Before Summer Ends: Perfect Weather From Phoenix — Mar del Plata

1. Mar del Plata, Buenos Aires

Rank 1 isn’t a trophy — it’s a forecast fit. Mar del Plata (Buenos Aires) lands near 51°F with only light rain on the books (~0.10 in), which is exactly the band people want for highs under 75°F.

What makes Mar del Plata useful isn’t hype; it’s timing. For 2026-09-12 – 2026-09-13, it reads like a place where you can help plan a short getaway around highs under 75°F and still have a backup café if a cloud shows up.

Bottom line for Mar del Plata: it’s on this list because it supports current recommendations for highs under 75°F, not because it always trends on social. That’s the difference between a real weather guide and a postcard.

2. Tekapo, Canterbury

Tekapo in Canterbury is one of the clearer matches for under-75°F weekends on this weekend’s board — a 53°F high and 37°F low with only light rain on the books (~0.08 in).

This is the kind of mountains stop you discover when you stop browsing generic guides and start asking for weather-perfect weekends. You can actually plan a trip around outdoor time here without pretending the sky will cooperate out of kindness.

If you’re comparing two or three towns, weigh Tekapo’s 53°F high against how you actually want to feel outside — then lock the plan once it feels like weather you’ll love.
