Weather and Concrete: How Tennessee’s Climate Affects Your Pour
If you've lived or worked in Tennessee for a while, you know the weather can be unpredictable — sunny and 75° one day, pouring rain the next. And if you're planning to pour concrete, those swings in weather aren't just an inconvenience — they directly impact how your concrete sets, cures, and performs long-term.
At Orgain Ready Mix, we’ve poured concrete in just about every condition Tennessee can throw at us — heat, humidity, frost, even those oddball March snowflakes. Here's what we've learned over the years and what you need to know before you pour.
Hot, Humid Summers and Concrete Pours
Summer pours in Tennessee can be tricky. With temps often hitting the high 80s and 90s (plus humidity that feels like a wet blanket), concrete can set too quickly. That might sound like a time-saver, but it actually works against you.
Here’s what happens:
- Water evaporates too fast, leading to surface cracks.
- The mix may become difficult to work with, reducing finish quality.
- If not controlled, hot pours can weaken the concrete over time.
How we help:
At Orgain, we adjust our mix design during summer months and often recommend early-morning pours. We also provide retarders in the mix if needed, to slow curing and give your crew time to work the surface properly.
Cold Weather and Concrete: Slower, Riskier Cures
Concrete doesn’t like the cold either. In fact, once temps dip below 40°F, hydration slows down dramatically — and below 32°F? Water in the mix can freeze, stopping the curing process and potentially damaging the structure.
Here’s the risk:
- Slow setting can delay the schedule.
- Freezing temps can cause cracking before it fully cures.
- Risk of poor bonding to reinforcements or previous pours.
How we help:
Our team adjusts the mix for cold weather using accelerators, warm water, and scheduling advice. We’ll also talk you through insulating techniques like curing blankets or enclosures to protect your pour overnight.
Rain: The Most Common Surprise
It’s not unusual to have clear skies in the morning and thunderstorms by lunch. That kind of unpredictability can wash away surface cement, mess with finish timing, and cause long-term damage.
Before you pour:
- Always check the forecast for a dry 24–48 hour window.
- Cover the pour if rain is likely.
- Avoid finishing if water puddles on the surface.
How we help:
If the forecast looks iffy, we’ll help you make the call — reschedule, wait it out, or prep for rain. We’d rather you pour a day later than repair a job a month later.
Tennessee’s Seasonal Swings
Fall and spring are ideal times to pour — but they can shift fast. One cool front or heatwave can throw off your prep. That's why we always recommend working with a local team that understands Tennessee’s patterns — and how they affect concrete.
