Sky weather is the practical version of "what is the sky doing right now." Cast a chart for any moment and any place, and the engine returns the calendar of upcoming aspects between the seven traditional planets, the sign changes those planets are about to make, and the dates when any of them will turn retrograde or direct. The seven planets are the working set because they are the ones whose aspects perfect inside a human planning horizon — outer-planet aspects take years.
When practitioners reach for this
The horary astrologer needs to know whether the Moon will perfect to its target before changing sign. The electional astrologer wants the calendar of inner-planet ingresses for the next two weeks before picking a date. The transit watcher wants to know when Mars stations, because the station week is the loudest one. The reading prep before a session benefits from a single-screen picture of what is happening overhead, so the client's transits land inside the right context. Sky weather is the one read for all four cases.
How to read each section
Applying aspects come first. The list is sorted by degrees_to_perfection, smallest first, so the next event in the sky is at the top. Each row tells you which planet is applying, which planet is being approached, the aspect type with its glyph, the current orb, the rough days-to-perfection estimate, and the sign where the aspect perfects. The Moon dominates this list because the Moon moves about 13 degrees per day; anything Moon-related at the top of the list is happening today or tomorrow.
Separating aspects are the same shape, with the smallest orbs first. A separating aspect is one that already perfected and is now widening. Read this list to see what just happened, which is often as useful as knowing what is coming — the Moon separating from Mars is the residue of yesterday's mood, the Sun separating from a square is the relief after the tension peaked.
Ingresses and stations
Sign ingresses are the moments when a planet leaves one sign and enters the next. They reset the planet's dignity, its rulerships, and the houses it triggers in any natal chart. Mercury into Gemini is loud for thinkers and writers. Venus into Cancer is loud for the mood of relationships. The ingress list shows the planet, the sign it is leaving, the sign it is entering, the degrees-to-ingress, and the rough days estimate.
Stations are the moments when a planet's apparent speed crosses zero — turning retrograde, then later turning direct again. The Sun and Moon never station, so they are excluded. Mercury stations are most frequent, three times a year for about three weeks each. Mars stations every two-plus years for ten weeks. The station week itself is the loudest part of the cycle, because the planet appears to stop in one degree of the zodiac for several days, intensifying the sign and house it occupies.
What sky weather is not
Sky weather is not a transit report. A transit report tells you which transiting planet is making which aspect to your natal chart. Sky weather tells you what the transiting planets are doing to each other. The two read differently and the two answer different questions. If you want personal timing, use the transit report calculator. If you want the shared sky calendar, you are in the right place.
Sky weather is also not horary. Horary picks one chart, the chart for the question, and reads it in detail with significators and considerations. Sky weather aggregates many small events into one calendar. The horary astrologer uses sky weather as background context; the horary judgment itself comes from the horary astrology calculator.
Pairing sky weather with electional work
The natural companion for sky weather is electional. The electional astrology calculator scores a date range for a specific activity and returns the best windows. Sky weather tells you why those windows are good — which planet is about to ingress, which aspect is about to perfect, which station is coming up. Run them side-by-side when planning a wedding, a business launch, or any decision that benefits from a chosen moment rather than an inherited one.
