Concrete Pouring Weather in Hollywood, FL: 10-Day Windows & Best Months

By NOAA 1991–2020 normals, Hollywood keeps a concrete pouring window open in all 12 months — a year-round season few US cities match. The single best month is March, averaging 25 days that clear every check — highs of 79°F, lows near 63°F, and a 20% daily rain chance. Below: the live 10-day check and Hollywood's full month-by-month table.

The rules this check uses

Typical bagged-mix requirements for small DIY pours, scored against Hollywood'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 Hollywood 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.

Hollywood's calendar never really closes: even January, the leanest month, averages 24 workable days against the 40–90°F rules. The 10-day strip above matters more here than any season chart. Neighboring towns shift by a month or more — the Florida comparison shows where Hollywood sits.

Summer's enemy here is the rain gauge: July sees measurable rain on 49% of days, so back-to-back dry 6-hour cure windows come in streaks, not on schedule. The 10-day strip earns its keep in September (52% wet days).

The rain odds swing hard across the year — 20% of days in February up to 52% in September. Season the plan accordingly: prep in the wet months, apply in the dry ones.

Sealing the same driveway later? Sealcoating in Hollywood wants warmer nights (50°F+) than the pour did.

Climatology here is measured at Hollywood, Fl Us (3.4 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.

Hollywood by the numbers

Prep checklist

  1. Clear the 48-hour rule first: two nights over 40°F. March opens that door in Hollywood; January (59°F average lows) slams it.
  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 — Hollywood sees rain on 20% of March 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. Hold the moisture in (sheeting or misting); when March nights dip toward 63°F, a curing blanket is the difference.
  8. Traffic schedule: feet at 24–48 hours, tires near day 7. Anything structural runs on engineer/ACI specs, not this checklist.

FAQ

What temperature is too cold to pour concrete?

The line is a 40°F low inside the first 48 hours; an actual freeze (32°F) physically damages young concrete. Hollywood's January nights average 59°F — firmly out — while March nights hold near 63°F. Small pours only; structural work follows engineer/ACI specs.

Can you pour concrete before rain?

The engine wants 6 protected hours; light rain later actually feeds the cure. With 52% rain-day odds in September versus 20% in February, Hollywood's dry-season pours barely think about this rule and wet-season pours live by the radar. For small DIY pours; structural schedules follow ACI.

How long does concrete need to be protected from freezing?

Keep it above freezing for at least the first 48 hours (the engine calls any sub-40°F low in that window a NO). In Hollywood that rules out roughly January-adjacent months entirely and makes shoulder-season pours a two-night forecast decision. DIY scope; anything structural follows engineer/ACI cold-weather practice.

Is it OK to pour concrete in hot weather?

To a 90°F high, yes — with shade, cool mix water, a damp subgrade, and a dawn start. Above 90°F the surface sets while the core is plastic and shrinkage cracks map the slab. Hollywood averages 0 such days in July — rarely the binding constraint here.

How long before you can drive on new concrete?

A week before tires, 24–48 hours before feet — at March-typical Hollywood temperatures (79°F highs). When nights slide toward 59°F, add days: cure speed is temperature. Early loads print permanent marks; the bag's cure table wins every argument.

Best season for concrete work in Hollywood?

Year-round — the months with 40°F+ nights, sub-90°F days, and manageable rain. March leads at 25 workable days; January bottoms out near 24.
