You’re waking up in Baldwin Park today, January 17, 2026, and honestly, the air feels a little different than your typical mid-January chill. Usually, we’re huddling in light jackets or complaining about the "marine layer" that never seems to burn off until noon. Not today.
Right now, it’s a crisp 65°F.
But don't let that morning coolness fool you. This isn't a day for heavy sweaters. We are looking at a baldwin park weather forecast that feels more like a sneak peek of early summer than a winter afternoon. By the time you’re heading out for lunch or hitting the 10 freeway, the mercury is going to climb all the way to a high of 81°F. That’s significantly warmer than the average January high of 68°F we’re used to seeing around here.
What’s Happening with the Baldwin Park Weather Forecast Today?
If you look outside, you’ll see some "partly sunny" skies. Basically, it’s that classic Southern California mix where the sun is trying its best, but there are enough clouds to keep things interesting.

The wind is barely a factor—just a light 2 mph breeze coming from the east. It’s the kind of day where the air feels still, almost expectant. Humidity is sitting at 35%, which is pretty dry. You might notice your skin feeling a bit tight or your morning coffee cooling down faster than usual.
The Numbers You Need to Know
- Today's High: 81°F (Get the sunscreen out)
- Tonight's Low: 49°F (Back to reality)
- UV Index: 3 (Moderate, so watch those mid-day rays)
- Rain Chance: 10% (Essentially, don't hold your breath for a car wash)
The gap between that 81°F peak and the 49°F overnight low is huge. It’s that famous California "diurnal shift." You start the day in a hoodie, end up in a t-shirt by 2:00 PM, and by the time you’re grabbing dinner at In-N-Out, you’re looking for that hoodie again.
Why is it so Warm in January?
Living in the San Gabriel Valley means we’re tucked into a specific geographic pocket. While the coast stays regulated by the Pacific, we get that inland heat trap. This specific baldwin park weather forecast is driven by a high-pressure system that’s keeping the usual winter storms up north toward Sacramento. While they're dealing with "atmospheric rivers" and mountain snow, we're basically enjoying a dry, warm bubble.
The humidity today is actually lower than the monthly average of 59%. That's a sign that the air is coming from the interior rather than the ocean. It’s not a full-blown Santa Ana wind event—the wind speed is too low for that—but it’s definitely "Santa Ana adjacent" in terms of how it feels.
Looking Ahead: Is the Heat Staying?
If you’re planning your week, keep those layers handy. This weekend is staying warm. Tomorrow, Sunday, is expected to hit around 82°F with similar partly cloudy conditions. We’re in a stretch of very warm, sunny days that should last through Monday before we see a slight dip back into the 70s by midweek.

Interestingly, while the baldwin park weather forecast shows a 10% chance of rain tonight, it's likely just going to manifest as increased cloudiness. The sky will turn "mostly cloudy" as the sun goes down, but the actual chance of getting your hair wet is slim to none.
Practical Tips for the Baldwin Park Heat Spike
- Hydrate Early: With humidity down to 35% and temperatures hitting the 80s, you’ll lose moisture faster than you realize.
- Pet Safety: If you’re walking your dog at Morgan Park today, do it before 11:00 AM or after 4:00 PM. Pavement can still get surprisingly hot when it’s 81°F out.
- Check the Pollen: Even though it’s winter, this warmth triggers "false spring" for plants. Ash and Alder pollen levels are currently in the medium-high range. If you’re sneezing, it’s not a cold—it’s the weather.
The bottom line is that Baldwin Park is currently an outlier compared to the rest of the country. While the East Coast is likely shivering, we’re pushing 80 degrees. Enjoy the sun, but keep a jacket in the car for that 49°F drop tonight.
Keep an eye on the sky around sunset. Those eastern winds and 10% moisture often make for some of the most vibrant, purple-and-orange sunsets the valley has to offer.
Check your local irrigation timers. With this sudden dry heat and low humidity, your lawn might need a quick supplemental drink if you’ve had the sprinklers off for the winter. Dress in light, breathable fabrics for the afternoon, but ensure you have a medium-weight fleece ready for any outdoor plans after 6:00 PM when the temperature begins its rapid descent toward the high 40s.
