Weather in Belfast 10 Days – Unsettled with Frequent Showers

Those planning activities in Belfast over the coming week face an unsettled forecast dominated by cloud cover, frequent rain showers, and mild temperatures ranging from 6°C to 15°C. Multiple meteorological sources confirm that the city will experience typical autumn weather patterns, with precipitation risks remaining elevated through the next ten days.

The forecast draws from data provided by the UK’s Met Office, Ireland’s Met Éireann, and WeatherBug, offering residents and visitors a comprehensive view of what to expect. While conditions are expected to remain generally mild for the time of year, the combination of rainfall and wind gusts reaching up to 30mph will make outdoor planning challenging on several days.

Temperature variations throughout the period show highs reaching 14°C during afternoon hours, while overnight lows dip to around 6°C. The “feels like” temperature often falls several degrees below actual readings due to wind chill, particularly during the morning and evening hours when gusty conditions prevail. For those planning travel across Northern Ireland, current conditions across the region show similar patterns to the city.

What is the 10-day weather forecast for Belfast?

Key insights from the forecast data reveal several consistent patterns across multiple sources. The weather shows no extended dry spells, with rain probability consistently remaining above 20% throughout the period. Temperature swings between day and night remain moderate, rarely exceeding an 8-degree differential.

• High precipitation risk dominates the first 48 hours, with hourly readings showing 80-95% rain probability during peak periods
• Wind direction shifts between south, southeast, and southwest at speeds of 3-14mph, contributing to the unsettled conditions
• Temperatures range from 6°C overnight to 14°C during afternoon peaks, representing mild autumn weather for Northern Ireland
• Met Éireann forecasts heavier rainfall for western and southwestern areas during evening hours today
• Thursday brings the possibility of thundery showers with hail risk, particularly in western regions
• The weekend shows slight improvement with reduced precipitation percentages compared to midweek

Hourly weather details for Belfast over the next 10 days?

Wednesday hourly breakdown

The Met Office provides detailed hourly projections for today, showing a particularly wet morning and evening rush hour. Rain probability peaks at 95% during the 8am and 9am slots, gradually decreasing through midday before rising again to 95% at 5pm. Temperature progression shows a steady climb from 10°C at 7am to 14°C by 2pm and 3pm.

Wind gusts reaching 30mph from the south accompany the rainfall, creating challenging conditions for cyclists and pedestrians. The “feels like” temperature of 8°C during the morning hours drops below actual readings, emphasising the need for warm, waterproof clothing when travelling during peak commute times.

Thursday through the weekend

Thursday marks a transition in the weather pattern. According to Met Office hourly data, overnight temperatures hold steady at 6°C, with morning readings climbing to 7°C by 7am. Precipitation probability drops significantly to 10-20% during morning hours before rising to 30% in the afternoon. Southwesterly winds of 12-14mph maintain a breeze throughout the day.

Met Éireann offers a slightly different perspective, suggesting that rain and drizzle will clear northeastward during the morning, giving way to sunny spells and scattered heavy showers in the afternoon. Their forecast highlights the potential for thundery activity and hail, particularly in western areas, with temperatures reaching 15°C in some parts of Belfast.

Next week outlook

WeatherBug’s 10-day outlook indicates that unsettled conditions persist through Tuesday, with mostly cloudy skies and continued rain chances ranging from 30-60%. High temperatures gradually decline from 56°F (13°C) early in the period to 54°F (12°C) by the following Wednesday. Overnight lows remain consistent at 45-47°F (7-8°C).

Wind patterns through the extended period show predominantly southerly and southwesterly flows, occasionally shifting to southeasterly directions. Speeds fluctuate between 3mph during calmer periods and 14mph during more active phases, suggesting variable conditions rather than prolonged windy spells.

Weather in Belfast today and tomorrow?

Today’s conditions

Today brings a dull, damp start to Wednesday across Belfast and surrounding areas. Met Éireann’s Belfast forecast confirms persistent rain and drizzle throughout the morning hours, with mist and fog patches developing in some locations. Temperatures hover between 10°C and 14°C, while gusty southeast to south winds add to the chill factor.

The afternoon may offer slight improvement, with Met Office projections showing precipitation dropping to 60-70% between 1pm and 4pm. However, heavier rain is expected to return during the evening, particularly affecting western and southwestern districts. Residents should prepare for a wet commute home, with temperatures falling back to around 10°C by 10pm.

Tomorrow’s forecast

Thursday presents a more promising picture, though not entirely dry. Morning fog and lingering drizzle should clear northeastward during the late morning hours, allowing for some sunny intervals. The afternoon brings scattered showers, some potentially heavy and thundery with hail risk, especially in western areas outside the immediate city centre.

Temperature expectations for tomorrow range from 6°C overnight to 15°C during the warmest part of the day, making it slightly warmer than today overall. South to southwest winds will be noticeable but not severe, ranging from 10-14mph.

Extended forecasts: 15-day and 21-day outlook for Belfast?

Beyond the 10-day horizon

Detailed forecasts beyond 10 days become increasingly uncertain, reflecting the inherent limitations of meteorological prediction over extended timeframes. The Met Office’s Northern Ireland regional forecast extends to 5 days with reasonable confidence, while their national 28-day outlook provides only general trends rather than specific daily predictions. Those interested in seasonal trends for the UK and Ireland can find broader guidance through national meteorological services.

The Weather Outlook offers a 16-day view for Belfast, suggesting continued unsettled conditions with risks of frost and wind. Ground frost may develop where temperatures drop to 0-4°C during clear overnight periods, particularly in rural areas surrounding the city.

Long-range reliability

Meteorologists generally agree that forecasts beyond two weeks carry significant uncertainty. While general patterns may indicate above or below-average rainfall or temperatures, specific daily conditions cannot be reliably predicted. The current atmospheric setup suggests no immediate shift toward prolonged dry or cold spells.

Those seeking extended forecasts should understand that precipitation probability ranges widen considerably beyond 10 days, and what begins as a 30% chance of rain may increase or decrease substantially as the actual date approaches. The unsettled Atlantic pattern currently affecting Northern Ireland shows no signs of complete disruption in available longer-range guidance.

Day-by-day forecast progression

The following timeline summarises the expected conditions across Belfast, based on consensus from multiple sources including the Met Office, Met Éireann, and WeatherBug:
