How to use this: Days with higher scores are generally better for hiking and outdoor activities, with more comfortable temperatures, lighter winds, and fewer weather impacts.
July offers the most consistently comfortable weather at Olympic National Park’s Hurricane Ridge, while August and September provide excellent hiking conditions with fewer crowds.
Based on 2025 Perfect Weather Index (PWI) data from the Hurricane Ridge Visitor Center (high elevation), Olympic shows a dramatic seasonal contrast: a long, wet, cloudy cool season and a short but exceptional summer window. Conditions at Hurricane Ridge differ substantially from the park’s rainforests and coastal zones, where temperatures are milder and precipitation patterns vary.
Raw monthly totals were normalized into monthly PWI scores (percent of possible points) and paired with the number of rare Perfect 10 days.
| Month | Monthly PWI Score | Perfect 10 Days | What It Means | |
|---|---|---|---|---|
| January | ~55% | 0 | Cold, snowy, limited access | |
| February | ~46% | 0 | Wet, cloudy, lowest comfort | |
| March | ~44% | 0 | Winter lingers | |
| April | ~63% | 0 | Improving but variable | |
| May | ~64% | 0 | Cool, gradually stabilizing | |
| June | ~76% | 2 | Strong early summer window | |
| July | ~86% | 7 | Peak reliability and comfort | |
| August | ~81% | 3 | Warm, dry, very stable | |
| September | ~80% | 3 | Crisp, excellent visibility | |
| October | ~60% | 0 | Rapid shift to wetter pattern | |
| November | ~51% | 0 | Storm season returns | |
| December | ~46% | 0 |

July clearly ranks highest, with the strongest overall score and the most Perfect 10 days. August and September follow closely, maintaining high comfort with slightly fewer visitors compared to peak midsummer weekends.
Olympic National Park contains three distinct climate zones:
While summer dominates at Hurricane Ridge, rainforest valleys may remain comfortably cool even in shoulder seasons. Conversely, storm systems impact ridge elevations more quickly and intensely.
Winter conditions dominate at Hurricane Ridge. Snowpack, road closures, and limited services keep comfort scores low.
Best for: Snowshoeing, winter photography
Watch for: Access restrictions, storm systems
Spring is highly variable. Snow lingers into late May at elevation, though lower areas begin improving sooner.
Best for: Waterfalls in lower elevations
Watch for: Mud, changing access
Summer delivers Olympic’s best weather of the year at elevation. Dry Pacific high pressure reduces precipitation, skies clear, and temperatures become ideal for alpine hiking.
Best for: Hurricane Ridge trails, wildflowers, long hikes
Watch for: Peak-season visitation in July
Early fall remains excellent, especially September. By October, Pacific storm systems return, quickly lowering comfort scores at elevation.
Best for: Crisp hiking days, improved visibility
Watch for: Rapid weather deterioration late season
For weather-focused planning at Hurricane Ridge, July is the best time to visit Olympic National Park, with August and September offering nearly as strong comfort and slightly less congestion. Visitors should remember that Olympic’s diverse terrain means conditions in rainforest valleys and along the coast can differ significantly from high-elevation ridge weather.
