How GoodDayTo judges yard-sale weather
A garage sale, yard sale or car-boot-style outdoor sale needs more than one dry hour. Setup takes time, items may be exposed to the weather, signs can blow around and shoppers are less likely to linger comfortably in persistent rain or strong wind. GoodDayTo therefore searches complete multi-hour blocks and gives heavy weight to rain risk and gusts.
Temperature matters because both sellers and visitors may spend hours outside. Very hot or cold conditions reduce comfort even when the sky is clear. Strong sun can also be tiring during a long selling window, while darkness is treated as impractical for a normal daytime sale.
The score deliberately does not attempt to predict customer numbers. Weather can affect comfort, but turnout depends on location, promotion, local habits, competing events, the items for sale and many other factors GoodDayTo cannot measure.
Why a long window matters
A forecast that is dry at 09:00 but wet by 10:00 may be poor for a four-hour sale. GoodDayTo uses the duration you choose to evaluate the whole block, so a longer plan has to stay reasonably suitable instead of being rated from its best single hour.
Wind can be as disruptive as rain
Gusts can lift paper signs, move lightweight displays, knock over clothing racks or make a canopy harder to manage. The weather model therefore lowers the score as wind and gusts increase rather than treating any rain-free day as ideal.
What the score cannot know
GoodDayTo cannot check local permits, parking rules, pavement use, signage rules, homeowner-association restrictions, cash handling, security, shelter strength or shopper demand. Those practical and legal checks remain your responsibility.
- Rain probability
- Measured precipitation
- Temperature comfort
- Wind & gusts
- UV exposure
- Daylight
Practical checks before you go
- Protect paper, electronics and other weather-sensitive items even with a good forecast.
- Check local rules for signage, pavement use, parking and sale permits.
- Use the duration selector to match the real selling period, not only setup time.
Frequently asked questions
Can I use this for a car boot sale?
Yes. The aliases include car boot sale, but venue rules and event opening times must still be checked separately.
Does GO mean lots of buyers will come?
No. GO describes the weather fit only; turnout is not forecast.
Why can wind produce WAIT on a dry day?
Strong wind can make displays, signs, clothing racks and temporary shelter difficult to manage.
Can I plan several hours?
Yes. Use the duration selector or Planner so the whole selling block is evaluated.
Does a canopy or garage change the result?
Shelter can make a mixed forecast more workable, but GoodDayTo does not know how strong or weatherproof your setup is. Follow the manufacturer limits for canopies and move vulnerable items inside if conditions worsen.
