October in Boise, ID: peak season for golf — great conditions and a wide playing window. Best tee times: mid-morning through early afternoon.
| Average October Weather | |
|---|---|
| Avg daily high | 67°F |
| Avg daily low | 44°F |
| Rainy days | 6 / mo |
| Avg peak wind | 11.2 mph |
Temperature is the one variable that defines golf in Boise in October. The average high of 67F sits right inside the ideal playing window, but the 23-degree daily swing from that 67F high down to a 44F low means the same course can feel like two different rounds depending on your tee time. Morning starters will want layers; afternoon players can often peel down to a single mid-layer by the back nine.
Otherwise, the conditions are quietly favorable. Six precipitation days make October the third-driest month of the year, and the 11.2 mph peak wind is the third-calmest reading on the calendar. The season-tier badge says Peak, and the numbers back it up — you're mostly dealing with cool air, not rain or gusts.
Book afternoon tee times in the 1–3 PM range to take advantage of the daily high near 67F and let on colder mornings near the low end of the range clear before your round. Rounds starting before 8 AM can see temperatures in the mid-to-upper 40s, which is manageable but dress accordingly. See how conditions rate hour by hour on our playability scale.
September is 16 degrees warmer at an 83F average high and logs only 3 precip days, so moving into October the weather gets cooler and wetter — though still very playable. November drops another 19 degrees to a 48F high and adds 5 more rain days, which is where the playable window effectively closes for most golfers. October sits in the gap between those two months — still dry enough and warm enough to be worth the trip, but clearly trending toward winter.

Yes — October earns a Peak season rating largely because of its precipitation and wind profile. Six rain days make it the third-driest month of the year, and 11.2 mph peak wind is tied for third-calmest. The main trade-off is the cooler 67F average high compared to summer months, so afternoon tee times get the most out of the available warmth.
The average low drops to 44F, which is typically where overnight and early-morning temperatures settle. By mid-afternoon, highs reach 67F on average, putting the temperature squarely in the comfortable range. The 23-degree daily swing is the practical challenge — dress in removable layers rather than a single heavy jacket.
