Wales

Mainly dry and hot today, thunderstorms for some tomorrow.

  • Somewhat cloudier than yesterday with isolated showers this morning
  • Otherwise mainly dry with sunny periods, these developing more widely by this afternoon
  • Feeling hot in the sunshine though breezier than yesterday
  • Very high pollen levels
  • Maximum Temperature 28C

Tonight:

  • Very warm and largely sunny this evening
  • Uncomfortably warm and humid overnight with showers and some lightning possible later
  • Low cloud and sea fog arriving in many western coastal regions
  • Minimum Temperature 18C

Saturday:

  • Very warm and humid with bright or sunny spells
  • Scattered showers breaking out, with thunderstorms possible
  • Localised torrential downpours and large hail in north Wales later
  • Many places staying dry
  • Maximum Temperature 26C

Outlook for Sunday to Tuesday:

  • A fresher and breezier spell of weather from Sunday and into next week
  • Whilst showers are possible at times, prolonged dry periods are likely with warm sunny spells at times

UK Day 6-7 and week 2

  • Rather changeable conditions are anticipated through this period, as a series of Atlantic low pressure systems pass largely to the northwest of the UK
  • These will tend to bring some occasional rain or showers, most frequent in northwestern areas where it may also be rather breezy or windy at times
  • Whilst some rain or showers will be possible farther south and east, here longer drier spells are more likely, under the influence of higher pressure
  • There is also the chance of some occasional very warm weather, as south or southwesterly winds allow brief bursts of hotter air to encroach from the continent, but probably fairly short-lived and perhaps also accompanied by a few thunderstorms at times

UK Week 3 and 4

  • Rather changeable conditions are anticipated through the first half of July, the wettest and windiest conditions most likely towards the northwest with a risk of some heavy rain at times, especially over hills
  • Southern and eastern areas are most favoured for longer drier and more settled spells, although even here some occasional rain or showers will be possible, perhaps thundery
  • Temperatures are expected to be above average for most areas, especially towards the southeast where there will be an ongoing chance of some very warm or hot conditions at times

Today
Fri, 20-Jun

Largely dry, with sunny spells. Very warm and feeling rather humid.

Fine and dry, with good spells of sunshine. However, there will be some medium to high-level cloud developing into the afternoon, which gives the very low chance of an isolated heavy shower. However, the majority of routes should remain dry.

Low risk Thunderstorms
High risk Strong Sunlight
Chance of Cloud free tops 95%.
Ground conditions Please see - https://yrwyddfa.live/
Visibility Cloud remaining above summit level, although some shallow mist or valley fog cannot be completely ruled out first thing. Generally good or very good visibility, possibly falling to moderate in any isolated showers.
Confidence High confidence for very warm temperatures and mostly dry conditions on Friday, but lower confidence in regards to the risk of thunderstorms developing late Saturday. Also High confidence for fresher conditions to move in Sunday, with more changeable conditions following through the coming week. However details are low confidence at this stage.
View A very warm, humid and sunny day, so plenty of drinking water and appropriate sun protection will be required. Possibly a waterproof layer required if an isolated heavy shower developed.

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

  • 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.

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!

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