Pressure and weather in Deptford
Deptford sits in the broken hill country where the Nicholson River drops out of the Victorian high country toward the Gippsland Lakes, an old gold workings area of steep gullies and dry forest. Weather here arrives on the great procession of cold fronts that ride the Southern Ocean westerlies from the Bight, and each one follows the same rhythm: a hot dry northerly building ahead of the change, a sharp wind shift to the southwest, and a pressure rise behind it as a cool maritime airmass floods in off Bass Strait. Those swings are strongest from August through November, which is also when the deepest lows track closest to the Victorian coast. Summer brings the fire weather pattern, days of intense northerly flow drawn from the interior with the barometer sagging ahead of the front. Autumn is the quietest stretch, when slow-moving highs park over the Tasman and settle the air for a week at a time.
What this means for you
The Victorian cold front is one of the most abrupt pressure signatures anywhere, often turning from falling to rising within an hour of the wind shift. If you use a migraine tracker app, logging the change time rather than the day gives you far more to work with here.
