Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cloud
cloud_cover_forecast
Hourly cloud cover for the next 1-48 hours at any point, split into total, low, medium and high cloud plus fog, with the clearest hour picked out. For stargazing, astrophotography, aurora or sunset photography, and estimating solar panel output. Source: MET Norway Locationforecast 2.0 (percent of sky covered, model forecast). Fog is only given for the first few days. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
index
uv_index_forecast
Hourly clear-sky UV index for one day at any point, with the day's peak UV, the time of the peak and the WHO exposure band (low, moderate, high, very high, extreme) with plain protection advice. For sun-safety, outdoor work and holiday planning. Source: MET Norway Locationforecast 2.0. Values assume a cloudless sky, so real UV is lower under cloud (cloud cover is included); UV is only given for the first few days of the forecast. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
marine
marine_forecast
Sea-state forecast for a sea point in northern European waters (Norwegian Sea, North Sea, Skagerrak, Barents Sea and nearby north-east Atlantic, including UK coastal waters): hourly significant wave height and direction, surface current speed and direction, and sea temperature. For sailing, kayaking, fishing trips and coastal swims. Source: MET Norway Oceanforecast 2.0 (nearest model sea point). Not a navigational or safety product; points on land or outside the model area return no rows. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
moon
moon_phase
Moon phase for any place and date: phase name (new, crescent, quarter, gibbous, full), whether it is waxing, approximate illuminated fraction, days from the nearest full moon, the dates of the next full moon and next new moon, moonrise and moonset with bearings, and the moon's highest point. Answers "is it a full moon tonight" and "when is the next full moon" for stargazers, anglers, photographers and night walks. Source: MET Norway Sunrise 3.0 for rise, set and phase angle; full and new moon times are our own calculation (Meeus lunar-phase formulas, accurate to a few minutes) and illumination is approximate. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
rain
rain_forecast_next_hours
Answers "will it rain?" for the next 1-12 hours at any point: whether rain (or snow, as liquid water) is forecast, the first wet hour, the total, and the amount hour by hour. Useful before a walk, run, school run or outdoor job. Source: MET Norway Locationforecast 2.0 hourly precipitation (model forecast, not radar nowcast), times in UTC. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
sea
sea_temperature
Sea surface temperature forecast at a coastal or offshore point in northern European waters (including UK coasts): the temperature now, the range over the next 24 hours, and hourly values. For open-water swimmers, surfers, divers and anglers. Source: MET Norway Oceanforecast 2.0 (model sea temperature at the nearest model sea point). Not a measured buoy reading; points on land or outside the model area return no rows. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
sunrise
sunrise_sunset
Sunrise, sunset, solar noon and day length for any place on Earth and any date, with the sun's compass bearing at rise and set, its height at noon, and civil twilight (first light and last light) and golden-hour times. Handles polar day and polar night. For photographers, walkers, anglers, prayer and event timing. Source: MET Norway Sunrise 3.0 for sunrise, sunset and noon; twilight and golden hour are our own calculation (standard NOAA solar-position formulas) and labelled as derived. Times are in the UTC offset you give, default +00:00: pass +01:00 for UK summer time (BST), as daylight saving is not applied for you. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
wind
wind_forecast
Hourly wind forecast for the next 1-48 hours at any point: mean wind speed in mph, km/h, knots and m/s, the compass direction it blows from, and the Beaufort force with its name (for example "fresh breeze"). For cycling, sailing, drone flying, kite flying or securing garden furniture. Source: MET Norway Locationforecast 2.0. Speeds are 10-minute mean winds at 10 m; gusts are included only where MET Norway provides them. Needs lat and lon: for a UK place name or postcode, get coordinates from geocode or postcode_lookup first. (cost: 1 credit)
