PORTLAND, OR – Spring 2025 is shaping up to be anything but predictable. With warm breezes, frosty surprises, and storms lurking on the horizon, the latest long-range forecast from The Old Farmer’s Almanac is out—and it’s packed with twists for gardeners, farmers, and weather watchers. So what can folks in Portland, Oregon and the Pacific Northwest expect this spring? Well, we’re in for a surprise – but first let’s explore the science behind the Almanac’s weather predictions.

As the nation looks forward to blooming flowers and outdoor adventures, this spring could bring an unexpected mix of conditions. From intense thunderstorms to the threat of late-season frosts, here’s what you need to know before stepping outside.

What is Long-Range Weather Forecasting?

The Almanac uses something called Long-Ranger Weather Forecasting. It’s important to understand the science behind this model.

Unlike short-term forecasts that focus on daily weather, long-range forecasting takes a broader view. The Old Farmer’s Almanac uses solar science, climatology, and meteorology to predict weather trends for months ahead.

This method helps farmers, vacation planners, event organizers, and others prepare for what’s to come. By comparing expected temperatures and precipitation to historical averages, the Almanac delivers seasonal outlooks designed to guide everything from crop planting to travel plans.

Key Factors Driving Spring 2025 Weather

As Solar Cycle 25 intensifies, it could play a major role in warming trends. Historically, higher solar activity correlates with warmer global temperatures. This cycle is expected to peak by July 2025 and has already surpassed its predecessor, Solar Cycle 24, in intensity.

But solar activity isn’t the only player in this game. Several long-term ocean and atmospheric patterns are being closely monitored, including:

  • A weak La Niña phase of the El Niño-Southern Oscillation (ENSO)
  • A warm Atlantic Multidecadal Oscillation (AMO)
  • A cool Pacific Decadal Oscillation (PDO)
  • The Quasi-Biennial Oscillation (QBO), which involves equatorial stratospheric winds

These patterns are expected to influence both temperatures and rainfall, leading to a mix of warmer days and sudden cold snaps.

Spring 2025 Temperatures Across the U.S.

April could bring widespread warmth across the Intermountain West, but don’t get too comfortable—May may deliver a chilly surprise with the risk of late frosts in certain regions. This could spell trouble for crops and gardens if precautions aren’t taken.

What Can Portland Expect This Spring?

Here in Portland, Oregon and the Pacific Northwest, the Almanac says we’ll see shifting weather patterns

Temperatures will rise 3°F above average in April but will drop below normal in May.

The region will see slightly less rainfall than usual during the season.

Further Nationwide Trends by Region

Rainfall could be heavier than usual across much of the country, but not everyone will be reaching for their umbrellas. Dry conditions are predicted in regions like upper New England, southern Florida, the Heartland, Texas-Oklahoma, the western Ohio Valley, and parts of the Pacific Northwest and northern California.

Storm chasers should brace for a busy season, as severe weather is expected to be particularly active. The Deep South is on high alert for thunderstorms capable of producing damaging winds, hail, and tornadoes. Meanwhile, late-season snowflakes could make an appearance around the Lower Great Lakes, where colder-than-normal weather is expected during April.

Mother Nature’s Rollercoaster of Surprises

Spring 2025 could bring a rollercoaster of weather surprises. Whether you’re planting a garden or planning outdoor activities, this forecast is a wake-up call to stay prepared for anything Mother Nature has in store. Happy spring!
