D.C. is leaning toward a hotter than average summer, with even greater chances toward the Eastern Shore.

Why it matters: Enjoy our mild spring while it’s here; temperatures will dial up in the coming weeks!

🥵 The big picture: The climate outlook for June through August shows a broad swath of the lower 48 states and Alaska are likely to see a hotter than average summer, reports Axios’ Andrew Freedman.

Zoom in: In the Washington region, there is a 40-50% chance of above-normal temperatures starting next month through August, per NOAA.

🏖️ Bay watch: The Chesapeake Bay is split between a 40-60% chance of hotter than average days.

  • Beaches on the Eastern Shore have a 50-60% chance.
  • Plus, above-average sea surface temperatures are expected off the East Coast. (That, in turn, is also influencing the average weather over land.)

State of play: This week, highs are forecast in the 70s to low 80s — below normal.

  • Above average temps are expected over the next month.

Between the lines: The seasonal forecast is based in part on preexisting conditions, such as soil moisture which can enhance above-average temperatures, as well as the predicted formation of an El Niño in the equatorial tropical Pacific Ocean.

The intrigue: Worldwide, with ocean temperatures running at or near record highs globally, heat waves on land are even more likely.
