Sydney CBD Weather: 10-Day Forecast, Hourly & Radar

Sydney’s reputation for wild weather swings isn’t just folklore—locals know that five minutes can mean the difference between sunshine and a sudden downpour. If you’re planning a commute through the CBD or an afternoon by the harbour, knowing what’s actually coming matters. Here’s where the official data from the Bureau of Meteorology comes in: today, 20 April, Sydney is sitting at 20° to 22° under mostly clear skies. The city hasn’t needed any active weather warnings, and the next few days look settled rather than dramatic. This guide cuts through the noise to give you the reliable forecasts you can actually plan around.

Sydney CBD weather 14 days

Two weeks of forecasting for an urban location like the CBD involves significant uncertainty. Australian meteorologists often describe April conditions as transitional, with moisture patterns from the north gradually weakening while cold fronts remain infrequent. The Bureau of Meteorology releases extended outlooks, but these carry inherently lower confidence than short-term forecasts. Current 14-day trends from BOM suggest temperatures generally holding between 16° and 22°, with most days showing less than 30% chance of any rainfall. The pattern isn’t perfectly settled though — model runs have occasionally suggested a more active system around day 10–12, which would push rain chances up to 40–50%. Forecasters advise checking back every 24 hours for updates on any such shift.

Day-by-day breakdown

Five key data points, one pattern: extended forecasts consistently show mild overnight lows and comfortable daytime highs with no major heat events. The BOM accessible forecast for Sydney shows today at 20° to 22°, tomorrow 18° to 17°, and Wednesday settling at 17° to 16° (Bureau of Meteorology). By Friday 24 April, temperatures stabilize around 17°C, which aligns with the general pattern of consistent cool conditions. Saturday and Sunday follow similar trajectories with highs in the 19–21° range. Week two appears to maintain this baseline, with no extreme deviations forecast as of the latest model runs.

The pattern suggests temperatures will remain stable through late April with no major cold snaps or heat events developing.

Precipitation trends

Rainfall probability across the two-week window generally stays under 30% per hour, based on BOM detailed forecast data for the Sydney region (Bureau of Meteorology). Sunday 5 April showed morning chances at 10% and afternoon peaks at 30% during 10:00 AM and 1:00 PM. Monday 6 April had slightly lower probabilities at 10–20% overall, with just 5% in the afternoons. These figures suggest that any precipitation would be light and intermittent rather than sustained rainfall. The lack of any significant moisture fetch from either the Coral Sea or Southern Ocean indicates that heavy rain events are unlikely over the next fortnight.

Sydney CBD weather 10 day

A 10-day forecast offers reasonable accuracy for planning purposes while acknowledging the limits of meteorological modeling this far out. The Bureau of Meteorology provides an accessible 10-day temperature range for Sydney that metropolitan residents and visitors can reference with reasonable confidence. This window covers both the immediate week and the following weekend, giving commuters, event organizers, and tourists actionable information for their schedules.

Weekly summary

Four days, four distinct temperature readings, and one clear takeaway: the week ahead is cooler than average for late April. Today brings a high of 22°C, dropping to tomorrow’s 18°C and Wednesday’s 16°C. Thursday warms slightly to 21°C before Friday settles back at 20°C. This cooling trend reflects a southerly air mass nudging into the region, which BOM identifies in its Sydney metropolitan forecast updates (Bureau of Meteorology). Overnight lows range from 16° to 17°, meaning early morning CBD workers may want a light jacket. The Weatherzone hourly data confirms the evening temperatures track similarly, with Sydney at 9:00 PM on 20 April registering 18.3°C.

Chance of rain

Rain probability in the 10-day window remains low across most hours. The BOM detailed forecast data shows rainfall chances generally under 30% hourly for the Sydney CBD area (Bureau of Meteorology). Tuesday 31 March (representing similar forecast patterns) showed 5% chance at 8:00 AM rising to 30% by 11:00 AM, with only a 10% chance of more than 1mm. Wednesday 1 April had a 10% chance from 2:00 AM climbing to 30% at 11:00 AM and 2:00 PM. Thursday 2 April started at 10% from 2:00 AM and peaked at 30% at 11:00 AM. The pattern suggests that if rain occurs, it would be brief afternoon showers rather than all-day events. No significant weather warnings are active for the Sydney CBD region.

Sydney CBD weather tomorrow

Tomorrow’s weather in Sydney CBD is typically the most-searched forecast item, and for good reason—it directly affects tomorrow’s commute, clothing choices, and outdoor plans. The Bureau of Meteorology provides a specific accessible forecast for Sydney that gives residents the numbers they need to start their day prepared.

Morning forecast

Tomorrow morning in the CBD will start cool, around 17° to 18°, with partly cloudy skies. According to BOM, the forecast for 21 April is 18° to 17° (Bureau of Meteorology). Weatherzone hourly data shows Sydney at midnight on 21 April at 17.4°C, mostly clear, with a 20% rain chance. The morning hours should see temperatures climb from that overnight low toward the 18°C mark by mid-morning. Wind speeds remain light at around 10 km/h, making for comfortable conditions on exposed pedestrian areas like the Cahill Expressway walkway or the Botanic Gardens paths. No fog or reduced visibility is indicated in the significant weather section for Sydney (Bureau of Meteorology), so morning flights in and out of Sydney Airport should operate normally.

The cool start means morning commuters should layer up, but conditions should feel comfortable by mid-morning.

Evening outlook

Tomorrow evening will see temperatures falling back toward 17°C after the daytime high of 18°C. The Weatherzone forecast shows the 20 April evening at 18.3°C with 15% rain chance, and the pattern for 21 April should follow similarly. Skies will likely remain partly cloudy, and the light wind will persist. For those heading to evening events in the CBD—a theatre show, a restaurant dinner, or a late commute—the weather should cooperate without disruption. The UV index tomorrow afternoon will peak at 7, according to BOM data patterns for late April, so any outdoor activity before sunset should still consider sun protection.

Sydney CBD weather hourly

Hourly weather data fills the gap between “what’s happening right now” and “what’s the forecast for tomorrow afternoon.” The Bureau of Meteorology and Weatherzone both publish hourly forecasts for Sydney, covering temperature, rain probability, UV index, and atmospheric conditions in granular detail. This level of specificity is particularly valuable for outdoor workers, event coordinators, and anyone whose plans hinge on specific windows of time.

Afternoon updates

Today’s afternoon temperatures hover around 20° to 22°C in the CBD, with the BOM accessible forecast confirming the range (Bureau of Meteorology). The Weatherzone hourly data shows 9:00 PM on 20 April at 18.3°C, mostly clear, with a 15% rain chance. Afternoon rain probabilities in this pattern typically reach 30% around 11:00 AM to 2:00 PM, with a 10% chance of measurable rainfall exceeding 1mm. For workers on lunch breaks in Martin Place or visitors walking from Circular Quay to Darling Harbour, this means a very low likelihood of rain interruption. The wind stays manageable at 10 km/h, which won’t significantly affect cycling commutes along the Harbour Bridge approach or ferry services on Sydney Harbour.

Afternoon conditions remain stable with no weather systems disrupting harbour area activities.

Evening hourly

Evening temperatures in the CBD will drop from the afternoon high through the 19°C range by 6:00 PM, settling to around 17–18°C by 9:00 PM. BOM detailed forecast data includes mixing height information, showing overnight values dropping to just 25m—indicating stable air with minimal vertical mixing. This stable layer can trap any localized pollutants, which is relevant for residents near major roads like the Eastern Distributor ventilation stacks or construction sites in the QVB precinct. By midnight, temperatures will be around 17.4°C according to Weatherzone data for 21 April. The evening hours will be dry, with rain probability remaining under 20% throughout the night.

Sydney CBD weather radar

Weather radar provides real-time visualization of precipitation and storm systems, giving CBD residents immediate awareness of any approaching weather. The Bureau of Meteorology operates a network of radar stations across NSW, including coverage of the Sydney metropolitan area. Accessing live radar data allows residents to make last-minute decisions about outdoor activities, commute timing, or event modifications based on actual conditions rather than forecast predictions.

Live radar map

BOM provides live rain radar and weather maps for NSW including the Sydney CBD area (Bureau of Meteorology). The primary radar station serving the Sydney region is located at Woolgoolga, with supplementary coverage from the 128km radar at Terrey Hills. Together, these provide comprehensive precipitation tracking for the Sydney basin. The radar imagery updates every 6 to 12 minutes, giving near-real-time monitoring of any rain-bearing systems. Satellite imagery from BOM also complements radar data, showing cloud cover patterns that can indicate developing weather even before precipitation reaches radar-detectable levels. Weatherzone offers its own radar interpretation as well, providing an additional source for those wanting to cross-reference data.

Residents can access multiple radar perspectives to verify current conditions before making outdoor plans.

Precipitation movement

Rain-bearing systems in the Sydney region typically move from west to east, driven by the prevailing westerly flow that dominates NSW weather patterns. Current radar shows no significant precipitation heading toward the Sydney CBD (Bureau of Meteorology). The BOM detailed forecast data confirms no rain indicated in the significant weather for early forecast days, which aligns with the radar observation. For those checking radar before a morning ferry from Circular Quay or an early meeting in the CBD, the current pattern shows clear conditions with no weather fronts approaching from any direction. The mixing height data showing daytime values over 2000m indicates good vertical air movement, which helps disperse any localized moisture and maintains clear visibility on radar.

Active weather warnings

Checking for weather warnings is a critical step that many Sydney residents overlook until they’re caught in unexpected conditions. The Bureau of Meteorology issues warnings for severe thunderstorms, heavy rainfall, strong winds, and other hazardous weather affecting NSW. For the Sydney CBD, these warnings are particularly important during the summer storm season or when bushfire smoke drifts from surrounding areas. Understanding what warnings are in effect—or confirming there are none—gives residents the all-clear for their daily plans.

The Bureau of Meteorology’s confirmation of zero active warnings gives Sydney CBD workers and visitors the confidence to proceed with outdoor plans.

Sunrise, sunset, and UV index

Beyond temperature and rain, the UV index and daylight hours directly affect how Sydney CBD residents plan their day. Late April in Sydney means daylight saving time is ending, bringing sunrise to around 6:20 AM and sunset to approximately 5:30 PM. The UV index pattern peaks at 7 during early afternoon hours, which exceeds the threshold for “very high” exposure and requires active sun protection. This data point matters for anyone working outdoors—construction workers along George Street, delivery riders, or tourists walking between the Opera House and The Rocks.

Frequently asked questions

For Sydney CBD commuters and residents, the practical takeaway is straightforward: the weather over the next week and a half is set to be cool, dry, and largely uneventful by BOM standards. Daytime highs in the 17–22°C range will make for comfortable walking weather across the harbour foreshore, but the low UV index belies the need for sun protection in the afternoon. The lack of any active warnings means the Bureau of Meteorology sees nothing on the horizon that should disrupt the city’s rhythm. Check BOM’s radar before any outdoor event that depends on dry conditions, and layer up for early morning starts—that’s really all the preparation a typical CBD day requires. Residents and workers in the Sydney CBD can expect stable, predictable weather that won’t require major adjustments to daily routines.
