When is the best time to walk Te Araroa from Picton to St Arnaud?

On Te Araroa from Picton to St Arnaud, the most reliable start window is late December to early March, or late October to early November. That’s when daylight is long, the Richmond tops are largely free of snow and ice, and you’re more likely to catch a settled spell between fronts.

This stretch runs from the breezy, shower‑prone Marlborough Sounds into the exposed Richmond Ranges, where wind, strong sun, and fast‑rising rivers are the main considerations. Even in summer, plan for changeable weather and keep a rest day up your sleeve.

Best time: January, February, early March

• Why it’s good: Long daylight and generally settled weather make the big Richmond days more manageable. The high routes are usually clear of snow, and rivers are often lower than in spring.
• What to expect: A mix of sunny days and the odd burst of heavy rain, especially around the Sounds. Wind can be sharp on exposed ridgelines.
• Practical notes: Huts and campsites can be busy; start early for cooler climbs. Carry sun protection and enough water for the tops during dry spells. Wasps are common in beech forest later in summer—keep food sealed.

Also good: late October, early November, late December

• Why it works: Spring is turning the corner—daylight is growing, the track is lively, and late December often feels like the start of the summer pattern.
• What to expect: Changeable conditions. You can still see a cold snap, strong wind, or a dusting of late snow on shaded sections of the Richmonds. Rivers rise quickly after fronts.
• Practical notes: Build in a spare day to wait out weather. Take extra layers and a warm sleep system. Check recent track notes with DOC for any lingering snow or slips on the Richmond route.

The rest of the year

Mid–late March to May (autumn)

• Often calm and clear, but days are shorter and nights turn cold. A lovely time for experienced walkers who don’t mind cooler starts.
• Frost, early season snow on higher saddles, and fewer daylight hours make Richmond days tighter. Rivers are cold and can still spike after rain.

June to August (winter)

• Not recommended for most. Short days, frequent rain in the Sounds, and snow/ice on the Richmond tops.
• Expect very cold river crossings and icy travel; you may need winter skills and gear. Weather windows are short.

September to mid‑October (early spring)

• Unsettled and wet, with lingering snow and ice possible on higher sections. Rivers often run high after fronts.
• Feels like a “wait for a window” season—only for flexible, well‑equipped parties.

A quick word on local climate

• Marlborough Sounds: humid, showery spells even in summer; tracks can be greasy after rain.
• Richmond Ranges: exposed ridgelines, strong wind, intense sun on clear days, and rapid weather changes. Heavy rain here makes rivers like the Pelorus rise fast.

Choose dates in the mid‑summer window—or those late‑spring/early‑summer edges—then leave yourself a little wiggle room for a front to pass. That’s the recipe for a good trip on this stretch of Te Araroa.
