We had a very early start to spring in the West this year, it sustained, and now we can see that the "end" of spring was reached early to very early across pretty much all L48 states #statusofspring www.usanpn.org/data/maps/sp... @usa-npn.bsky.social #phenology

Pennsylvania grower starts long slog to orchard recovery

As spring arrives 10 days earlier on average than four decades ago, growers pay the price with total crop losses.

Got #pollen #allergies? You might find relief in less-well-lit rural towns than in brightly lit cities. Read more in my latest story for @snexplores.bsky.social bit.ly/3QZzmKF #lightpollution #phenology #pollenseason Interviews w/ Lin Meng, @theresacrimmins.bsky.social & @jonbennie.bsky.social

Got pollen allergies? Light pollution might make them worse

Light pollution in North American cities seems to be tricking plants into releasing pollen for longer periods each year.

The @usa-npn.bsky.social's Late Bloom Index is now live! This map shows where conditions associated with the conclusion of the spring season are being reached early or late. This year, the end of spring is quite early in the SW US; FL is average. www.usanpn.org/data/maps/sp... #phenology

Really nice article and visuals in @washingtonpost.com this morning showing how spring has arrived early - very early - in much of the lower 48 states www.washingtonpost.com/weather/inte... @usa-npn.bsky.social #phenology @bennollweather.bsky.social

See where flowers and leaves are emerging early after record-warm March

About 190 million people across the U.S. are experiencing an early start to spring, based on the behavior of lilac and honeysuckle, data shows.

With all the recent record-breaking heat in the western states, it's no surprise to see many locations starting spring green-up (L) and flowering (R) 2-4+ weeks early. Early start=early allergies. Subsequent freeze events could do major damage to crops. www.usanpn.org/data/maps/sp... #phenology

Parts of MT reaching leaf-out 30+d early this year. This very early spring is largely occurring in locations where things have been trending earlier over the past 4 decades #phenology www.usanpn.org/data/maps/sp... www.climatecentral.org/climate-matt... @usa-npn.bsky.social @climatecentral.org

I'm excited to join @climatecentral.org's Monthly Climate Brief on Thurs, Mar 19. We'll be talking about (surprise!) what is happening this spring and how you can get involved in tracking signs of the season. We'd love to have you join us! #phenology #statusofspring @usa-npn.bsky.social

Early signs of spring in WY - buds swelling on trees & shrubs. Lots of potential for subsequent freeze events there. www.newslj.com/local-trees-... @usa-npn.bsky.social growing degree day anomaly map clearly shows how much warmer than normal it has been so far this year #phenology #statusofspring

Do you suffer from cedar fever -- an allergy to mountain cedar (aka Ashe juniper, aka Juniperus ashei)? If so, I'd love to chat. I'm writing a book and want to include a brief bit from the perspective of someone whose life is severely impacted by pollen allergies. DM if interested! #allergies

A great reminder of the differences among astronomical, climatological, and phenological spring: www.bbc.com/weather/arti... #phenology #statusofspring

When does spring start in 2026?

As milder air sweeps across the UK it could start to feel positively spring-like in places. But when does spring officially begin?

The @usa-npn.bsky.social team will be celebrating #Pheology Week Mar 16-20 to coincide with the Spring Equinox. Join us for some fun and educational opportunities to celebrate the start of the spring season! www.usanpn.org/news/article...

All that cold the L48 recently experienced really slowed down the onset of spring. But we are starting to see things pick back up, with extra-early activity in the TX panhandle and through parts of AZ, CA, and up the west coast #statusofspring www.usanpn.org/data/maps/sp... @usa-npn.bsky.social

Our maps of heat accumulation provide a more scientific look at how much heat has accumulated so far this year. Our maps show that heat accumulation is ahead of schedule in much of the west, on time in the Midwest and upper Northeast, and behind schedule in the East.

According to predictions from NOAA's Climate Prediction Center, Phil may be right for parts of the Northern Great Plains - more cool temperatures are on the way! Much of the SW and SE should see above-avg temps in coming weeks and the NW, MW, and NE should see avg temps.

Punxsutawney Phil has made his annual prediction of what the next six weeks of weather will bring. According to Phil, more winter is on the way! But what does the science say? #GroundhogDay Keep track of Spring's arrival: usanpn.org/data/maps/sp...

Cedar fever got you feeling crummy? @usa-npn.bsky.social is collecting of Ashe's juniper pollen development and release through the NASA-funded PollenCAST project! Your observations of when junipers release pollen in TX will support real-time forecasts of airborne pollen usanpn.org/nn/campaigns...

And we're off! Spring has started to arrive in the most southern states, and in parts of TX, LA, and MS, it's >two weeks earlier than "normal" (the last 3 full decades). I feel like a broken record, we say this nearly every spring... #phenology @usa-npn.bsky.social usanpn.org/data/maps/sp...

Awesome @usa-npn.bsky.social partners Toby Ault and Carlos Carillo at @cornelluniversity.bsky.social released their long-lead forecast for spring; they are predicting a pretty early start to springtime activity in much of the U.S. six-ecrl-24.s3.amazonaws.com/index.html #phenology

Spring wildflowers are blooming earlier than in the 1800s... and it's the ones that flower earliest in the season that are showing the greatest shifts in their activity. Great work by Ryan Utz, @jmheberling.bsky.social, and crew: www.alleghenyfront.org/early-spring... #phenology

Early spring wildflowers are blooming even earlier thanks to climate change

Study authors used botanical records from over 100 years to explore how native wildflower bloom dates in Pennsylvania have changed due to climate change.

Writing for NYT, Margaret Roach looks at changing landscapes & weather patterns with new eyes, referring to "Phenology" author Theresa Crimmins' advice to "weave a practice of observing seasonal cycles of plants and animals into your life to contribute to science as well as soothe your soul":

New Rules for the New Year

Perhaps the best way to confront the swiftly changing landscape is to swallow hard, and then move forward with a fresh approach.
