The rules this check uses

Each verdict above is this table applied to Fort Lauderdale's forecast. Standard latex rules, with the 35°F-rated formulas handled as a marginal band, not a pass.

Typical label thresholds for exterior painting — the ruleset behind every Fort Lauderdale verdict above.
CheckThresholdWhy it matters
Air temperature 50–90°F (low-temp formulas from 35°F) Checked across the working day, 8 a.m.–6 p.m., against Fort Lauderdale's hourly forecast — not just the daily high.
Overnight low ≥35°F during the first 24 h (≥40°F preferred) The engine reads every overnight hour in the cure window, not just Fort Lauderdale's forecast low.
Dry before ≤0.05" rain in the prior 12 h; watch back to 24 h The surface must be dry to the touch and out of a recent soak.
Dry after <0.05" rain for 24 h after Rain inside the first 24 hours can streak or wash fresh paint.
Evening dew-point spread ≥5°F from 6–11 pm Scored on the worst hour between 6 and 11 p.m., when surfaces cool past the air.
Daytime humidity ≤80% High humidity extends recoat and cure times.
Wind ≤15 mph (brush only up to 20 mph) Wind wrecks application first (drift, lap marks) and carries debris into wet work second.

Always follow your product label — formulas vary. These rows are the industry-typical range; the can in your Fort Lauderdale garage is the contract.

Figure 207 workable days a year in Fort Lauderdale, spread across September through June. Shoulder months turn on the overnight rule: an afternoon at 89°F passes, but the 40°F night floor is what actually opens the season in September. For the statewide picture, the Florida page compares peak months city by city.

July here fails on heat, not rain: the average high of 90°F sits over the 90°F label ceiling, and 28 of 31 days typically top 90°F. Midsummer work moves to dawn or waits for March.

The rain odds swing hard across the year — 21% of days in February up to 49% in September. Season the plan accordingly: prep in the wet months, apply in the dry ones.

If the walls pass, the roof might too: roof coating in Fort Lauderdale uses the same film chemistry with tighter dew and wind limits.

Numbers above come from NOAA's 1991–2020 normals for Ft Lauderdale Beach, Fl Us, 4.0 km from the city center — close enough that neighborhood microclimates (shade lines, river valleys, urban heat) matter more than station distance. See how these day counts are scored.

Fort Lauderdale by the numbers

Prep checklist

  1. Find application day plus 24 dry hours with nights at 40°F+; Fort Lauderdale offers that pairing most often in March (24 workable days).
  2. Prep is the coat that matters — wash off chalk and mildew, scrape to sound edges.
  3. Give washed siding 24 hours — north walls in Fort Lauderdale can need double after a September-grade soak.
  4. An ir surface thermometer settles arguments: label limits bind the wall surface, which outruns Fort Lauderdale's air by 20°F+ in sun.
  5. Prime bare wood and stains; caulk once the surface is dry to the touch.
  6. Sequence walls so you always paint in shade; midday sun skins latex before it levels.
  7. Cut in with an angled brush set, roll a wet edge, and drop the sprayer plan over 15 mph.
  8. Stop 2 hours before sunset: with March lows near 64°F, Fort Lauderdale's siding meets the dew point before the late news.

Frequently asked questions

What temperature can you paint outside?

50–90°F for standard formulas, 35°F+ for low-temp lines, and the wall itself must stay 5°F above the dew point. In Fort Lauderdale the practical range is set by nights: the 40°F overnight floor arrives around January and leaves after December.

How many dry hours does exterior paint need before rain?

Plan 24 rain-free hours after the last coat; the engine fails any day that can't deliver them. With Fort Lauderdale's rain odds swinging from 21% of days in February to 49% in September, the strip above is mostly a search for that dry pair.

Why does dew ruin fresh paint?

Fresh latex needs hours before it can take standing water; evening condensation gets there first on cooling siding. The check: air minus dew point from 6–11 p.m., 5°F or better. Humid September evenings in Fort Lauderdale are when GOOD afternoons hide failing nights.

Can you paint in high humidity?

Up to about 80% daytime RH — above that, dry times stretch until the film meets the evening dew. 80–83% reads MARGINAL on the engine; more is a fail. Pair humidity with Fort Lauderdale's dew-point spread rule and paint mornings-into-early-afternoons in the humid months.

What is surface temperature vs air temperature?

Two different numbers: air (what the app shows) and the wall (what the paint feels). Sun adds 20°F or more; evening radiational cooling subtracts. That's why the engine checks the 90°F top on Fort Lauderdale's hot afternoons and the dew-point spread after sunset — both are surface problems the air forecast hides.

When does painting season end in Fort Lauderdale?

When nights stop clearing 40°F — in Fort Lauderdale that's typically after June, when average lows hit 76°F and falling. Low-temp formulas (35°F rated) buy a few extra weeks; the engine shows them as MARGINAL days before the hard close.

What humidity is too high for exterior painting?

Most acrylic paints apply well between 40 and 70 percent relative humidity. Above about 85 percent, water can't evaporate from the film, so drying stalls, sags develop, and surfactants rise as sticky brown streaks. Very low humidity under 20 percent causes the opposite problem — paint dries too fast to level. Check the hourly forecast for Fort Lauderdale and aim for a falling-humidity afternoon.

What is the dew point rule for exterior painting?

Coating manufacturers require the surface to be at least 5°F above the dew point during application and initial drying. Closer than that, an invisible film of condensation forms on the siding, which ruins adhesion and can flash-rust bare metal. Practically, start after morning dew has fully evaporated and stop early enough that paint is set before the evening temperature drop.

How windy is too windy to paint outside?

Sustained winds above about 15 mph make brushing and rolling risky: paint skins before it levels, lap marks multiply, and dust or pollen embeds in the wet film. Spraying is far more sensitive — overspray drifts onto cars and neighbors above roughly 5 to 10 mph. Wind also accelerates drying, shortening your wet edge, so pick calm mornings for large walls.

Why is my fresh exterior paint blistering?

Heat blisters form when paint is applied to siding baking in direct sun — the surface skins over, then trapped solvent or water vaporizes underneath. Moisture blisters appear when paint goes over damp wood or when interior moisture pushes outward. Paint shaded sides, keep surfaces under about 90°F, and let rain-soaked siding dry a day or two before coating.

Exterior Painting glossary

Dew point spread
The gap between air temperature and dew point; painting standards call for surfaces at least 5°F above the dew point to prevent invisible condensation under fresh paint.
Surfactant leaching
Sticky brown or glossy streaks that surface when latex paint dries in cool, damp conditions; usually cosmetic and rinses off after the paint fully cures.
Wet edge
Keeping the boundary of just-applied paint wet so the next stroke blends invisibly; heat, wind, and low humidity shorten it and cause lap marks.
Surface temperature
The actual temperature of siding, which can run 20 to 40°F above air temperature in direct sun; paint labels' limits apply to the surface, not the forecast.
Full cure
The point when paint reaches final hardness and washability — typically 2 to 4 weeks for exterior acrylics — distinct from dry-to-touch, which takes only hours.
Blocking
Fresh paint sticking to itself where surfaces touch, like doors against jambs; worst in heat and humidity before the film fully cures.
