South East England

Light rain and drizzle for many. Isolated heavy showers later.

  • Cloudy and breezy start, with light rain and drizzle moving into many southern and western areas, and turning persistent in places
  • Outbreaks of rain and drizzle then clearing north through the afternoon, but with isolated heavy showers, perhaps thundery, following
  • Maximum Temperature 17C

Tonight:

  • Heavy showers at first, perhaps thundery, clearing northeast by midnight
  • Clear spells follow, perhaps some mist patches developing
  • Further heavy showers then spreading north though early hours of Monday
  • Minimum Temperature 10C

Monday:

  • Early cloud breaking to sunny spells
  • Scattered showers continuing for much of the day, heavy and perhaps thundery at times
  • Eastern parts with the best chance of staying dry
  • Breezy
  • Maximum Temperature 19C

Outlook for Tuesday to Thursday:

  • Sunny spells and showers
  • These occasionally heavy with thunder, and perhaps merging at times
  • Chance for some heavy rain and perhaps stronger winds Wednesday
  • Breezy Thursday, and turning cold later

UK Day 6-7 and week 2

  • A colder interlude across all areas of the UK as northerly winds push south bringing showers, these wintry across hills in the N
  • Perhaps a more organised spell of rain and stronger winds across Scotland especially as we head into the weekend, meanwhile southern areas are likely to see much drier conditions than of late with some sunshine by day
  • Temperatures below average, especially in the north with some overnight frost possible along with some patchy mist and fog
  • Later in the weekend likely to turn more unsettled once more with outbreaks of rain and some stronger winds expected to return to the northwest of the UK especially, although the southeast may well hang on to drier conditions throughout

UK Week 3 and 4

  • A continuation of low pressure systems tracking in from the Atlantic is the most likely scenario for the rest of October
  • This means wet and windy weather at times, especially across England and Wales, but with a suggestion that Scotland and Northern Ireland may be more likely to see longer breaks in the weather, and more in the way of drier spells
  • It is possible that these drier conditions could be seen more widely later in the month as higher pressure further north extends southwards for a time
  • This would also bring an increased chance of overnight fog and frost
  • Temperatures will tend to be close to average overall in the south, but probably below average in the north and northwest

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)

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
  • Of course, you need a cloudless night as well!

Surrey weather (Accuweather)

Now would be a good time for a cup of tea.
