Rainham to Grays walk

Met Office Forecast

South East England

Fog patches likely tonight. A few showers on Tuesday.

This Evening and Tonight:

Dry with light winds and prolonged clear spells in the west, becoming cold by dawn with a patchy frost. A mixture of fog and low cloud will form in Kent through the early hours, moving slowly westwards. Minimum Temperature -2C.

Tuesday:

A dry morning with plenty of sunshine, any low cloud receding to the coast. Cloudier with a few showers during the afternoon though feeling warm in any spell of sunshine. Maximum Temperature 18C.

Outlook for Wednesday to Friday:

Cloudy with isolated showers Wednesday, clearing south later. Dry and largely sunny thereafter. Feeling warm by daytime though slightly colder along coasts, due to onshore winds. Some overnight frosts.

Day 6-7 and Week 2:

Generally fine and dry on Saturday, with sunny spells and patchy fair-weather clouds, possibly bringing some showers across the northeast, as well as some rain across the southwest. Gusty winds and possible coastal gales remain likely in the southwest, preventing frosts here; lighter winds elsewhere maintains the frost risk for much of the UK. High pressure is expected to dominate, meaning most places will remain dry and bright, with some morning fog patches in places where winds are light. Temperatures are gradually returning to average, warming slightly by day, although overnight frosts remain probable in rural areas and in the north. The greatest potential for rain and stronger winds is likely across the south and southwest, although confidence decreases into the beginning of May.

Week 3 and 4:

Mixed weather patterns, typical of spring are most likely through the first half of May. Overall, fine and dry weather is expected to be most dominant, with fair-weather cloud and plenty of sunny spells. However, all areas are likely to see some showers or perhaps some longer spells of rain at times, with these unsettled periods more likely than they were in April. Temperatures are likely to be close to the average for the time of year, with the possibility of some warmer spells.

Met Office : South East England : 2021-04-19T14:32:35

Daylight : London

Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.

It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).

Moonlight : London

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, (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!
