How GoodDayTo judges pressure washing
Pressure washing does not require perfect sunshine, but very cold weather, strong wind and persistent rain can make the job less practical. GoodDayTo looks for a usable daylight period and gives extra weight to conditions that help control spray and allow the surface to dry afterwards.
- Air temperature
- Rain probability
- Wind and gusts
- Daylight
- Drying conditions after the job
💦 Make the result practical
- Check whether pressure washing is appropriate for the actual surface before starting.
- Strong wind can send spray, dirt and chemicals where you do not want them.
- Local water restrictions, drainage rules and detergent requirements are outside the score.
Why weather still matters for a wet job
It may seem odd to care about rain when the job already uses water, but the weather affects comfort, visibility, spray control and drying afterwards. The model does not punish a tiny rain chance as aggressively as window cleaning, but heavy rain and strong wind still reduce the result.
Cold conditions deserve extra caution
Near-freezing conditions can leave wet surfaces slow to dry and may create ice later. The score therefore reduces very cold periods and severe winter precipitation. Equipment manufacturers can also specify operating-temperature limits that override this general weather screen.
What the pressure-washing score cannot know
GoodDayTo cannot judge surface strength, drainage, electrical hazards, chemical runoff, local restrictions, nearby people or whether your machine is suitable for the task. It is only a weather-planning aid for an outdoor cleaning job.
What the score means
GO means the weather factors GoodDayTo measures look favourable for this activity. WAIT means conditions are mixed or another upcoming window looks better. NOT TODAY means the forecast currently contains enough unfavourable weather signals that this is a poor choice. These are planning recommendations, not guarantees or safety clearances.
Frequently asked questions
Can I pressure wash in light rain?
Possibly. Light rain is not an automatic stop, but persistent rain can reduce comfort and make drying or cleanup less useful.
Why does wind lower the score?
Strong wind can blow spray, loosened dirt and cleaning products back toward you or onto nearby surfaces.
Why are cold conditions penalised?
Wet surfaces can stay cold and slow to dry, and freezing conditions can create additional hazards.
Does GO mean pressure washing is suitable for every surface?
No. Some surfaces, joints, coatings and materials can be damaged by excessive pressure. Follow manufacturer and surface guidance.
Does the app check water restrictions?
No. Local water-use, drainage and environmental rules must be checked separately.
