Best time to visit — month-by-month guide for Seattle
Best time to visit Seattle for nice weather is July through August when conditions are warmest and driest; September is a good compromise with near‑summer weather and fewer crowds. If you prefer lower rates and far fewer tourists, visit between late October and early March, but expect more cloudy days and frequent rain.
In this guide

- Events, conventions, and weddings — plan around the downtown calendar

Summer: June–August — warm, sunny, and busiest
June through August is Seattle’s warm season and the driest stretch of the year. Expect the warmest daytime temperatures, more sunshine, and long daylight hours — ideal for waterfront walks, ferries, and outdoor seating near Pike Place Market.
Because this is peak tourist season, hotels including Sheraton Grand Seattle are typically busiest and rates often rise during weekends and city events. If you want skyline or water views, consider booking a room with a view early.
- Weather: warmest highs (August averages cited as the warmest month).
- Hotel perks: pool and Sheraton Fitness Center fully usable — pool on the 35th floor has panoramic views.
- Nearby activities: Pike Place Market, waterfront, Seattle Center attractions are most active.
| Month | Advantages | Notes for Sheraton Grand Seattle |
|---|---|---|
| June | Long days, fewer rain interruptions than spring | Good time for early-summer events; book ahead for weekend conventions |
| July | Sunniest month range; warm walking weather | Expect higher nightly rates |
| August | Warmest month on average; lots of outdoor festivals | Pool and fitness views are especially pleasant on clear days |
September–October — shoulder season with value and still-good weather
September often offers near-summer weather with fewer crowds and lower hotel rates after Labor Day. It’s widely recommended as a value month for good weather without peak-season prices.
October brings cooler temperatures and increasing cloudiness and rain, but it’s a quieter time to visit museums, restaurants like Alder & Ash and Vivienne's Bistro, and to attend indoor events at the Washington State Convention Center.
- September: best balance of weather, value, and lighter crowds.
- October: fewer tourists, good for cultural visits and indoor dining.
- Room tip: choose a Deluxe Room, City View or a Premium Room if you want city/window seating for fall light.
| Month | Crowds | Best for |
|---|---|---|
| September | Moderate → decreasing | Outdoor activities, lower rates than July/August |
| October | Light | Indoor attractions, quieter downtown walks |
November–March — low season: rainy, quieter, and better value
Seattle’s cool/wet season runs roughly November through March. These months bring more cloud cover and frequent drizzle, with November–January seeing many rainy days and January typically the cloudiest month.
This is the least crowded time at downtown hotels, so it’s a good choice if you want lower rates or need quiet business-travel days. Indoor hotel amenities — the heated indoor pool on the 35th floor and the bi-level Sheraton Fitness Center — remain available year-round.
- Expect more overcast days and rain; pack a waterproof layer and umbrella.
- Hotel advantages: lower room rates, more availability for specific room types and event space.
- Activities: museum visits, concert evenings at Benaroya Hall, and in-hotel dining (Alder & Ash, Vivienne's Bistro, Fountain Wine Bar).
| Month range | Visitor load | Why stay now |
|---|---|---|
| November–January | Low | Lowest crowds; be prepared for frequent rain |
| February–March | Low → picking up | Good hotel deals; early spring weather improving |
April–May — spring transition with more rain and rising activity
Spring is a transition: rain decreases compared with winter but still occurs more often than in summer. Blooming trees and longer daylight make this a pleasant time for city walks if you're prepared for variable weather.
Convention and meeting traffic can increase depending on event schedules at the adjacent Washington State Convention Center, so check local event calendars if your travel dates are flexible.
- April: variable weather; pack layers and rain protection.
- May: warmer and sunnier on average, crowds and rates begin to climb toward June.
- Booking tip: Sheraton Grand Seattle’s meeting and event spaces can be in demand in late spring — confirm availability for group travel.
| Month | Typical conditions | Who should travel now |
|---|---|---|
| April | Cool, often rainy | Museum-goers and travelers seeking lower shoulder-season rates |
| May | Warming, fewer rainy days than April | Those wanting earlier access to outdoor activities before peak season |
Events, conventions, and weddings — plan around the downtown calendar
Sheraton Grand Seattle sits adjacent to the Washington State Convention Center and has extensive meeting space across multiple ballrooms and the 35th-floor Cirrus Ballroom. Large conventions or weekend weddings can lift room rates and reduce availability.
If you’re attending or avoiding events, check the convention center schedule and the hotel’s event calendar when booking. For wedding guests or event planners, the hotel lists specific venues like the Grand Ballroom, Metropolitan Ballroom, and Cirrus Ballroom with varying capacities.
- Large conventions and trade shows typically raise downtown hotel demand—reserve early for specific room types (for example Room, Deluxe Room, City View, or Suite, 1 Bedroom).
- Cirrus Ballroom on the 35th floor offers panoramic views and is often used for receptions — ask event staff about timing to enjoy skyline vistas.
- For group bookings, contact the hotel’s event team to confirm meeting-room layouts and availability.
| Venue | Typical use | Capacity note |
|---|---|---|
| Grand Ballroom | Large conferences and receptions | Largest in-house ballroom; divisible sections available |
| Metropolitan Ballroom | Mid-size events, receptions | Used for conferences and weddings |
| Cirrus Ballroom | Receptions with views | 35th-floor venue with panoramic skyline/water views |
Booking tips, room picks, and on-site amenities
To maximize value and views, consider booking early for summer or large-event dates. If you want a city/window seat and city views of downtown, rooms such as Deluxe Room, City View, Premium Room, or Suite, 1 Bedroom are appropriate — confirm the specific view with the hotel when reserving.
