Knebworth to Welwyn Garden City walk

Met Office Forecast

East England

Cloudy with patchy rain in the north. Drier further south.

This Evening and Tonight:

Cloudy across the north of the region, with some patchy rain, easing later in night. Drier in the south but largely cloudy. Light westerly winds. Minimum Temperature 3C.

Tuesday:

Any rain, soon clearing to leave a largely dry, but rather cloudy day, with just a few bright or sunny spells. Rain and brisk winds spreading in late Tuesday night. Maximum Temperature 11C.

Outlook for Wednesday to Friday:

Windy Wednesday with rain, persistent at times. Turning very windy overnight into Thursday with heavy showers. Remaining breezy on Friday with further showers.

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 : East England : 2021-03-08T12:20:55

Daylight : Hertfordshire

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 : Hertfordshire

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!
