden Isle.

Hawaii’s Marine Environment: Trade winds will briefly weaken and veer southeastward by tonight across the coastal waters, as a low pressure system develops north of Kauai and begins to track southwestward. As this low passes just west of the state, strong to near gale-force east to east-southeasterly winds are expected to build Sunday evening, then continue through the first half of next week. The disturbance will bring rough seas, periods heavy rain, and isolated thunderstorms.

A moderate, medium-period north to north-northeast swell (360-030 deg) will continue to produce elevated surf, that is just below advisory thresholds along north facing shores. This swell will then slowly decrease through the rest of the weekend. In addition, this swell will likely produce moderate surges for north facing harbors, especially for Kahului and Hilo. A Marine Weather Statement will remains in effect for maritime interests to watch for these impending harbor surges. Meanwhile, a small, medium-period northwest (310-320 deg) swell will gradually decline through Monday. Another small, long period northwest (310-320 deg) swell is expected to arrive on Tuesday.

Aside from areas exposed to wrapping north-northeast swell, surf along east facing shores is expected to lower this weekend as trade winds weaken. However, a fetch of strong to near gale-force winds will significantly increase easterly wind swell Sunday night through the first half of the week, which should exceed advisory thresholds for east facing shores.

Surf along south facing shores will remain tiny through the forecast period.

Peak astronomical monthly tides with water levels running roughly 0.5 ft above normal could produce minor coastal flooding through the weekend, and may be enhanced along north facing shores due to the incoming north swell. A Coastal Flood Statement will remain in effect to highlight this flooding potential, especially during the daily peak high tide cycle.

Interesting:  Global temperature records shattered

Analyzing data from the Copernicus Climate Change Service of the European Union, AFP reports that Central Asia, the Sahel region, and Northern Europe experienced their warmest year on record in 2025.

Although, on a global average, 2025 ranks as the third warmest year after 2024 and 2023, these averages conceal the severe heat extremes faced by many countries.

As many developing nations do not regularly release detailed climate data, AFP conducted an independent analysis using Copernicus’ climate models, measurements from nearly 20 satellites, and data from weather stations worldwide.

Analyzing hourly data since 1970, the study found that in 2025 alone, 120 monthly temperature records were broken across more than 70 countries. These figures highlight the unprecedented speed and scale of global warming.

Central Asia experienced an exceptional year in 2025, with every country in the region breaking its annual temperature record. Tajikistan was among the hardest hit. In this mountainous, landlocked country, temperatures rose more than three degrees Celsius above the 1981–2010 seasonal average, ranking among the world’s largest recorded anomalies.

Only 41 percent of Tajikistan’s population has access to safe drinking water, exacerbating the humanitarian impact of the heatwaves. New monthly temperature records were set throughout most of the year, excluding May to November.

Alongside Tajikistan, Kazakhstan, Iran, and Uzbekistan saw temperatures two to three degrees Celsius above seasonal averages.

The Sahel region of Africa also recorded extreme heat in 2025. In Mali, Niger, Nigeria, Burkina Faso, and Chad, temperatures exceeded seasonal averages by 0.7 to 1.5 degrees Celsius. In Nigeria, the past 12 months were the warmest on record, while in other countries the period ranked among the top four hottest.

The World Weather Attribution Network reported in its 2025 assessment that human-induced climate change has increased the likelihood of extreme heatwaves nearly tenfold since 2015.

In the Sahel, already plagued by poverty, food insecurity, and conflict, rising temperatures have added further pressure on livelihoods and human well-being.

Europe faced an exceptional and dangerous summer in 2025. Switzerland and several Balkan countries experienced summer temperatures two to three degrees Celsius above seasonal averages.

Spain, Portugal, and the United Kingdom endured one of the hottest summers in history, triggering widespread wildfires. Thousands of hectares of forest burned across southern and western Europe, many residents were evacuated, and air pollution reached hazardous levels.

The situation in the UK was further complicated by the driest spring in a century, causing severe water shortages that affected agriculture and urban life.

Northern Europe was relatively spared from the extreme heatwaves that struck southern Europe in late summer but recorded an unusually warm autumn. Norway, Sweden, Finland, and Iceland experienced one of their two warmest years on record, accelerating glacial melt and raising new concerns for the region’s environmental balance.

The year 2025 has made it clear that climate change is not a future threat—it is a present reality.

No matter how global average temperatures are interpreted statistically, this heat directly impacts human health, food security, water supply, and ecosystems.

Scientists warn that unless effective and coordinated global efforts are taken now to reduce greenhouse gas emissions, years like 2025 will no longer be exceptions—they will become the new normal.
