Boise is doing that thing again where it can’t quite decide if it’s spring or early summer—or maybe even winter-lite at night. If you’ve been battling the classic “Do I need a coat?” debate every morning, you’re not alone. This week’s forecast is giving us a little bit of everything: sunshine, warm spikes, cool breezes, and yes… record-breaking heat for one wild day.
Let’s break it down so you’re not caught off guard (again).
Tuesday: Light Jacket Vibes
It’s a pretty chill day—literally. Expect some clouds early on but more sunshine as we move into the afternoon. Highs will land in the low 60s, so it’s totally patio-lunch weather. Just keep that hoodie close, because temps will fall into the low 40s after sunset.
Wednesday: Starting to Feel Like Spring-Spring
This one’s a win. The sun sticks around (with some high clouds for drama), and temps climb up to the high 60s. It’s one of those days where everyone suddenly remembers they own bicycles and the greenbelt gets crowded. Evening temps hang out in the mid-40s—totally manageable.
Thursday: Whoa, Did Summer Just Show Up Early?!
Yeah, this is the big one. We’re talking 83°F—almost 20 degrees warmer than what we’re used to in early April. That’s record-breaking heat, folks. It’ll feel more like late June than spring. Break out the shorts and sunscreen, but also maybe ask the universe why your allergies are acting up. Even the evening stays warm-ish, with a low around 53°F.
Friday: Back to Reality
That heat doesn’t stick around. Friday’s looking cloudy and cooler, but still comfy in the low 70s. Not too hot, not too cold—just enough to keep you guessing. Grab a light jacket for later; the low dips back into the mid-40s.
Saturday: Breezy, Brisk, and a Bit Bitey
Ah yes, spring in the Treasure Valley. Sunny? Yep. Chill in the air? Definitely. Temps won’t climb past the mid-50s, and the wind’s got some sass. It’s great for a morning hike—just wear layers. And at night? It drops to freezing. Yep, 33°F. Bring your plants inside or cover them up.
Sunday: Meh, But Fine
Mostly cloudy and hanging around the upper 50s. Not a day you’ll write home about, but not a total wash either. A good one for errands or just chilling indoors. The evening’s still coldish at 35°F, so don’t toss that blanket just yet.
Monday: A Spring Reset
Boom—sun’s back, and so is that feel-good energy. Highs return to the mid-60s with clear skies. If you’ve been putting off outdoor chores, Monday is basically nature giving you the green light. Lows dip to the low 40s, but hey, that’s practically warm now.
