<h2>Forecast profiles</h2>
<p>
SunScope organises its columns into <strong>profiles</strong> — curated sets of data tailored
to different activities and use cases. Rather than showing every column at once, each profile
surfaces the information that actually matters for that situation. You can switch profiles
using the row of buttons above the forecast table, or switch to <strong>Custom</strong> to
pick individual columns yourself.
</p>
<div class="profile-block">
<p class="profile-name">🏙️ Urban</p>
<p>
Designed for anyone moving around a city on foot — commuting, shopping, sightseeing.
The urban environment creates its own microclimate: buildings channel wind into gusts down
narrow streets, concrete absorbs heat all day and radiates it back long after sunset, and
the lack of vegetation means there's no evaporative cooling. The Urban profile shows
<strong>air temperature</strong>, <strong>wind speed and direction</strong> (useful for
finding sheltered routes), <strong>cloud cover</strong>, <strong>UV-A index</strong> and
<strong>burn time</strong> for sun protection, <strong>UTCI+P</strong> for overall felt
comfort, <strong>precipitation</strong>, and <strong>concrete surface temperature</strong>
— the heat radiating up from pavement that standard forecasts completely ignore.
</p>
</div>
<div class="profile-block">
<p class="profile-name">🌾 Farming</p>
<p>
Built for anyone working the land — farmers, growers, and market gardeners. Decision-making
in agriculture is driven by conditions at ground level, not just the air. The Farming profile
shows <strong>air temperature</strong>, <strong>relative humidity</strong> and
<strong>dew point</strong> (critical for frost risk assessment and disease pressure on crops),
<strong>wind speed and direction</strong> (essential for safe spraying windows),
<strong>cloud cover</strong> and <strong>sun elevation</strong> for light levels,
<strong>UTCI</strong> for heat stress on the person working outdoors,
<strong>precipitation</strong>, and the three soil columns:
<strong>surface soil temperature</strong>, <strong>soil temperature at 6 cm</strong>
(the root zone for most seedlings), and <strong>soil moisture</strong> — so you know
whether the ground is workable or waterlogged before you head out.
</p>
</div>
<div class="profile-block">
<p class="profile-name">⛵ Sailing</p>
<p>
Wind is everything on the water, and the conditions out at sea can be dramatically different
from what the shore feels like. The Sailing profile leads with what matters most:
<strong>air temperature</strong> (hypothermia is a real risk — water conducts heat away from
the body twenty-five times faster than air), <strong>dew point</strong> (condensation on
sails and equipment is a practical concern at dawn and dusk), <strong>wind speed</strong>
with gusts, <strong>wind direction</strong>, <strong>cloud cover</strong>, and
<strong>sun elevation</strong> for visibility and glare. UV exposure is significantly higher
on open water due to reflection off the surface, so <strong>UV-A index</strong> and
<strong>burn time</strong> are included. <strong>UTCI+P</strong> captures the combined
misery of wet, windy conditions, and <strong>precipitation</strong> rounds out the picture
for passage planning.
</p>
</div>
<div class="profile-block">
<p class="profile-name">🚗 Vehicle</p>
<p>
Covers the parked and travelling vehicle experience — especially useful for anyone with
children or pets, motorhome travellers, and caravan owners. The headline column is
<strong>vehicle interior temperature</strong>: a physics-based estimate of how hot the
cabin gets when parked and sealed, adjusted for your chosen vehicle type (car, MPV, SUV,
motorhome, or caravan). <strong>Wind speed</strong> is included because it matters
significantly for high-sided vehicles and caravans. <strong>Cloud cover</strong> and
<strong>air temperature</strong> give context, <strong>precipitation</strong> covers
driving conditions, and <strong>UTCI+P</strong> tells you what it will feel like when
you step outside. <strong>Soil moisture</strong> is included specifically for motorhome
and caravan users — values above 0.4 m³/m³ indicate saturated ground where pitching
or manoeuvring is likely to cause problems.
</p>
</div>
<div class="profile-block">
<p class="profile-name">🏠 Home</p>
<p>
For managing indoor comfort without air conditioning — the typical UK home scenario.
The two indoor temperature columns are central: <strong>Indoors</strong> estimates the
ambient temperature inside a typical brick house with windows closed and no active cooling,
accounting for wall conduction, window solar gain, and thermal mass (indoor temperatures
usually peak 2–4 hours after the outdoor peak). <strong>Managed indoors</strong> shows
what you could achieve by following standard heatwave advice — closing curtains to block
direct solar gain and opening windows whenever the outdoor air is cooler than inside.
Supporting columns include <strong>air temperature</strong>, <strong>relative humidity</strong>
and <strong>dew point</strong> (important for condensation and mould risk in cooler months),
<strong>wind speed</strong> for ventilation decisions, <strong>cloud cover</strong>,
and <strong>precipitation</strong> — so you know whether to open the windows or bring
the washing in.
</p>
</div>
<h2>Column reference</h2>
<p>Every column in the SunScope forecast table is described below.</p>
<table class="stress-table col-ref-table">
<thead>
<tr><th>Column</th><th>What it shows</th></tr>
</thead>
<tbody>
<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>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, with peak gust in brackets where significantly higher. Wind is the primary driver of wind chill — a key ingredient in the UTCI calculation.</td></tr>
<tr><td><strong>Dir</strong></td><td>The compass direction the wind is blowing from, shown as an arrow and abbreviated label. Useful for route planning and spray timing.</td></tr>
<tr><td><strong>Cloud</strong></td><td>Total cloud cover as a percentage of sky. High cloud blocks solar radiation, reducing daytime heating and UV exposure.</td></tr>
<tr><td><strong>Sun °</strong></td><td>The angle of the sun above the horizon in degrees. Below 0° the sun has set. The higher the elevation, the more intense the radiation reaching the ground.</td></tr>
<tr><td><strong>Direct W/m²</strong></td><td>Shortwave solar radiation arriving as a direct beam from the sun. The primary driver of skin heating on sunny days.</td></tr>
<tr><td><strong>Diffuse W/m²</strong></td><td>Solar radiation scattered from all directions across the sky. Present even under cloud cover; contributes to the overall solar heat load.</td></tr>
<tr><td><strong>Tmrt °C</strong></td><td>Mean Radiant Temperature — the temperature your skin effectively "sees" from all surrounding surfaces and the sun combined. Can exceed air temperature by 20–30 °C on a sunny day; this is why shade feels so much cooler.</td></tr>
<tr><td><strong>UTCI−Air Δ</strong></td><td>The gap between the UTCI felt temperature and the plain air temperature. A large positive value means solar radiation is adding significant heat stress beyond what the thermometer shows.</td></tr>
<tr><td><strong>UTCI °C</strong></td><td>Universal Thermal Climate Index — the raw felt temperature combining air temp, humidity, wind, and solar radiation. Does not include precipitation effects.</td></tr>
<tr><td><strong>UV-A</strong></td><td>Estimated UV-A radiation index. UV-A penetrates deeper into the skin and contributes to long-term ageing and some skin cancers, even through glass. Present throughout daylight hours.</td></tr>
<tr><td><strong>UV-B</strong></td><td>Estimated UV-B radiation index. Causes sunburn and drives vitamin D production. Intensity falls sharply at low solar elevations due to the longer atmospheric path length.</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. A guide, not a medical measurement.</td></tr>
<tr><td><strong>UTCI+P °C</strong></td><td>SunScope's adjusted felt temperature: UTCI plus the soak-factor penalty for rain and snow. Wet clothing and skin can reduce the effective felt temperature by up to 8 °C in heavy, windy rain.</td></tr>
<tr><td><strong>Precip mm</strong></td><td>Expected rainfall or snowfall in mm per hour. Even light drizzle meaningfully reduces felt temperature when combined with wind.</td></tr>
<tr><td><strong>Soil °C surface</strong></td><td>Temperature of the soil at the surface (0 cm depth). Most seeds germinate above 7–10 °C. Useful for sowing decisions and frost assessment.</td></tr>
<tr><td><strong>Soil °C 6 cm</strong></td><td>Soil temperature at 6 cm depth — the root zone for many crops and seedlings. Lags behind the surface by several hours.</td></tr>
<tr><td><strong>Soil moisture</strong></td><td>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.</td></tr>
<tr><td><strong>Concrete °C</strong></td><td>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.</td></tr>
<tr><td><strong>Vehicle °C</strong></td><td>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.</td></tr>
<tr><td><strong>Indoors °C</strong></td><td>Estimated temperature inside a typical UK brick house with windows closed and no active cooling. Accounts for wall conduction, window solar gain, and thermal mass — indoor peak typically lags the outdoor peak by 2–4 hours.</td></tr>
<tr><td><strong>Managed °C</strong></td><td>Estimated indoor temperature following standard UK heatwave advice: curtains closed during the day to block solar gain, windows opened whenever outdoor air is cooler than inside. Shows the benefit of passive cooling over doing nothing.</td></tr>
