Riverside-San Bernardino is looking at a beautiful Sunday with sunny skies, a high near 84°F, and west winds between 0–15 mph with gusts up to 25 mph—ideal weather for getting outside and enjoying the Inland Empire.
This morning started cool, dropping to around 55°F overnight with partly cloudy skies. By mid-morning, those clouds will clear out, and you’ll have wall-to-wall sunshine through the afternoon. It’s a classic spring day for the region—warm enough to skip the jacket during the day, but you’ll definitely want one for tonight when temperatures dip back to around 51°F.
What to Do Today
If you’re planning a hike in Joshua Tree or heading up to Big Bear for a weekend escape, conditions are excellent. The light winds mean no Santa Ana hassle, and visibility will be outstanding. Golfers at courses around San Bernardino and Riverside should have a great day—bring sunscreen and stay hydrated. If you’re grilling at home or tailgating before one of this week’s playoff games (the Lakers take on Houston on Tuesday, April 21st at Crypto.com Arena), the weather is cooperating perfectly.
However, here’s the catch: spring pollen counts tend to spike in late April across our region. If you’re sensitive to oak, grass, or desert pollen, consider wearing a pollen count face mask during outdoor activities, especially if you’re spending hours in parks or on trails. An allergy relief nasal spray can be a lifesaver if you’re planning to be outside all day. If you’re heading indoors later, a HEPA air purifier with an air quality monitor can help keep your home’s air clean after a dusty day outside.
The Week Ahead
Monday brings more sunshine and a high near 81°F—still pleasant, but we’re tracking a low-pressure system moving into California that’ll cool things down and bring breezy conditions through mid-week. The National Weather Service mentions a slight chance of precipitation Tuesday afternoon into Wednesday morning as an upper-level trough moves through, though moisture looks limited. Don’t expect significant rain, but keep an umbrella handy just in case.
By Wednesday, expect cooler temperatures and persistent west winds, especially in the mountains and deserts. This is typical spring pattern for us—warm, dry days followed by marine layer influence and onshore flow keeping things refreshingly cool.
Tonight’s Dinner
With this perfect spring evening ahead, consider firing up the grill for some light, fresh fare—maybe grilled chicken with seasonal vegetables and a crisp salad. The mild temperatures mean you won’t be sweating over the barbecue, and the cool evening will be comfortable for eating outside. Did you know you can order groceries on Amazon? Get everything you need for tonight’s dinner delivered straight to your door.
Looking Ahead
Monday stays sunny and pleasant. Tuesday brings cooler air and those possible scattered showers. By Friday, expect cool, breezy conditions to persist as the system moves offshore. It’s a great setup for the week—enjoy today’s sunshine while it lasts!
