Edinburgh Air Quality (Pollen and UV)

Updated: Sat, 22-Feb at 17:36

Key : Low Medium High Very High

Pollens

These pollens are shown (in season):

• Grass
• Alder and birch (trees)
• Mugwort and Ragweed (weeds)

When out walking, wraparound glasses, a disposable or washable facemask, and being at the front of the group, all help.

Other forecasts: Met Office, University of Worcester

UV and Air Quality

The UV forecast takes account of cloud cover.

"Air Q", the European Air Quality index, is a mix of dust/particulates, ozone, sulphur and nitrous oxides

Edinburgh Visibility

Updated: Mon, 20-Jan at 08:36

Visibility in km. Above 50km is 'good'. Humidity and air pollution make it worse. Theoretical maximum is 300km/200 miles in clean dry polar air.

On the South Downs, at ~ 170m/500ft, the horizon is is ~ 45km/30 miles away. On a mountain at 1,000m/3,000ft, it is ~ 160km/100 miles away. Formula: horizon in km = √ (13 x altitude in m)

Edinburgh daylight

Notes

• Max Height (solar noon) is when the sun is highest in the sky.
• Day length is dawn to dusk as there is enough light for walking for at least 30 minutes before sunrise and after sunset, even on an overcast day.
• At 'Light' (nautical dawn) the horizon becomes visible. At 'Dawn' (civil dawn) there is enough light to read, and drivers can switch their lights off. Finally the sun rises.
• After sunset, there is still enough light to read until 'Dusk' (civil dusk) or lighting up time for drivers. The horizon is still visible until 'Dark' (nautical dusk).
• Times will vary if there is a hill on the horizon.

Edinburgh moonlight

Moonlight chart for walking at night.

Notes

• The percentage of the moon which is illuminated doesn't vary much with location.
• A full moon is not just bigger, it is much brighter. A quarter moon (1/2 disk visible) give less than 5% of the illumination of a full moon. You can walk with a quarter moon if its high in the sky (after dusk for a growing moon, before dawn for a shrinking moon).
• Sky glow (light reflected by air or clouds) from nearby cities, and especially snow on the ground also effect light levels.
• Times will vary a few minutes, as (i) these figures are for the centre of the county the walk is in, (ii) if there are hills on the horizon, and (iii) if you are on a hill
• Sunlight is ~ 1,000,000 times brighter than moonlight.
• Of course, you need a cloudless night as well!
