Margaret River hava durumu: Mart

March is the end of the Western Australian summer, still hot and dry, and regulars are honest that the vineyards are past their best - the picking is generally done and the vines are beginning to lose their leaves, so this is not the month for the lush green photographs. Exactly when the grapes come off is something they disagree on, from January to mid-February onwards. What they agree on is the weather: late March into early April is one of the two windows they name, with rarely more than a brief shower and temperatures mild enough for driving the region or walking the beaches all day. Our row backs it at 24.6C over 13.1C with 38.1mm across 4.3 precipitation days. The summer school holidays are over. The record: 10 hours of sun, a 21.5C sea and AQI 20, the cleanest air here.

Regulars are specific this falls within one of the two best windows of the year here, late March into early April, rarely bringing more than a brief shower and mild enough for comfortable beach walking. Our row backs that mild, genuinely dry read, 21.8C over 10.7C nights feeling 9C, with rain light at 56.7mm across 8.2 days and humidity at 69 percent. Regulars are consistent the day-to-night swing runs genuinely wide, sunny 20-plus-degree afternoons giving way to nights that can drop below 10C, a light jacket or fleece worth having for most of the day regardless of how warm it starts. The sea sits at 20.7C. The record: 8.9 hours of sun, a 17.8 kph wind and AQI 23.

November is the window regulars point wine-tourers toward: warm enough for the vineyards without the summer school-holiday crowds that arrive from December. Our row backs a genuinely pleasant spring, 21.9C over 10.3C, with only 32mm across 5.1 days and one of the cleanest air columns in this project at AQI 23. The wind is real at 19.5 kph, and they note it runs stronger still down at Augusta on the Southern Ocean edge of the region than in the wine country proper - worth choosing where you stay for that reason alone. Early November also catches the tail of spring wildflowers. The sea sits at 19.4C, a look-more-than-swim proposition on this coast even in late spring. The record: humidity 66 percent, 11.7 hours of sun.

December here is warm, sunny and unlikely to be wet - our row gives 24.2C with 15.5mm across 2.8 precipitation days - but regulars call Christmas itself a lottery, with one year cold enough to send people shopping for jumpers and another over 43C for days on end. Our monthly average sits a long way under that upper figure. The reliable part is the calendar: Australian school holidays begin mid-December and run to the end of January, families rebook the same week year after year, and the stretch between Christmas and New Year is both the busiest and the dearest. If the dates are flexible, they say keep to early December. The sea is 20.2C, cool as ever here. The record: 11.9C nights, humidity 63 percent, 12.6 hours of sun and AQI 22.

Regulars name early December to late February as the favourite window for this corner of Western Australia, and February has a specific draw: harvest begins from about the middle of the month with the vines still lush and green. Any month works for the cellar doors - free tastings, restaurants, gardens - though they warn that some wineries have no air conditioning and get uncomfortable inside on a hot day. Our row is gentler than an Australian summer sounds: 25.5C by day falling to 13.5C at night, a twelve-degree swing the Southern Ocean is doing, with 21.9mm across 2.6 precipitation days. For beaches they point to Eagle Bay, Prevelly and Gnarabup. The record: humidity 65 percent, 11.5 hours of sun, a 21.1C sea and AQI 21, among the cleanest air here.
