Weather Outlook
The biggest wildcard for any eclipse is the weather. A cloudy sky can obscure the view entirely. Here's what historical data tells us about Sydney's chances in late July — and what you can do to improve your odds.
Sydney in July — Climate Overview
July is the middle of Sydney's winter. While it's mild by global standards, it's Sydney's coldest and one of its cloudier months. Here are the key historical averages for late July:

Cloud Cover Analysis
Clear sky probability for Sydney on a July afternoon
40–50%

This is lower than ideal for eclipse viewing, but still gives reasonable odds — and it's better than many other locations along the eclipse path.
Key factors for July 22, 2028:
- Cold fronts: The main source of cloud and rain in Sydney during winter. Fronts typically pass through every few days, bringing 1-2 days of cloud followed by clearing.
- Afternoon timing: Totality is at 2:01 PM, which is favourable — morning fog and low cloud typically burns off by midday even in winter.
- High-pressure systems: When a high-pressure system sits over Sydney, skies are typically clear and stable. The days between fronts are often ideal.
What If It's Cloudy?
Even under overcast skies, you'll still experience some of the eclipse's effects — the dramatic darkening during totality is visible regardless of cloud cover. However, you won't see the corona, diamond ring, or other visual highlights.
If forecasts show persistent cloud for Sydney, consider these backup strategies:
Head Inland
Areas west of the Great Dividing Range (e.g., Dubbo, Mudgee) typically have clearer skies in winter. The eclipse path covers these areas too.
Head North
The eclipse path continues north through Queensland. Southeast Queensland generally has better winter weather than Sydney.
Find Sucker Holes
Experienced eclipse chasers watch satellite imagery on the day and drive to gaps in the cloud. Even a brief clearing during totality is enough.
Embrace the Clouds
Thin or broken cloud can actually enhance the experience. The corona shining through gaps, dramatic sky colours, and the sudden darkness are all spectacular.
How Does Sydney Compare?
The eclipse path crosses the Australian continent from northwest to southeast. Different locations along the path have different weather profiles:
| Location | Clear Sky Probability | Totality Duration | Notes |
|---|---|---|---|
| Kimberley, WA | ~75% | ~5 min | Best weather, most remote |
| Alice Springs area | ~70% | ~4 min | Dry climate, clear skies |
| Inland NSW (Dubbo) | ~55% | ~3.5 min | Good backup option |
| Sydney | ~45% | ~3 min 50s | Largest city on the path |
| Blue Mountains | ~40% | ~3.5 min | Higher altitude = more fog risk |
Weather Tips
- Start monitoring long-range forecasts from about 2 weeks before the eclipse — this is when forecasts become reasonably reliable
- Check satellite imagery on the morning of the eclipse for real-time cloud positions
- The BOM's 7-day forecast for Sydney is updated daily and available at bom.gov.au
- Dress warmly — it's winter. Layers, a warm jacket, and a beanie are essential, especially if you're standing outdoors for several hours
- Even on a clear day, wind chill can make it feel much colder during the temperature drop of totality
