What's in store for the remainder of the weekend? - Settled with high pressure still in charge for the North Island. - Morning fog patches possible. - More rain for the west coast of the South Island on Sunday. - Temperatures on the rise through Sunday with a building northwesterly wind. Latest forecasts: metservice.com

What's the current weather? 🔍🛰️ Lots of clear skies, although areas of low cloud or fog are taking their time to clear. As we head towards the winter solstice, we have less incoming solar energy to our part of the world, so cloud takes longer to lift and clear. It's cloudier for central and southwestern regions. Can you see the deeper cloud bubbling up on the west coast? That's bringing rain to Hokitika at the moment. Latest satellite imagery: metservice.com/maps-radar/sat…

It's a foggy start for some today. Auckland has been seeing (or not seeing 😂) plenty of fog! So has Masterton. ⬇️ This will gradually lift and clear with increasing daytime temperatures. Find our forecasts here: metservice.com

Auckland's air temperature warmed slightly overnight. How does that happen? 📷 The diagram below shows temperatures from two different nights in Auckland this week. 📷 Blue line = Wednesday night (clear skies) 📷 Yellow line = Thursday night (cloudy skies) Notice how, toward midnight, the temperatures follow very different paths. The yellow line (cloudy night) levels off and even rises slightly, while the blue line (clear night) continues to cool until around sunrise. So what's happening? During the day, the ground absorbs energy from the Sun and warms up. At night, that heat is gradually released back into the atmosphere and out towards space. On cloudy nights, clouds act a bit like a blanket, absorbing and re-radiating some of that heat back towards the surface. This slows the cooling process and can even allow temperatures to rise slightly overnight if warmer air is mixed down from above. That's why Auckland was slightly warmer under cloud cover than it was beneath clear skies the night before.

We’ve seen touches of winter for many regions this week, with frosty conditions and noticeably cooler overnight temperatures. Christchurch and Auckland have reached their lowest temperatures for the year, with –2.7°C and 0.3°C respectively recorded at their airports. ❄️☀️🌡️ Even Northland, Auckland, Bay of Plenty, and the Coromandel, areas that are usually too warm to see frost, will see some patches. This is due to a high pressure system that remains the dominant feature through much of the weekend, bringing generally settled conditions to most regions. This should provide a settled end to the Fieldays event and generally favourable conditions for the Warriors’ clash against the Sharks on Saturday evening in Auckland🏉 Up the Wahs!

Another nice day for Whakatāne! It was a frosty start for many, but the sun is here to warm everything up. Maybe warm enough for a certain group of colourful hill-dwellers to come out of a hibernation that's lasted since 2001... ☀️👶 Have a great morning, Aotearoa!

Early afternoon aerial view 🛰️ 🔎 It's a sunny day for many! See all the clear sky in the satellite image below ⬇️ You can even make the snow on the Southern Alps! 🏔️ Still cloudy though for those in the southeast of the North Island and the far south of the South Island.

Swell Forecast (Wednesday to Thursday morning) 🌊 The heavy swell around our coast (above 4 metres) will continue to track to the northeast today and ease around our shorelines as high pressure builds in from the Tasman Sea. Latest marine forecasts: metservice.com/marine

A cold and frosty start for many. Areas with clear overnight skies (without the blanket of cloud) have seen temperatures drop to the low single digits with a few places below freezing! 🥶 If you have seen any frost this morning, please share some photos! Latest forecasts: metservice.com

🟡 Yellow Strong Wind Watches remain in place for coastal parts of Gisborne/Tairawhiti and Hawke's Bay from Tolaga Bay to Mahia Peninsula, coastal parts of Wairarapa and the Tararua District, and the Chatham Islands, easing later today (Tuesday) 🟡

Huge thanks to Greater Wellington Regional Council, Environment Canterbury, and Port Otago for the wave observations reported here, and to the many other wave buoy providers around the motu whose observations support our swell forecasting💙 @greaterwgtn @ECan

🌊Waves are rising rapidly along the east coasts of the North and South Islands, and at the Chatham Islands🌊 ⚠️Steer clear of the beaches today, and keep an eye out for any advice from your local council and emergency management services⚠️

Hazardous swells set to impact eastern New Zealand early this week. A powerful southerly swell is expected to affect eastern coastlines from Otago to Gisborne through to midweek, bringing large waves and dangerous coastal conditions. These long-period swells carry significant energy, allowing waves to surge further up beaches, over coastal roads, and into low-lying coastal areas than usual. Potential impacts include: ⚠️ Dangerous conditions near the coast ⚠️ Coastal inundation and wave overtopping ⚠️ Ferry disruptions and transport delays ⚠️ Local Road closures in vulnerable areas If you're heading to the coast, stay well back from the water's edge and keep up to date with advice from local authorities and the latest Heavy Swell Warnings at metservice.com/warnings.

🌡️An unseasonably warm start today, especially for the east coast of the South Island as pre-frontal northwesterly winds keep temperatures elevated. ❄️ A cold front is forecast to sweep through the south later today, bringing a sharp drop in temperatures behind it. This will see places like Timaru fall from the high teens to the mid-single digits 🥶

🌊 Marine Forecast Heads Up 🌊 Combined wave heights in eastern offshore waters could reach or exceed the height of the Ohakune Carrot🥕 Hazardous conditions mainly for offshore vessels operating in exposed eastern waters. Forecasts will be updated at midday, so keep an eye on the latest information if this may affect you. metservice.com/marine/coastal metservice.com/warnings/marine
