Met Office Forecast

South East England

Dry overnight and through Sunday, with warm afternoon sunshine developing.

This Evening and Tonight:

Any remaining showers soon dying out this evening to leave most places dry with spells of sunshine. Remaining dry with light winds and largely clear skies overnight. Minimum Temperature 11C.

Sunday:

Dry on Sunday with plenty of sunshine during the morning. However, patchy cloud will develop by the afternoon, dissipating again in the evening. Feeling warm by afternoon with light winds. Maximum Temperature 26C.

Outlook for Monday to Wednesday:

Dry Monday and Tuesday with plenty of sunshine and becoming very warm or hot. Remaining hot on Wednesday but perhaps cloudier with a risk of thunderstorms.

Day 6-7 and Week 2:

A cold front is likely to make some progress eastwards across the UK on Thursday, with the potential for heavy showers and thunderstorms. Some hot or very hot conditions may persist in the east ahead of this, especially in the southeast. Into the weekend, confidence falls low, but following the cold front, fresher conditions will be the most likely. A northwest to southeast split will be the most likely scenario. The northwest is likely to see further spells of rain and strong winds at times, with temperatures near or a little below average. The south and southeast are likely to see localised heavy rain, with thunderstorms possible, but it will stay warm or very warm into the start of August.

Week 3 and 4:

As we move into early August, the final month of the meteorological summer, confidence is low in the forecast with no one single weather pattern looking to dominate. It is most likely that low pressure to the north and northwest of the UK will give further rise to showers or longer spells of rain in the northwest, with the better chance of drier weather in the southeast. Temperatures will likely be above average, perhaps mostly in western and southern areas. However, confidence falls as we head through August.

Notes

  • The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
  • A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half 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, and, (ii) if there are hills on the horizon.
  • Of course, you need a cloudless night as well!
