Weather Outlook, Illawarra and Southern Highlands - Sunday 17th August 2025.

Slight chance of a shower this evening in the south of region such as Ulladulla and Jervis Bay. May even be a flash to be seen over ocean. Tomorrow a mix of sun and cloud with west winds morning, more SW in afternoon. Chance of a shower late in day or evening, mainly places like Jervis Bay again. Possible thunderstorm out to sea. 16-17C, but will feel warmer out of wind. HIGHLANDS: Very slim chance of a light shower next couple of hours. Although it will be borderline cold enough tonight, lack of moisture should keep and sleet / snow away. Tomorrow mix of sun and cloud, but dry. Lighter W/SW winds, but cold at just 10-11C.

Weather Outlook, Illawarra and Southern Highlands - Saturday 16th August 2025.

A mix of sun and cloud tomorrow. There may be a quick moving shower at any stage, but my feeling is zero or 10 drops. Sadly cooler at around 18C. Winds from west, behaving in morning, but may get a bit strong in afternoon and evening. HIGHLANDS: Mix of sun and cloud . Chance of a shower, mainly in the west during middle of day. West winds slowly increasing during the day to strong. Sadly much cooler at 11-12C.

Weather Outlook, Illawarra and Southern Highlands - Friday 15th August 2025.

Further on and off showers this evening and maybe persisting in north of the area overnight. Improving tomorrow, any early showers should clear to a partly sunny day with light winds early, turning NW in afternoon. Warmer in those NW winds at 20C. Weekend possible strong west winds. HIGHLANDS: Possible shower or two this evening in very east. Partly sunny day tomorrow with NW/W winds. Wind may be borderline strong in very south and west. Warmer at around 15C.

Weather Outlook, Illawarra and Southern Highlands - Thursday 14th August 2025.

A 50/50 chance of a shower next few hours., and a smaller chance after midnight or very early AM. Tomorrow some deceptive very early sun but becoming cloudier as day progresses. Another 50/50 chance of a shower after around midday to evening, mainly exposed areas like Jervis Bay and northern suburbs of Wollongong. SW/S winds, possible strong on the very coastal fringe (within 2-3kms of coast) in morning. 16-17C. Warmer Friday, but make the most of it. Good news, if you can call it that ! is models have backed away from the Tasman Sea Low and deluge. However in its place some strong westerlies on weekend, followed by a few days of SW/S winds and miserable spotty showers. HIGHLANDS: A 50/50 chance of a shower next few hours, and a smaller chance after midnight or very early AM. Mainly dry tomorrow apart from an eastern escarpment shower or two. becoming cloudy apart from the very far west where sun patches may persist. 11-12C.

Weather Outlook, Illawarra and Southern Highlands - Wednesday 13th August 2025.

Part sun / cloud morning with west winds. Slightly warmer at 17-18C, but.......a southerly change in afternoon will slowly drop temperatures........and bring some showers in the evening or night. HIGHLANDS: Chance of frost. Becoming cloudier during day. Chance of an afternoon shower from around midday in west. Slight chance of a evening shower in east. West winds morning, southerly in afternoon. Around 13C.

Weather Outlook, Illawarra and Southern Highlands - Tuesday 12th August 2025.

Thankfully those showers today became quite isolated. The radar looked ominous at times but steering shear was low and showers slow moving. Very slight chance of a shower this evening. Tomorrow mostly dry mix of sun and cloud, cannot rule out a rogue shower, but you will be unlucky. Light southerly winds morning, very light and variable in afternoon. Those that trawl weather posts may see another 'build an ark' East Coast rain event around the 18-19th August, at this stage ISC is calling it 'throw a dice status'. One thing is certain, no signs of a break to our winter temperatures except for Friday. HIGHLANDS: Maybe a shower around eastern parts next 2-3hours. Tomorrow a slight chance of frost in far west. A mix of sun and cloud and dry. Light winds and 13C dependent on sun vs cloud ratio.

Weather Outlook, Illawarra and Southern Highlands - Monday 11th August 2025.

One more day of misery guts weather to go. Further showers this evening. may ease off after midnight to the morning hours and like today deceive us into thinking it may be a dry day. But let's be positive it will be 'drier', just not dry. On and off mostly light showers from mid to late morning, dry periods in between and another glimpse or two of that odd yellow sky ball. Light southerly winds. As a cynic will likely say ' a bit of everything' or 'covering all bases', well not quite,- no heat wave at just 15-16C. HIGHLANDS: Mostly cloudy, on and off showers in east, mainly dry west of Moss Vale. Light winds and 11C.

Weather Outlook, Illawarra and Southern Highlands - Sunday 10th August 2025.

By now anyone could almost write the coastal Illawarra forecast. Just mention the word 'showers' and you are most of the way there. Further showers this evening. There may be a slight easing after midnight as winds may shift to a more SW land breeze, but do not fret showers will be back by mid morning tomorrow and persist on and off rest of day With luck a bit less rain accumulation than Kiama / Shellharbour got today. There may even be a some brief cheeky sun peering through the curtains very now and than. SW/S winds early, SE from around mid morning. Still rather cool sadly at around 15C. HIGHLANDS: Showers in eastern parts this evening. Similar tomorrow, mostly cloudy with showers in the east, mainly dry west of Moss Vale, Light SE winds and 11-12C.

08/08/2025

Weather Outlook, Illawarra and Southern Highlands - Saturday 9th August 2025.

Showers likely to develop over next few hours and persisting through tomorrow on and off. SW/S winds early, turning more SE later. A rather cool 15-16C. HIGHLANDS: Mostly dry this evening, accept for eastern escarpment later this evening. Showers slowly spreading from the east to west during day tomorrow. Light SE winds and a miserable 11-12C.

07/08/2025

You greedy sun hogs have had your two lovely days, but from tomorrow its back to winter. The good news if you can call it that is while the next seven days may have nuisance showers and be under average temperature wise, at least there is no Tasman Sea low pressure systems, and no upper cold pools so rainfall is expected to be much less. A southerly is moving up the coast, there are light showers on far south coast as I write ( 6.00pm), a couple may reach Illawarra before midnight, but more likely later. Not much in it just a couple of mm, and possible none away from coastal strip (like Albion Park). Any showers will contract north quickly in early morning. Mix of cloud and 'some' sun rest of day. Southerly winds moderate to fresh right on coast side in morning, slowly easing during afternoon. A cool 16C. The HIGH that will be responsible for this southerly is likely to centre over Tasmania on the weekend leading SE winds and increased showers. HIGHLANDS: The far east may get a quick passing shower early morning. A cool day, mostly cloudy morning, sunny periods in afternoon. Light winds and just 11-12C.

05/08/2025

Weather Outlook, Illawarra and Southern Highlands - Wednesday 6th August 2025.

Another sunny day on the way. Just a tad cooler due to cooler winds. West winds in morning and maybe moderate. Winds turning lighter SW in afternoon and southerly very late in evening. That southerly change may bring a shower around Jervis Bay / Ulladulla before midnight, spreading throughout briefly on Thursday morning. Around 19C. HIGHLANDS: Chance of frost in the west of region. Sunny day with moderate west winds. 13-14C.
