What’s the forecast for today?
The live forecast above gives you the current temperature, chance of rain and wind for Glossodia. The Bureau of Meteorology issues official observations and seven-day outlooks. Afternoon sea breezes from the coast rarely reach this far inland, so the heat can build quickly in summer. Overnight lows in winter are crisp, often with frost in the surrounding paddocks.
What factors affect Glossodia’s weather?
Glossodia sits near the foothills of the Blue Mountains, about 75 kilometres west of Sydney. That inland position means less maritime moderation than you get with Sydney weather. Cold fronts sweeping across the ranges can bring sharp temperature drops and gusty winds. During La Niña events, the area tends to receive above-average rain; El Niño brings drier, hotter conditions.
Will it be hotter in Glossodia than Penrith?
Glossodia and Penrith weather are very similar because they’re only about 10 kilometres apart. Both sit inland and experience the same western Sydney heat effect. Check the live forecast above for the specific difference today.
When is the best time to visit Glossodia?
Spring (September–November) and autumn (March–May) offer milder days, with tops usually between 20°C and 25°C. Summer can be uncomfortably hot, and winter mornings are cold but often clear. If you’re planning outdoor activities, aim for a day with low humidity and no rain in the outlook.
Does Glossodia get bushfire weather alerts?
