Garden Sunlight Calculator

Garden Sunlight Calculator

Understand how much sun a garden is likely to receive before you book a viewing. Seasonal sunlight, morning versus evening, and the factors that direction alone does not reveal.

Why sunlight matters when researching a property

Garden direction tells you which way a garden faces. Sunlight tells you what that actually means in practice throughout the day and the year. A south facing garden in a narrow terrace with a two-storey extension on the southern boundary may receive significantly less sun than a west facing garden in a wide open plot. Direction is the starting point. Sunlight is the reality.

UK buyers consistently rank garden quality as one of the most important factors in a property purchase, yet most listings say nothing about how sunny a garden actually is. An estate agent who describes a garden as sunny may have visited on a bright August morning. The experience in November, or at 4pm on a January afternoon, can be completely different.

Checking sunlight before a viewing means you arrive knowing what to expect rather than discovering after an offer that the outdoor space you valued is in shadow for most of the year.

South Facing Garden includes a Sun Tracker in every property report. It estimates sunlight hours by season based on the garden's orientation and the property's precise coordinates, giving you a practical picture of the garden's light before you make the journey.

How seasonal changes affect garden sunlight

The UK sits at a latitude where seasonal variation in daylight and sun angle is significant. In June, the sun rises early, climbs high in the sky, and sets late. Gardens that feel bright and warm in summer may receive only a few hours of low winter sun between October and February.

This seasonal difference matters most for north and east facing gardens. A north facing garden may receive some direct sunlight in the early morning or late evening during the longest summer days, giving an impression of reasonable light during a summer viewing. The same garden in January may receive no direct sunlight at all, as the low winter sun never clears the roofline of the house.

South and west facing gardens tend to perform more consistently across the seasons, because the sun's path across the southern and western sky means these gardens are not blocked by the house itself.

The Sun Tracker in South Facing Garden shows estimated sunlight by season, not just as a single annual figure, so you can understand how the garden performs in winter as well as summer before you arrange a viewing. You can read more about how direction is determined in the Garden Direction Checker.

Morning sun versus afternoon and evening sun

The time of day a garden receives its sunlight matters as much as the total hours. Morning sun is gentler and comes from the east. It is ideal for people who spend time in the garden early in the day, work from home in a garden office, or grow plants that prefer cooler conditions.

Afternoon and evening sun comes from the south and west. It is warmer and more intense in summer, making it the preferred option for outdoor dining, entertaining, and general leisure use. Most people who have a preference for garden sunlight want afternoon and evening sun, which is why west and south facing gardens are consistently more popular.

An east facing garden that feels bright and pleasant during a morning viewing may feel cold and shaded when you actually want to use it after work. Knowing which part of the day a garden receives its sun helps you judge whether it suits your lifestyle before committing to a viewing or an offer.

Why direction alone does not tell the whole story

Garden direction is the single most important factor in determining sunlight, but it is not the only one. Two properties with identical south facing gardens on the same street can receive meaningfully different amounts of sun depending on what surrounds them.

A tall fence or wall on the southern boundary reduces winter sunlight significantly, because the low winter sun cannot clear it. A two-storey extension on the neighbouring property can cast a shadow across the garden in the afternoon. Mature trees on the southern boundary, particularly evergreens, reduce sunlight year-round. A narrow plot between tall terraces may be in shadow for much of the day even if it technically faces south.

South Facing Garden uses the property's specific geographic coordinates and garden orientation to estimate sunlight. This accounts for the sun's angle at that location throughout the year. Factors such as neighbouring buildings, fences and trees are not captured in the estimate, which is why we recommend using the Sun Tracker as a starting point for your research and assessing physical shading when you visit the property.

How the Sun Tracker works

When you search an address in South Facing Garden, the report includes a Sun Tracker that shows how the sun moves relative to the garden throughout the day and across the seasons. It uses the garden's orientation from the property boundary analysis alongside the latitude and longitude of the property to calculate the sun's position at different times of year.

The result is a visual representation of where the sun is at different hours and months, letting you see at a glance whether the garden receives morning sun, afternoon sun or all-day sun in June, and how that compares to the position in December. This is more useful than a single direction label because it shows you the practical reality of light in that garden across the year.

The Sun Tracker works alongside the Garden Direction Checker as part of the same property report. Both are included in every free search, alongside flood risk, broadband, schools, crime, EPC and more. You can read about the full range of checks on the Property Check Before Viewing page.

Example

Two properties, same street, different sunlight. Property A has a south facing garden with an open aspect. The Sun Tracker shows direct sunlight from around 9am to 5pm in March, extending to 6pm in June. Property B has a south facing garden but with a two-storey extension on the western boundary. The extension casts a shadow from mid-afternoon onwards. A buyer who only checked the direction would see both as south facing. The Sun Tracker and a careful viewing would reveal the difference.

Please note: Sunlight estimates from South Facing Garden are based on garden orientation and geographic coordinates. They do not account for neighbouring buildings, trees, fences or local obstructions. Always assess physical shading during a viewing, ideally at the time of day you would most want to use the garden.

Frequently asked questions

South Facing Garden includes a Sun Tracker for every UK property address. Enter the address and the report shows estimated sunlight hours by season, based on the garden's orientation, the property's geographic coordinates, and the angle of the sun at that location throughout the year. It is the most practical way to understand a garden's sunlight before arranging a viewing.
Direction is the starting point but not the whole story. A south facing garden will generally receive the most sunlight, but a tall fence on the southern boundary, a neighbouring property blocking the low winter sun, or a garden that is narrow and enclosed can all reduce actual sunlight significantly. South Facing Garden uses the property's specific coordinates and orientation to estimate sunlight rather than relying on direction alone.
In the UK, a south facing garden with no significant shading can receive direct sunlight for roughly 14 to 16 hours on the longest summer days, and 6 to 8 hours on clear winter days. In spring and autumn the figure sits between these extremes. A north facing garden may receive almost no direct sunlight in winter. These figures vary by latitude: gardens in Scotland receive longer summer days but lower sun angles than gardens in the south of England.
Morning sun comes from the east and is generally softer and cooler. Evening sun comes from the west and tends to be warmer and more intense in summer. An east facing garden is bright at breakfast but shaded by the afternoon. A west facing garden is shaded in the morning but warm from mid afternoon into the evening. South facing gardens receive both morning and evening sun as the sun arcs across the sky to the south.
The angle of the sun changes throughout the year. In summer the sun is high in the sky, so even gardens with tall fences or neighbouring buildings receive reasonable light. In winter the sun is low, meaning it can be blocked by obstacles that cause no issue in summer. A garden that feels sunny during a spring viewing may be substantially shadier in winter. Understanding seasonal variation before buying is one of the main reasons the Sun Tracker is useful.
No. South Facing Garden estimates sunlight based on garden orientation and geographic coordinates. Actual sunlight at a specific property depends on factors including neighbouring buildings, trees, fences, local topography and weather. The information is a research tool to help you ask the right questions before and during a viewing, not a precise measurement of guaranteed sunlight hours.
