Precip mm
Expected rainfall or snowfall in mm per hour. Even light drizzle meaningfully reduces felt temperature when combined with wind.
Soil °C surface
Temperature of the soil at the surface (0 cm depth). Most seeds germinate above 7–10 °C. Useful for sowing decisions and frost assessment.
Soil °C 6 cm
Soil temperature at 6 cm depth — the root zone for many crops and seedlings. Lags behind the surface by several hours.

Soil moisture
Volumetric water content of the top 1 cm of soil in m³/m³. Above 0.4 indicates saturated ground; below 0.2 is dry. Useful for assessing whether ground is workable, and for motorhome or caravan pitch suitability.

Soil moisture
Water saturation of the top 1 cm of soil as a percentage. Above 40% indicates saturated ground; below 20% is dry. Useful for assessing whether ground is workable, and for motorhome or caravan pitch suitability.
Concrete °C
Estimated temperature of sun-exposed urban paving. Concrete absorbs more solar energy than grass and cannot cool itself through evaporation — surface temps can run 15–25 °C above air temperature on sunny days.
Vehicle °C
Estimated ambient cabin temperature inside a sealed, parked vehicle — adjusted for your chosen vehicle type. Values above 35 °C are dangerous for children and pets; above 45 °C potentially fatal within minutes.
Indoors °C
Estimated temperature inside a building with windows closed and no active cooling. Select your building type from the dropdown — brick, modern insulated, Victorian terrace, stone cottage, timber frame, top-floor flat, or conservatory. Each type has its own insulation, retained warmth, thermal mass, and glazing characteristics. Indoor peak typically lags the outdoor peak by 2–4 hours due to thermal mass.

SunScope's soil moisture column shows the volumetric water content of the top centimetre of soil in m³/m³. A reading above 0.4 indicates saturated ground where a heavy vehicle is likely to sink or churn the surface. Below 0.2 is dry and firm. The Vehicle profile includes soil moisture by default precisely for motorhome and caravan users who need to assess pitch suitability before arriving on site.
