Chance = odds of rain heavy enough to threaten a fresh painting job, across the work + cure window. High risk is our call, not a rule — the odds of a redo are real, so we'd wait; caution means it's workable with care. Either way it's your crew, so check the sky and radar before you commit.
This is today's snapshot. The next 7 days for your exact ZIP — with the reasons behind every caution and stop, refreshed each morning — are what the free Sunday brief delivers.

Air-temperature forecast logic — verify surface conditions on site.
What the temperature means for painting tomorrow
Tomorrow runs about 4° warmer than a typical July (87° vs a 83° normal), so a fresh coat flashes and sets faster — a shorter dry window is enough to cure. Temperature aside, it's rain and wind that decide the call tomorrow — see the breakdown above.

What controls a painting day in Oʻahu
Around Oʻahu, exterior painting runs a year-round window with a wetter winter stretch — the area sees year-round trade-wind warmth, wetter in winter, with windward showers that often skip leeward. But the call rarely comes down to the calendar: it's the morning and evening dew-point spread and the next rain that decide any given day.
These thresholds come from the manufacturers and standards cited above — the physics is the same anywhere. What's specific to Oʻahu is when they line up, which is exactly what the live area-by-area call at the top of this page tracks each day.
When painting gets tricky in Oʻahu
Rain stays fairly steady month to month here, so a paintingday comes down to the daily cure window and which part of the metro you're in more than the season. Temperatures here stay above the 40°F paintingminimum year-round, so it's rain — not cold — that sets the calendar. Source ≈10-yr ERA5 reanalysis (Open-Meteo), 2015–2024
Common questions
Can you paint outside below 40°F in Oʻahu?
Most exterior latex/acrylic paints need about 40°F and rising to cure, though a few Sherwin-Williams products are rated to 35°F. Below the product's published minimum the film won't form properly. Check the specific product's technical data sheet before applying.
How close to the dew point is too close to paint in Oʻahu?
Manufacturers — Sherwin-Williams Duration, Behr, PPG, and Benjamin Moore — require the surface to stay at least 5°F above the dew point. Within that margin, condensation can form under the coat and wreck adhesion. Our daily call checks this against the local forecast.
How long before rain can you paint in Oʻahu?
A fresh coat needs dry weather through its cure window — plan for several hours, and up to 24–48 hours in cool conditions per the manufacturer data sheets, with no rain after application. In Oʻahu, year-round trade-wind warmth, wetter in winter, with windward showers that often skip leeward makes that window the thing to watch.
