Weather in Dublin

Here is the outlook for Dublin tomorrow, Saturday 16 August. A calm, settled day under high pressure, starting mild and a touch humid, then warming into a bright afternoon before cloud drifts back in during the evening.

Overnight into the early morning, temperatures hold around 15 degrees with high humidity and partial cloud. Surfaces may be damp from dew, and a light easterly breeze continues. Through the morning the cloud thins, sunshine breaks through, and temperatures lift from 16 to 18 degrees. By early afternoon we reach the day’s peak near 20 to 21 degrees, feeling the same thanks to light winds. Skies are mostly sunny to partly cloudy from late morning to mid afternoon, then a band of cloud moves in after about 19:00, turning the sky overcast for a time without rain. Later at night, some breaks reappear. Winds stay gentle, easterly to east‑southeasterly, generally 4 to 12 kilometres per hour with occasional gusts around 30 to 34 kilometres per hour in the afternoon. Visibility is generally good. No showers are expected and thunderstorm risk is low.

UV climbs to moderate to high, peaking near 7 from roughly 13:00 to 16:00. Sun protection will be important during that window: sunscreen, sunglasses, and a hat. Hydration matters too, especially with the afternoon breeze off the sea.

Clothing-wise, light layers work best. A light jacket or cardigan helps early and late when it feels cooler and a bit damp; short sleeves are comfortable midday.

For young children and older adults, the weather is quite comfortable, but the midday sun is strong, so shade and fluids are wise. Those sensitive to humidity may notice the muggy start; it improves as the day warms.

Drivers can expect glare in the bright late morning and early afternoon sun, then flatter light under evening overcast; a quick windscreen clean helps. Motorcyclists and bicyclists should watch for slick patches from overnight dew early on, and be mindful of a light crosswind from the east on exposed routes. Pet owners will find good walking conditions; keep water handy and prefer longer walks early or later. Garden enthusiasts get a dry window for outdoor tasks; watering is most effective in the evening once the breeze eases and cloud returns.

In summary: dry, pleasantly warm, gentle easterly breeze, sunny spells through the middle of the day with UV near 7, then turning cloudier after 19:00. A good day to be out, with a bit of sun sense and light layers.
