Today, San Antonio offers a mostly pleasant, albeit obstructed, outdoor workout experience. Don't let the good weather fool you; you'll still need to navigate around a city-wide construction zone.
- Overcast skies and a comfortable 20.8°C (about 69°F) mean you won't be battling the infamous Texas sun, making for pleasant conditions.
- Moderate pollen counts are still a real nuisance, so your lungs might not get a completely free pass, especially if you're prone to seasonal allergies.
- Expect detours and blocked paths due to the never-ending construction projects across our fair city. Seriously, plan ahead or prepare to get creative with your routes.
The Good, The Bad, and The Congested
The air quality today is actually pretty decent, with an AQI of 33. So, breathe easy on that front. The dominant pollutant is listed as "Ozone/Other," which, given the "good" rating, isn't something to lose sleep over. What will lose you sleep, or at least a good chunk of your morning run, is the sheer volume of construction.
Pollen Breakdown
| Pollen Level | Common Types (Unspecified, but typical for SA) |
|---|---|
| Moderate | Oak, Cedar, Ragweed, Grass |
Look, "moderate" pollen is still enough to make your nose run like a faucet and your eyes itch like crazy. Don't be a hero; take your meds if you're susceptible. Nobody wants to see you snotting your way down the Leon Creek Greenway.
Construction Chaos Continues
Our city is under constant construction, and today is no different. The Loop 1604 North Expansion Project is still a massive headache, causing frequent lane closures and impacting access around major thoroughfares. Just yesterday, a full highway closure was reported on Loop 1604 Northbound at SH 151 and Culebra, which thankfully cleared by 5 AM today, but it’s a sign of the constant disruptions.
Closer to home, several greenway trails are experiencing closures. A portion of the Leon Creek Greenway under the 1604 overpass is periodically closed through April. The Salado Creek Greenway, specifically the section from Gembler Road to Houston Street, is completely shut down until winter 2026 for maintenance, and other parts near the Tobin Park Trailhead are intermittently closed for TXDOT projects. Even the Mission Reach of the San Antonio River Walk has ongoing stem-density maintenance through Spring 2026, which can lead to temporary trail closures. Basically, assume your favorite path is partly, or wholly, inaccessible until further notice.
Mind the Mobs: Local Events
While not direct hazards, large events can mess with your flow. Today, April 11th, there's a "Save Our Children March" kicking off at Milam Park from 1-4 PM, with an SAPD escort. If your route takes you downtown, you might hit some pedestrian traffic or temporary street blockades. Also, the Guayabera Fest at Travis Park has Jefferson Street between Travis St. and Pecan St. closed until April 12th. If you planned a run through Travis Park, you'll need to reroute. On the brighter side, there's a free I-Cycle bike safety course happening at San Pedro Springs Park from 10-11 AM, which might draw a crowd if you're aiming for that park.
So, grab your tissues for the pollen, lace up your shoes, and for the love of all that is holy, check the city’s trail closure updates before you head out. You don't want to hit a "TRAIL CLOSED" sign three miles into your long run.
