“November comes And November goes, With the last red berries And the first white snows.” - Elizabeth Coatsworth October Weather Summary If October felt like three seasons in one month, that’s because it was. Summer continued to stay late, the tropics finally woke up and fall arrived seemingly all at once. Here's a quick rundown of how the month unfolded: Summer’s last stand. Mid-October still felt more like July at times across the middle of the country. Over 1,000 high temperature records were broken in a single week throughout the Midwest, and the Twin Cities hit 90°F on back-to-back October days for the first time since records began there in 1871. The hurricane season finally showed up. After a record-quiet start, Isaias became the first Atlantic hurricane of 2026, ending an extraordinary four-month run with no Atlantic hurricanes since the season began on June 1. It made landfall on October 9th near Destin, Florida, with maximum sustained winds of 105 mph. Fall flipped the switch. Temperatures dropped about 40 degrees in just a few days, and much of the country from Texas to New England got its coldest air since spring, along with the season’s first widespread hard freeze in parts of the Upper Midwest and Plains. A nor’easter with a tropical twist. Late in the month, a nor’easter well off the East Coast strengthened into Subtropical Storm Josephine, the 10th named storm of the season. It stayed out at sea, but it still caused coastal flooding, high surf and beach erosion from the Carolina coast north through New England. What the Tempest network picked up: wherever you’re reading from, here’s how October looked across our U.S. stations. The month’s high came in at 112°F in Rancho Mirage, California, while La Pine, Oregon took the low at 7°F. A span of 105 degrees!

“It must be October, the trees are falling away and showing their true colors.” - Charmaine J. Forde September Weather Summary September played both sides of the season this year, opening with heat that felt more like August and closing with cool air and a coastal storm more typical of October. Here's a quick rundown of how the month unfolded: Starting the fall season with record-breaking heat. Much of the country spent the first half of the month feeling more like midsummer than early fall, with cities from coast to coast logging some of their hottest early-September days on record. Read More >>> Fall finally made its move. By mid-month, a blast of cool, dry air swept through the Midwest and Great Lakes, giving many of us our first real taste of sweater weather. Read More >>> Closing out the month with an early nor'easter. A rare September storm battered the Northeast with coastal flooding, heavy rain and high winds, weeks ahead of the usual nor'easter season. Read More >>> A hurricane season that didn't show up. September is usually peak hurricane season, but a powerful El Niño kept the Atlantic so calm that the season set a satellite-era record for the latest first hurricane. Read More >>> What the Tempest network picked up: wherever you're reading from, here's how September looked across our stations: the month's high came in at 117°F in Fort Mohave, Arizona, while Wise River, Montana took the low at 21°F.

Nor'easter season got an early start this year, as a powerful storm brought coastal flooding, erosion, power outages, and more than 6" of rain to parts of the Mid-Atlantic and Northeast at the end of September. The storm strengthened offshore before tracking into New Jersey. Its winds lasted for days, pushing water onshore and eroding beaches, while falling trees took down power lines. The heaviest rain fell across New Jersey, Long Island, and Southeast New England, and Tempest stations recorded each stage of the storm in real time.

"Delicious autumn! My very soul is wedded to it, and if I were a bird I would fly about the earth seeking the successive autumns." - George Eliot August Weather Summary August is often defined by heat, but this year the Midwest reminded everyone that late summer can bring some of the most damaging storms of the year too. On August 11, a line of powerful storms tore across the region, tracking nearly 400 miles from eastern Iowa through Chicago and into northern Indiana and the Ohio Valley. Wind gusts reached 99 mph in Gary, Indiana, with some damage assessments suggesting gusts closer to 110 mph in the hardest-hit areas, and several tornadoes spun up along the way. It was strong enough, and widespread enough, that it's already being treated as a preliminary derecho, pending official confirmation next year. Wherever you're reading from, here's what the Tempest network picked up across the country in August.

"When summer opens, I see how fast it matures, and fear it will be short; but after the heats of July and August, I am reconciled, like one who has had his swing, to the cool of autumn." - Ralph Waldo Emerson July Weather Summary July is peak summer season for most of the United States, and this year was no exception. High pressure dominated big parts of the Lower 48 for long stretches, driving prolonged heat and humidity along with it, while afternoon thunderstorms remained a consistent fixture in the Southeast and Gulf Coast. Drought conditions expanded in some western regions even as tropical moisture brought heavy rain to others, a reminder that "summer weather" rarely means the same thing across a country so large.

Earlier this month, we expanded our flagship high-resolution WRF forecasting model across the United States, giving more users access to the detailed weather intelligence they rely on to make the most of their time on the water.

"Summer afternoon—to me, those have always been the two most beautiful words in the English language." - Henry James June Weather Summary June delivered the transition most of the U.S. expects this time of year: the shift away from unpredictable spring storms and temps to the steadier heat patterns that define our summer. High pressure built across much of the West and South through the month, pushing temperatures up early and holding them there longer than typical for June. Meanwhile, parts of the interior West and higher elevations were reminded that summer doesn't arrive everywhere on the same schedule, with overnight lows still dropping into the 20s and teens in some mountain valleys. That range showed up clearly across the Tempest network.

On May 31, 2026, the wind sports community lost one of its founding figures. Hoyle Schweitzer passed away at the age of 93, leaving behind a legacy that reaches far beyond the beach breaks and river gorges where his influence is still felt today. Whether you windsurf, kitesurf, foil, or just love chasing the wind, his story is part of yours whether you knew it before now or not.

“In early June the world of leaf and blade and flowers explodes, and every sunset is different.” - John Steinbeck May Weather Summary May came in swinging and never really let up. Severe weather outbreaks kept the Plains and Midwest guessing throughout the month, while drought tightened its grip across parts of the South and West, fueling wildfires well ahead of schedule. The Gulf Coast contended with flash flooding from surging tropical moisture, and the Rockies weren't done with winter quite yet. Across the WeatherFlow-Tempest Network, May was anything but quiet, serving a vivid reminder of just how much the atmosphere can throw at us before summer even officially arrives.

"Among the changing months, May stands confest the sweetest, and in fairest colors dressed." - James Thomson April Weather Summary April brought the classic push-and-pull of a season still making up its mind…warm stretches giving way to stubborn cool spells, active storm tracks keeping the plains and Midwest on alert, and the kind of weather that reminds you spring is never quite done surprising you. Across the WeatherFlow-Tempest Network, the range of conditions was on full display.
