Blackheath to Canary Wharf walk

Met Office Forecast

South East England

Dry and bright Tuesday. Wet and windy from Wednesday.

Today:

Early rain soon clearing to leave a dry and generally bright day with light winds. Some sunny spells possible with mild temperatures. A little cloudier in the west later, with winds starting to strengthen. Maximum Temperature 13C.

Tonight:

Starting dry, but cloud, rain and strong winds soon spreading east. Rain will be persistent and occasionally heavy at times. Strong winds affecting all areas by dawn. Minimum Temperature 4C.

Wednesday:

Cloudy with persistent rain, heavy at times for much of the day, this becoming patchier later. Strong winds throughout, with a risk of coastal gales. Rain clearing to showers overnight. Maximum Temperature 10C.

Outlook for Thursday to Saturday:

Heavy, blustery showers Thursday with a risk of thunder and strong winds. Windy Friday and Saturday, with heavy showers, but maybe a longer period of rain overnight into Saturday.

Day 6-7 and Week 2:

The weather is likely to remain unsettled and often windy into the start of this period. All areas in the UK are likely to see showers or longer spells of rain at times. Western areas will be wettest with eastern areas seeing more prolonged, drier interludes. Some snow is likely over northern hills, as is expected for the time of year, but overall, temperatures will be around average. Into the following week there is a chance of more settled, drier and brighter conditions in southern areas initially but perhaps extending to the rest of the country for a time. Temperatures are again expected to remain around average initially, but may become milder as things settle down next week.

Week 3 and 4:

Into the latter part of March, unsettled conditions are likely to be increasingly confined to the north and west of the UK, with the south and east probably seeing more settled conditions. Into the beginning of April, there is a chance that the settled conditions will become more widespread to bring some drier spells of weather for most. Temperatures are most likely to remain near to or slightly above average, with any colder or cooler intervals short-lived.

Met Office : South East England : 2021-03-09T02:53:54

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!
