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.
Town Tools builds free, public tools for Yackandandah and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.
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. This page reads the forecast for tonight's frost risk and today's fog, hour by hour, in plain words. It's a modelled estimate for the area, not a measurement; for the official forecast, see the Bureau of Meteorology below.
No frost expected today. Dense fog likely 8 pm–10 pm.

A modelled estimate, not a measurement
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.
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.
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.
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.
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.

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.
