Shiplake to Henley walk

Met Office Forecast

South East England

Sunny or clear spells. Showers likely Sunday afternoon.

Today:

Early cloud and rain soon clearing Kent, then dry with sunny spells before scattered showers develop by the afternoon. Showers might be rather heavy, although coastal areas may remain dry but winds here will become strong again. Maximum Temperature 22C.

Tonight:

One or two showers at first, mainly affecting more western areas, then turning dry during the evening. Some long clear spells for all parts overnight, and turning quite cool. Minimum Temperature 9C.

Monday:

After a chilly start Monday will be bright with sunny spells. Scattered showers developing during the afternoon, perhaps heavy with thunder. Some areas might remain dry. Winds easing later. Maximum Temperature 22C.

Outlook for Tuesday to Thursday:

Sunny or clear spells and scattered showers most days, with a lot of dry weather expected, particularly Thursday. Winds becoming light, and feeling warmer later in the week.

Day 6-7 and Week 2:

Thursday will see further spells of rain and perhaps stronger winds affecting northern parts of the UK, with the south more likely to remain largely dry with sunny spells. The end of the week and into the weekend is uncertain at this stage, but will probably see the unsettled weather continuing, mainly across the north and northwest, with drier and brighter conditions elsewhere. Temperatures will recover to near or above average by day. During the remainder of the month high pressure is likely to remain close by to the southwest bringing periods of settled and warmer conditions, especially across southern areas, with perhaps the chance of some thundery showers moving up from the near continent. The north and northwest may see further spels of wet and windy weather at times.

Week 3 and 4:

Confidence remains rather low during this period. However, there are signs that high pressure will increasingly dominate the weather across the UK. Southern areas are most likely to see the driest and sunniest weather at first, perhaps with some lingering wet and potentially windy conditions affecting the north. However, longer spells of dry and sunny weather may occasionally develop across all parts. Temperatures are generally likely to be warmer than average, although there is little indication of anything exceptional at this time.

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!
