Where to go

1. Half Moon Bay, California

Half Moon Bay in California is one of the clearer matches for golf weather on this weekend’s board — a 65°F high and 54°F low with only light rain on the books (~0.15 in).

This is the kind of beach 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 Half Moon Bay’s 65°F high against how you actually want to feel outside — then lock the plan once it feels like weather you’ll love.

Things to do

2. Mammoth Lakes, California

If you’re scanning for current recommendations, put Mammoth Lakes near the top of the list: weekend air around 68°F / 52°F, plus a dry outlook with little to no rain.

What makes Mammoth Lakes useful isn’t hype; it’s timing. For 2026-08-22 – 2026-08-23, it reads like a place where you can help plan a short getaway around dry, mild course days and still have a backup café if a cloud shows up.

Bottom line for Mammoth Lakes: it’s on this list because it supports current recommendations for dry, mild course days, not because it always trends on social. That’s the difference between a real weather guide and a postcard.

Things to do

3. Monterey, California

If you’re scanning for current recommendations, put Monterey near the top of the list: weekend air around 65°F / 56°F, plus a dry outlook with little to no rain.

Call it a hidden gem or a familiar favorite — either way, the point is the outlook. Travelers trying to find your perfect weather for 2026-08-22 – 2026-08-23 should shortlist Monterey before the hotter or wetter options crowd the tab.

Use it as a concrete recommendation: fly or drive for golf weather, keep an eye on updates, and treat 65°F as your planning anchor — not a vague “nice weather somewhere.”
