The rules this check uses

Typical bagged-mix requirements for small DIY pours, scored against Logan's forecast above. The 48-hour freeze rule dominates every other row; structural work follows engineer/ACI specs instead of this table.

Typical label thresholds for concrete pouring — the ruleset behind every Logan verdict above.
CheckThresholdWhy it matters
Air temperature 40–90°F — ideal 50–85°F DIY pours work from 40–90°F; 50–85°F is the sweet spot.
Overnight low ≥40°F during the first 48 h A low under 40°F inside the first 48 hours puts you in cold-weather concreting — not a DIY window.
Dry before no soaking (≥1.0") in the prior 24 h What fell before you start matters as much as what falls after — surfaces hold water invisibly.
Dry after <0.1" rain for 6 h after (12 h light rain after finishing still risks surface marks) The make-or-break window: rain here undoes the work, not just delays it.
Wind ≤20 mph (rapid surface drying up to 28 mph) Scored on the windiest working hour; the marginal band changes the method, not the day.

Always follow your product label — formulas vary. Treat the table as the consensus range across brands — the label in your hand is the final word.

The working season runs May through September — about 98 workable days a year. The edges are night-limited: label rules want overnight lows of 40°F+, and Logan's nights only average that from May to September. Neighboring towns shift by a month or more — the Utah comparison shows where Logan sits.

Logan has a real wet/dry rhythm: January brings rain on 34% of days versus 13% in July. When the calendar gives you a July-side window, the dry-before and dry-after rules nearly take care of themselves.

Flip side of the driveway calendar: sealing in Logan opens later and closes earlier than pouring, on the same forecast.

Climatology here is measured at Logan Radio Kvnu, Ut Us (1.3 km away). Treat the monthly numbers as the neighborhood average; a shaded north-side deck runs colder and damper than any of them. The exact formula lives in the methodology.

For contrast, Lehi, UT’s concrete pouring calendar sits one stop back on this route, and concrete pouring in Ogden, UT is next in line.

Logan by the numbers

Prep checklist

  1. Check two nights, not one afternoon: both must hold 40°F+. In Logan that math works May through September — outside it, 14°F lows own the calendar.
  2. Stage everything before mixing: forms braced, base compacted and damp, tools rinsed, help booked.
  3. Cut plastic sheeting and weight it at the pour's edge — Logan sees rain on 19% of June days, and the 6-hour rule doesn't negotiate.
  4. Resist the watery mix: it finishes easier today and dusts forever after. Low slump wins.
  5. Work the sequence: screed on the sheen, float as it dulls, and leave bleed water alone.
  6. Edge and joint with an edger + float set — control joints every 2–3 slab-thicknesses in feet.
  7. Cure damp: sheeting or misting for days; against a Logan cold snap, a curing blanket guards the first 48 hours.
  8. Traffic schedule: feet at 24–48 hours, tires near day 7. Anything structural runs on engineer/ACI specs, not this checklist.

Frequently asked questions

What temperature is too cold to pour concrete?

For DIY: any low under 40°F within 48 hours of the pour — that's cold-weather concreting (blankets, accelerators, monitoring), not a weekend job. In Logan, nights average 40°F+ only May–September, which is what actually frames the season above.

Can you pour concrete before rain?

Only with 6+ hours of margin: a 0.1"+ downpour before final set washes cement paste off the finish. After set, rain helps the cure. Logan's January sees rain 34% of days — keep plastic sheeting cut and weighted at the pour's edge regardless of the forecast.

How long does concrete need to be protected from freezing?

48 hours minimum — that's when early strength forms, and ice inside that window scales the surface and weakens the slab for good. Logan's freeze risk lives at the season edges: January averages 31 nights under 40°F. Insulated curing blankets are the DIY answer to a surprise cold snap.

Is it OK to pour concrete in hot weather?

The ideal band is 50–85°F; 85–90°F earns a flag and 90°F+ is out. Logan's July highs average 89°F, so hot-weather tactics (dawn pour, shade, fast finishing) are standard kit in midsummer.

How long before you can drive on new concrete?

About 7 days for a passenger car in Logan's June conditions (79°F average highs — textbook cure speed); foot traffic after 24–48 hours. Cool weather stretches everything, because cure runs on temperature. Heavy vehicles wait longest, and the bag's schedule outranks any general rule, including this one.

Best season for concrete work in Logan?

The table above says June, August and September: enough warmth for the 48-hour cure, short of the 90°F ceiling. For small DIY pours that's the whole answer; structural pours schedule to engineer/ACI requirements, not to a best-months chart.

How windy is too windy to pour concrete?

Wind matters as much as temperature. Breezes above about 10 to 15 mph, especially with low humidity or warm sun, can evaporate surface moisture faster than bleed water rises — ACI guidance flags evaporation rates above 0.2 pounds per square foot per hour as plastic-shrinkage-cracking territory. For a small DIY slab, wait for a calm morning or rig windbreaks and fog-mist the air above the surface.

How long should I keep new concrete wet?

Keep it continuously wet for at least 7 days — the moist-curing period ACI guidance specifies for conventional concrete (3 days for high-early mixes). Use soaker hoses, wet burlap, curing blankets, or sheet plastic, or spray on a curing compound after finishing. Concrete allowed to dry out early can lose a large share of its potential strength and is far more likely to dust, scale, and crack.

When can I remove the forms from a small concrete pour?

For slabs, walkways, and post footings, side forms can usually come off 24 to 48 hours after the pour — leave them at least 72 hours when temperatures run below 50°F, since strength gain slows dramatically. Pry against the ground, never the green concrete, and keep curing the exposed edges afterward. Forms supporting structural or suspended concrete follow engineering rules, not DIY timelines.

How soon can I seal new concrete?

Wait until it reaches full cure — about 28 days — before applying most penetrating or acrylic sealers; sealing earlier traps moisture and can cause clouding or poor bond. The exception is a cure-and-seal product designed to go on the day of the pour. Pick a dry stretch with temperatures roughly 50 to 90°F — in Logan, June typically offers the most reliable window — so the sealer itself cures properly.

Concrete Pouring glossary

Evaporation rate
How fast surface moisture leaves fresh concrete, driven by temperature, wind, and humidity; rates above about 0.2 lb per square foot per hour invite plastic shrinkage cracking.
Plastic shrinkage cracking
Shallow, random cracks forming within hours of placement when the surface dries faster than bleed water can replace it; wind and sun are the usual culprits.
Bleed water
Mix water that rises to the surface after placement; finishing before it evaporates traps it under the trowel, creating a weak, dusty top layer.
Hydration
The chemical reaction between cement and water that hardens concrete; it needs moisture and temperatures above roughly 40°F, and continues gaining strength for weeks.
Curing compound
A sprayed or rolled membrane that seals moisture inside fresh concrete when wet curing isn't practical; some types must be stripped before paint or sealer.
Air entrainment
Microscopic air bubbles added to the mix that give exterior concrete freeze-thaw and deicer resistance; it must be ordered in the mix, not added later.
