<p>Curious about <strong>when does summer start 2025</strong> or <strong>when is the first day of summer 2025</strong>? Mark your calendars—this year, the <strong>2025 summer solstice</strong> lands on <strong>June 20</strong>, at <strong>10:41â¯p.m. ET</strong>, ushering in the <strong>1st day of summer 2025</strong> and the <strong>longest day of the year</strong> in the Northern Hemisphere. It&#8217;s the perfect moment to pause, soak up sunshine, and discover ancient traditions that continue to captivate us.</p>



<h2 id="what-makes-the-solstice-so-special" class="rb-heading-index-0 wp-block-heading">What Makes the Solstice so Special?</h2>



<p>On the <strong>summer solstice</strong>, Earth’s northern pole leans most toward the Sun, giving us maximal daylight and minimal night. In <strong>Washington, D.C.</strong>, folks enjoyed nearly <strong>15 hours of sunshine</strong>—from <strong>5:42â¯a.m. to 8:36â¯p.m.</strong>—with the Sun practically fixed at its highest sky position. Yet, astronomers distinguish between the <strong>astronomical season</strong> of summer, which starts at the solstice, and <strong>meteorological summer</strong>, which begins June 1.</p>



<h2 id="solstice-summer-rituals-ancient-to-modern" class="rb-heading-index-1 wp-block-heading">Solstice Summer Rituals: Ancient to Modern</h2>



<p>For millennia, cultures have celebrated <strong>summer solstice rituals</strong>, honoring fertility, rebirth, and the Sun’s power:</p>



<ul class="wp-block-list">
<li><strong>Stonehenge gathering:</strong> Devotees gather at dawn so the sun’s golden rays thread through the Heel Stone and illuminate the center.</li>



<li><strong>Midsummer flames in Scandinavia:</strong> Flaming bonfires, flower crowns, and communal dances ring in the season’s peak.</li>



<li><strong>Ivan Kupala in Eastern Europe:</strong> Ancient times of cleansing and luck, with water or fire rituals still alive today.</li>
</ul>



<p>Modern celebrations often include sunrise yoga, nature walks, or simply pausing to admire the extended daylight.</p>

<p>Although daylight peaks on <strong>when is summer solstice</strong>, <strong>summer 2025</strong> doesn&#8217;t start with a heatwave. Due to <strong>seasonal lag</strong>, Earth&#8217;s surface needs time to warm—so the hottest days typically land in <strong>July or August</strong>.</p>



<p>That said, <strong>Washington, D.C.</strong>, saw a high of <strong>87°F</strong> on solstice day—pretty much on historical average, with low humidity and breeze reaching <strong>26â¯mph</strong>. As summer rolls on, temps may climb into the <strong>90s</strong>.</p>
