{"@type":"Question","name":"What is UTCI and why is it more accurate than feels-like temperature?","acceptedAnswer":{"@type":"Answer","text":"UTCI stands for Universal Thermal Climate Index. Unlike a standard feels-like temperature which usually only adjusts for wind chill or humidity on their own, UTCI uses a full physiological model of the human body. It combines four factors at once: air temperature, humidity, wind speed, and the heat from solar radiation hitting your skin. On a sunny day the sun can make you feel 10-15 degrees warmer than the air temperature alone, and most weather apps ignore this entirely. UTCI is a peer-reviewed scientific standard used in public health systems across Europe."}},
{"@type":"Question","name":"What is SunSoak and how is it different from UTCI?","acceptedAnswer":{"@type":"Answer","text":"SunSoak is SunScope's signature felt-temperature index. It starts from UTCI - the biometeorological standard - and adds three extra layers: a rain and snow penalty reflecting the chill of wet clothing (heavy rain plus strong wind can drop felt temperature by 7-8 degrees); an environment modifier adjusting the solar load for where you actually are (forest canopy, alpine altitude, beach glare, shaded riverbank, desert ground heat); and mean radiant temperature from all surrounding surfaces. On a dry day in open conditions SunSoak and UTCI are very similar. In rain, shade, altitude, or at the coast they can differ significantly."}},

It starts from UTCI - the biometeorological standard - and adds three extra layers: a rain and snow penalty reflecting the chill of wet clothing (heavy rain plus strong wind can drop felt temperature by 7-8 degrees); a Solar Model adjusting the solar load for where you actually are, chosen from eight settings (grass/open field, town/city, beach/lakeside, river/riverbank, forest/woodland, open water, alpine altitude, desert/arid); and mean radiant temperature from all surrounding surfaces. On a dry day in open conditions SunSoak and UTCI are very similar. In rain, shade, altitude, or at the coast they can differ significantly."}},
{"@type":"Question","name":"What is the difference between UTCI and heat index?","acceptedAnswer":{"@type":"Answer","text":"Heat index is a simple table-based formula that adjusts air temperature for humidity only - it ignores wind and solar radiation entirely. UTCI is a full physiological model accounting for air temperature, humidity, wind speed, and mean radiant temperature from solar radiation. In sunny or windy conditions the two values can differ by 10-20 degrees. UTCI is the standard used in European heat-health warning systems."}},
{"@type":"Question","name":"Why does SunScope sometimes show a much higher temperature than my regular weather app?","acceptedAnswer":{"@type":"Answer","text":"On clear sunny days, direct solar radiation heats your skin significantly - sometimes adding 10 degrees or more to what the air temperature alone would suggest. SunScope calculates mean radiant temperature from real shortwave radiation forecast data. Standard weather apps ignore solar radiation entirely and only report air temperature or basic wind chill."}},
{"@type":"Question","name":"Why does SunScope sometimes show a lower temperature than my regular weather app?","acceptedAnswer":{"@type":"Answer","text":"Wind chill and precipitation both reduce felt temperature. If it is raining or blustery, the SunSoak value will be noticeably lower than the thermometer reading. A 15 degree day with heavy rain and a strong wind can feel closer to 8 or 9 degrees. SunScope captures this; most apps do not."}},
{"@type":"Question","name":"How do I read the SunScope table?","acceptedAnswer":{"@type":"Answer","text":"Each row is one hour of the day. The most important column is SunSoak - the felt temperature accounting for all weather factors combined. Colour coding tells you comfort at a glance: blue means cold, green means comfortable, yellow and orange mean warm or hot, red means dangerous heat stress. Switch between profiles using the buttons and dropdowns above the table - Basic, Home, Vehicle, then Places and Activities dropdowns for location and activity-specific views. Hover any column header for a plain-language description of what it shows."}},
{"@type":"Question","name":"What do the different profiles and dropdowns show?","acceptedAnswer":{"@type":"Answer","text":"Each profile is a curated set of columns. Basic shows core weather: felt temperature, sky, wind, rain. Home adds indoor building temperature. Vehicle adds car cabin temperature, soil moisture, and visibility. The Places dropdown offers Urban, Beach, Events, Park, Airport (free) plus Festival and Construction (Extra). The Activities dropdown offers Farming, Cycling, Running, and Dog Walking (free) plus Sailing, Winter Sports, Naturist, Hiking, Photography, and Fishing (Extra). Temps and Custom are Extra-only."}},

Your last searched location is remembered automatically the next time you visit."}},
{"@type":"Question","name":"What UV level is dangerous?","acceptedAnswer":{"@type":"Answer","text":"WHO UV index scale: 1-2 Low, no protection needed for short exposure. 3-5 Moderate, wear sunscreen and a hat for over 30 minutes outside. 6-7 High, seek shade during midday, apply SPF 30+. 8-10 Very High, minimise direct sun 11am-3pm. 11+ Extreme, avoid outdoor exposure during peak hours. In the UK, UV 6+ is common on clear summer days May-August."}},
{"@type":"Question","name":"How long until I get sunburn today?","acceptedAnswer":{"@type":"Answer","text":"It depends on the UV index and your skin type. SunScope shows a Burn time column estimating minutes to the sunburn threshold (one Minimal Erythemal Dose). At UV 8+, fair skin types I and II can burn in under 10 minutes. Medium skin types have around 20-25 minutes. Darker skin has more natural protection but is not immune. Burn time assumes no sunscreen and no shade."}},

{"@type":"Question","name":"Why does the sky display show the wrong time of day?","acceptedAnswer":{"@type":"Answer","text":"The sky scope shows current conditions only - the actual time right now, not the hour you are browsing in the table. The sun position, sky colour, and glow intensity are calculated from real solar elevation and radiation data for the current moment. If you are looking at a future hour in the forecast table, the sky display stays locked to now by design."}},

The forecast auto-refreshes every 5 minutes while the page is open so the current hour always reflects the latest data from Open-Meteo. No manual reload needed."}},
{"@type":"Question","name":"How accurate is SunScope?","acceptedAnswer":{"@type":"Answer","text":"SunScope uses Open-Meteo data from ECMWF and national meteorological services - the same models used by professional forecasters. The UTCI calculation follows the peer-reviewed Bröde 2012 polynomial exactly. Derived columns such as vehicle temperature, indoor temperature, and concrete surface are physics-based estimates that vary based on local factors like building construction, shading, and surface colour. Treat them as well-informed estimates rather than precise measurements."}},
