Updated 5:40pm – Wednesday evening 28/03/2018.


The questions are flooding in, how’s Easter looking? Well it’s looking superb for Canterbury under high pressure. We have one slight blemish, a cooler weak southerly front that will work north on Saturday afternoon, but it doesn’t have a lot of sting and will lose its momentum on arrival here in Canterbury; perhaps a few isolated showers and a cooler ‘pool’ of air for a 6-8-hour period. Rainfall – isolated in nature, with 1-5mm for most of Canterbury.

Overall, it’s looking superb across the region, with mostly sunny skies, settled conditions and yes, it will be around 3-4 degrees above average for the time of year. Perfect for heading into the High Country and getting out and making the most of the long weekend. In terms of winds, we’re looking at gusty NW conditions on Saturday afternoon & evening for the High Country and just those frequent easterlies about Coastal Canterbury, we don’t expect any real ‘Punch’ with winds expected to remain below 30km/hr.

FRIDAY: Sunny skies with settled conditions across the region. Areas of morning low cloud and fog possible. Light NE winds, freshening a tad about Coastal Canterbury, remaining light inland.

Map: A computer generated map for Saturday. In terms of a key talking points, this will be as bad as it gets during the weekend; a brief southerly change on Saturday afternoon. Notice the green ( moisture ) out to the east of the South Island, that’s our weak southerly change and the large high pressure in the Tasman set to move in and dominate our Sunday & Monday.  Traditional Canterbury weather patterns and overall pretty settled across New Zealand.
