Boston Experiences Unprecedented May Warmth

News Summary

This May, Boston residents are experiencing a remarkable increase in temperatures that feels more akin to summer than spring. Over the past few decades, the trend of rising temperatures in May has led to an average daily high of 68 degrees last year, with more days reaching the 70s and 80s. The warming trend is expected to continue as the National Weather Service forecasts a hot summer ahead for the Northeast, resulting in significant changes in local weather patterns.

Boston Experiences Unprecedented May Warmth – Is Summer Arriving Early?

As the heart of May rolls around, residents of Boston are witnessing something rather remarkable—this month is feeling more like summer than spring! Over the past three decades, our beloved New England has experienced a significant warming trend, transforming the normally frosty days of May into more temperate, sun-kissed afternoons, setting the stage for plenty of outdoor activities.

The Changing Face of May

Let’s take a moment to understand just how much May has evolved. Traditionally, this month acts as a bridge between the glories of spring and the warmth of summer. In recent years, however, data indicates this transition is becoming ever more pronounced, with fewer lingering chilly spells and a steady increase in those delightful, warm days.

For instance, the usual high temperature for May hovers around 65 degrees, but last year’s average daily high shot up to a cozy 68 degrees. Now, that may not seem like much, but when you consider that Boston typically enjoys 12 days in May with temps breaking into the 70s and about four days hitting the 80s, it becomes clear that we’re living in a new norm.

Days in the Sun

The number of days when the mercury hits the 70s or 80s in May has been steadily climbing. In fact, Boston has celebrated multiple occasions of sun-soaked weather over the past five years. The standout years of 2010, 2015, and 2018 showcased spectacular warm spells. In those years, it wasn’t unusual to see multiple days leap into the 80s, with average daily highs significantly surpassing the typical benchmarks.

To paint a clearer picture, during these hot May periods, Boston recorded:

• 2010: An average of 72 degrees, with 19 days over 70 degrees and 8 days hitting 80 degrees, plus one day reaching a sweltering 90 degrees.
• 2015: The average climbed even higher to 73 degrees, with the same impressive number of days in the 70s and added days in the 80s.
• 2018: This year had a slight dip to an average of 71.7 degrees, yet still saw 15 days above 70 and 11 in the 80s, plus another day spiking to 90!

Warmer Nights Ahead

But wait, there’s more! Nights in May are becoming warmer as well, a trend underscored by May 2024 setting a record for the warmest nightly average temperatures ever experienced in the month. Along with warmer nights, increased atmospheric moisture plays a role in elevating temperatures, providing that sultry feel to our evenings!

What’s Ahead?

Looking further into the future, the data scientists hint that May 2025 may finally deliver some typical temperatures as we experience a neutral phase between El Niño and La Niña conditions. Thankfully, predicted sea-surface temperatures off the New England coast are forecasted to cool slightly as well; this could mean the usual chilling breezes of May will make a comeback.

The National Weather Service is buzzing with news of a hot summer ahead, forecasting temperatures to be 50-60% above normal for not just May, but also June and July in the Northeast. As for rainfall, we might see a little more than usual, with exceptions noted by regional trends, ensuring our gardens stay vibrant and green.

The Bottom Line

So, as we bask in the warm rays of May, it’s clear that the climate changes we’re witnessing aren’t just fleeting—this warming trend is significant and real. Whether enjoying an afternoon barbecue or relaxing at the beach, one thing is for certain: Boston has a new vibe, and summer seems to be waiving hello!
