Frost & Fog Watch

Tonight's frost risk and today's fog for the valley, hour by hour, on the published Met Office scales — in plain words, with the Bureau of Meteorology forecast alongside.

About these tools

Yackandandah sits low in a valley where two creeks meet, so on clear, still winter nights cold air drains off the hills and pools over the town — and the floor frosts hard even when the slopes stay clear. It's a modelled estimate for the area, not a measurement; for the official forecast, see the Bureau of Meteorology below.

Today, Monday 24 August

A modelled estimate, not a measurement

Frost and fog change slope to slope and minute to minute — a sheltered terrace can frost while the road stays clear, and a bank of fog can roll in within the hour. This page is a model’s best guess, never a measurement and never a promise. Drive to the conditions you can see, cover tender crops on the cold nights, and for anything that matters use the official forecast.

How this page decides

Frost uses the UK Met Office frost definitions, applied to the forecast minimum air temperature: Ground-frost risk when the low is between 0 and 4 °C (surfaces can still cool below the air on a clear, calm night), Air frost when the air itself reaches 0 °C or below, and we call the coldest nights — around −2 °C and below — Hard frost.

Fog uses the standard WMO and Met Office fog definitions, applied to the modelled visibility: Mist from 1 to 5 km, Fog below 1 km, and Dense fog below 200 m. The number is the model’s visibility for the area, not a reading on your road.

Reading it for what you’re doing

On the roads out of town

Frost and early fog catch the shaded bends, the timber creek bridges and the climbs to Beechworth, Stanley and Wodonga first, and fog can drop visibility to a few hundred metres. When frost or fog is flagged for the morning, slow right down, leave more room, and use low beams — high beams just bounce back off the fog.

For the garden and the orchard blocks

An air frost burns tender vegetables, seedlings and blossom. When one is flagged, cover what you can or bring pots under cover overnight, and hold off planting out until the run of frost nights eases. The coldest hour is usually just before dawn.

Pipes, paths and an early start

A hard frost can freeze exposed pipes and taps overnight and leaves footpaths, decks and the main-street verandah edges slick first thing. Give them time to thaw, or take the sunny side of the street.

Worth knowing

A frost hollow on the valley floor

Yackandandah sits at about 300 m where Yackandandah and Nine Mile creeks meet, and on clear, calm winter nights cold air slides off the surrounding hills and settles in the valley — so the town centre can frost even when the higher ground does not. July is the coldest month, with overnight lows averaging close to 3 °C and dipping below zero on the clearest nights.

Fog forms on the same cold, still nights

The clear, windless nights that bring the hardest frost also let fog settle along the creeks and low ground by morning. It usually burns off as the sun reaches the valley floor. This page reads the forecast fog as well as the cold, so it stays useful outside the frost months too.
