We can understand why - most of the South Coast has received close to 50 millimeters of rain and as a strong cold front sweeps across the state temperatures have struggled to reach double figures with the Bureau of Meteorology issuing a severe weather warning for large parts of the region.

Certainly a big change from the weekend where large parts of the coast experienced temperatures in the mid to high 20s.

Kiama received 28.6mm of rain to 9am Tuesday and has since received 4mm.

The wind speed has been regularly between 50-60km/hour, with gusts up into the 70s and 80s.

Nowra received 50mm of rain until 9am and has since recorded a further 5.6mm.

Nowra's temperature dropped to single figures at 1.50am Tuesday, hitting a low of 7.7 degrees at 6am.

The temperature failed to reach double figures until just after midday, with the temperature actually feeling much less, hardly above 5 degrees.

Winds have been constant at around 30km/h with a number of gusts over 40km/h.

Out on the coast, at Port Perpendicular 53mm was recorded until 9am with a further 5.2 since recorded.

The wind has been a lost stronger out there, regularly between 30-40km/h with a number of gusts over 50km/h

Milton-Ulladulla recorded 41mm to 9am Tuesday and a further 3.6mm.

The area's temperature didn't reach double figures until around 11.20am and again feels like less than 5 degrees.

Wind speed was registering around 30km/h with a gust height of 52km/h.

In Batemans Bay, 32mm of rain was recorded to 9am and a further 2.4mm since.

The Bay's temperature reached double figures at 10.10am but again was registered as feeling around or less than 5 degrees.

The wind speed was regular between 20-30km/h with gusts of between 40 and 5okm/h.

Bega recorded 30.4mm of rain to 9am and a further 1.3mm.

Winds have ranged from 20-30km/hour with some gusts up over 50km/h.

The temperature hit double figures around 8am and has hovered in the 11 degree mark for most of the day, while the feels like temperature is from 4 to 7.6 degree mark.

The Bureau says a strong cold front sweeping across the state is forecast to move offshore today.

A transient low pressure system will then form within the front, deepening off central coastal waters late today and generating vigorous winds and sea over central and southern waters.

The low is expected to move slowly east during the mid week, with conditions easing as it tracks into the Tasman Sea.

Damaging winds and damaging surf is forecast for the South Coast, winds to average 60 to 70 km/h with peak gusts in excess of 90 km/h are possible along the coastal fringe and northern parts of the South Coast districts from the late afternoon onwards.

Winds are expected to gradually ease below gale or damaging wind thresholds during Wednesday morning as the low slowly tracks to the Tasman Sea.

Damaging surf with significant wave height in excess of five to six metres is expected which may lead to localised damage and coastal erosion, and is likely to continue through Wednesday.

Surf zones exposed to the south and southeast are at highest risk.

Beach conditions in these areas could be dangerous and people are advised to stay well away from the surf and surf exposed areas.

Locations which may be affected include Kiama, Huskisson and Ulladulla.
