Fire and water can steam or fizzle: passion meets sensitivity. In astrology the pair forms a square (three signs apart). Signs three apart share a modality but clash in element, a traditionally challenging aspect that creates friction and growth.

## At a glance

Traditional harmony rating: ★★☆☆☆ (based on the aspect between the signs). Real relationships depend on whole birth charts and, above all, on the people.

| --- | --- | --- |
| Dates | 21 March – 19 April | 21 June – 22 July |
| Element | Fire | Water |
| Modality | Cardinal | Cardinal |
| Ruling planet | Mars | the Moon |

## The two signs

Aries is described as bold, energetic and direct, the starter of things. Cancer is described as caring, intuitive and home-loving.

## In love

Intense attraction; fire must be gentle with water's feelings, water must not smother fire's independence.

Both are cardinal signs, so you share a way of approaching change, which can mean agreement or stubborn stand-offs.

## As friends

Rewarding if both are patient.

## At work

Works when roles are clear: fire leads, water reads the people.

## Tips for the pair

- Aries: appreciate Cancer's caring side.
- Cancer: appreciate Aries's bold side.
- Talk about needs directly rather than expecting your partner to guess.
