Seasonal Guide for Painting in Melbourne
Spring (September–November): A Top Choice
Spring brings mild temps and lower humidity—ideal conditions for both exterior and interior painting. Days between 10°C and 28°C ensure paint dries evenly and adheres properly.
- Key benefits: Stable weather, low dew, and good daylight
- Watch-out: Occasional spring rain may interrupt outdoor plans
- Time of day: Painting between 10 am–3 pm avoids morning dew and evening chill
Autumn (March–May): Another Ideal Window
Autumn mirrors spring in weather stability—cool but not cold, and mostly dry. It’s perfect for high-quality finishes.
- ▶ Ideal temperature: 10°C–25°C
- ▶ Plus: Less UV strain on freshly painted surfaces
Summer (December–February): Proceed with Caution
Summer has low rain but can feature heat spikes and high UV—‘flash-drying’ paint, leading to cracks.
- Best to paint early morning (7–9 am) or late afternoon
- Avoid peak heat (>30°C) or humidity (>70%)
Winter (June–August): Least Recommended
Winter’s cool, damp days slow drying and can trap moisture, causing poor paint adhesion.
- Only paint if daytime temps stay above 10°C, using low-VOC or oil-based paints in well-heated spaces
Climate Factors That Matter
Temperature
Most paints require 10–30 °C for proper curing. Outside this range? Expect cracking or peeling .
Humidity
High humidity (>70%) slows drying, invites mould, and causes blistering. Aim for 40–70% humidity .
Wind & Rain
Dry weather windows are key. For exteriors, you need 3–4 dry days—avoid rain or heavy dew .
Time of Day
- 🌅 Morning (10 am–noon): Dew evaporated, mild sun
- ☀️ Midday: Can dry too fast if hot
- 🌇 Late afternoon: Safe before evening dew settles
Preparing for a Successful Paint Project
Surface Prep
Clean walls, remove mildew, fill cracks. Good prep ensures paint bonds—and lasts.
Primer & Paint Selection
Use primers for porous surfaces. For exteriors, choose weather-proof and UV-resistant paints.
Tools & Equipment
High-quality brushes, rollers, or sprayers yield smoother finishes. Use drop sheets and safety gear for exteriors.
Monitor the Forecast
Check daily weather and scale your timing to secure a dry window with stable conditions .
Pro Tips for Variable Weather
- Be flexible: Stop painting if weather shifts — better to pause than risk a ruined finish
- Avoid direct sunlight: Paint in shaded areas to prevent rapid drying
- Add a sealant: A clear protective coat helps resist Melbourne’s UV and rain
- Stay safe: Secure equipment—wind or sudden gusts are not to be underestimated
