Wales

Cloud and patchy rain clearing to sunshine spells and showers.

Today:

It will be a cloudy start with patchy rain, low cloud and hill fog in places. However, the cloud will clear into the afternoon with some sunny spells developing, along with a scattering of showers. Feeling pleasant in the sunshine. Maximum Temperature 20C.

Tonight:

Any showers will ease through the evening to leave a mainly dry night for all. There will be clear spells for most, but the cloud will gradually increase towards dawn. Minimum Temperature 10C.

Monday:

A rather cloudy start, but sunny spells will soon develop through the morning. Scattered showers are likely into the afternoon, some of which could be heavy. Feeling fresher for all. Maximum Temperature 15C.

Tuesday to Thursday:

Further sunshine and showers on Tuesday. Windier on Wednesday with rain followed by showers. Staying mostly dry on Thursday. Feeling fresher throughout.

UK: day 6-7 and week 2:

Dry conditions with sunny spells are expected for most on Friday, although some cloud and light rain or showers are likely to be seen in the northern regions. Over the weekend, fine and dry weather will persist, however some light showers remain possible, especially in the north and east. Near normal temperatures can be expected for most, perhaps feeling warmer in the south and southwest. Into the following week, the weather is likely to become more settled, with any few showers most likely to be seen in the north and east. This means drier conditions and above average temperatures for most, particularly in the south and southeast, and fewer showers all round. As we move into the beginning of June, drier than average conditions are expected to persist overall.

UK: week 3 and 4:

In the beginning of June, we can expect to see a lot of dry weather across the UK. Temperatures may potentially become warm in the south and southwest but remaining closer to average in the north. Later on in June, we may however see some less settled and cooler weather, particularly in northern regions.

Daylight : Snowdonia

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 : Snowdonia

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!
