<tr><td><strong>Air °C</strong></td><td>Standard air temperature at 2 m above ground — the thermometer reading. Does not account for sun, wind, or humidity.</td></tr>
<tr><td><strong>Shade Air °C</strong></td><td>Estimated air temperature sitting in the typical shade of the selected Solar Model — building shadow, beach umbrella, tree canopy, boat panels, and so on. Sheltered, sun-warmed surroundings push it above the official open-ground Air figure on calm sunny hours; wind and cloud pull it back toward it. An estimate, not a measurement, and different from the standardised 2 m Air reading.</td></tr>
<tr><td><strong>RH %</strong></td><td>Relative humidity: how much moisture the air holds as a percentage of its maximum capacity at that temperature. High RH makes warm days feel stickier and cold days feel rawer.</td></tr>
<tr><td><strong>Dew Point</strong></td><td>The temperature at which air becomes saturated and moisture begins to condense. Above 16 °C it starts to feel muggy; above 21 °C it feels oppressive. A better measure of absolute humidity than RH.</td></tr>
<tr><td><strong>Wind</strong></td><td>Mean wind speed at 10 m in mph, with peak gust in brackets where significantly higher. Gust colour follows the Beaufort scale: amber = Near Gale (32+ mph), orange = Gale (39+ mph), red = Severe Gale or above (55+ mph). Event alerts classify conditions from Strong Breeze through to Violent Storm. Wind is the primary driver of wind chill.</td></tr>

<tr><td><strong>UV-B</strong></td><td>Estimated UV-B radiation index. Causes sunburn and drives vitamin D production. Intensity depends strongly on solar elevation and cloud cover, falling sharply at low sun angles.</td></tr>
<tr><td><strong>Burn time</strong></td><td>Estimated time to reach one Minimal Erythemal Dose (MED) — the threshold for sunburn — based on the UV index and your selected Fitzpatrick skin type (chosen from a dropdown in the column bar). A guide, not a medical measurement.</td></tr>
<tr><td><strong>SunSoak °C</strong></td><td>SunScope's signature felt-temperature index. Starts from UTCI then adds three layers: a rain and snow penalty (wet clothing can drop felt temperature by up to 8 °C), a Solar Model for where you actually are (forest, alpine, beach, river, open water, desert), and full mean radiant temperature from surrounding surfaces. The most honest single answer to: what will it actually feel like out there?</td></tr>
<tr><td><strong>Shade °C felt</strong></td><td>SunSoak with the sun taken away — the felt temperature standing in the typical shade of the selected Solar Model (building shadow, beach umbrella, tree canopy, boat panels, and so on). You are still outdoors, so wind, humidity and rain affect you exactly as they do in the open; only the direct beam and part of the sky are blocked. Expect several degrees below SunSoak in daytime sun, and near-identical readings after dark, when there is no sun to stand out of.</td></tr>
<tr><td><strong>Precip mm</strong></td><td>Expected rainfall in mm per hour; snowfall is shown in cm. Even light drizzle meaningfully reduces felt temperature when combined with wind.</td></tr>
<tr><td><strong>Rain %</strong></td><td>Probability of precipitation for this hour (0100%), derived from Open-Meteo ensemble model runs. A high value means rain is likely even if the expected rate is low — useful for spotting showers the deterministic forecast may miss.</td></tr>
<tr><td><strong>Lightning</strong></td><td>Lightning Potential Index (LPI) from Open-Meteo in J/kg — a convective energy index. Values above 5 suggest moderate lightning risk, above 25 suggest high risk.</td></tr>

<tr><td><strong>Managed °C</strong></td><td>The same building model with two interventions: curtains closed by day to block solar gain, and windows opened whenever outdoor air is cooler than inside — the standard UK heatwave advice. Toggle with the Managed tick next to the building dropdown.</td></tr>
<tr><td><strong>Fur Temp °C</strong></td><td>Estimated fur surface temperature a cat or small dog experiences in direct sun, calibrated for a thin/short coat. Choose your pet's fur colour — Black/Dark, Brown/Tabby, Golden/Tan, or White/Pale — from the dropdown; darker coats absorb more solar heat and run hotter.</td></tr>
<tr><td><strong>Paw Temp °C</strong></td><td>Estimated ground/pavement surface temperature for paw contact, colour-coded by burn risk: green below 40 °C (safe), amber 4052 °C (discomfort or possible burn on prolonged contact), red above 52 °C (can burn within 60 seconds). If you can't hold the back of your hand on the surface for 7 seconds, it's too hot to walk your pet.</td></tr>
<tr><td><strong>Pet Shade °C</strong></td><td>Shaded air temperature for a resting pet, using the same shade estimate as Shade Air but with a lower, pet-specific alert threshold — small pets have far less capacity to dump heat than humans.</td></tr>
<tr><td><strong>Pet Shade °C</strong></td><td>Shaded air temperature for a resting pet, using the same shade microclimate model as the Shade column but kept as an air temperature and with a lower, pet-specific alert threshold — small pets have far less capacity to dump heat than humans.</td></tr>
<tr><td><strong>Pet Home °C</strong></td><td>Indoor temperature estimate for a pet left home alone, using the same model as the Indoors column but with a lower, pet-specific alert threshold (26 °C) rather than the human heatwave guidance threshold.</td></tr>
<tr><td><strong>Visibility km</strong></td><td>Horizontal visibility in kilometres, sourced from the Copernicus CAMS air quality model. Below 1 km indicates fog or very thick haze; below 10 km suggests mist, smoke, or significant pollution. Relevant for driving, flying, cycling, and photography.</td></tr>
<tr><td><strong>AQI</strong></td><td>European Air Quality Index (0100+), combining PM2.5, PM10, ozone, nitrogen dioxide, and sulphur dioxide. 020 = Good; 2040 = Fair; 4060 = Moderate; 6080 = Poor; 80100 = Very Poor; 100+ = Extremely Poor. Sourced from Copernicus CAMS.</td></tr>
