Helo gyfeillion y gwanwyn,

Mae’n amser diddorol i astudio ac arsylwi ar y tywydd! Bydd y rhan fwyaf ohonoch wedi gweld eira a gwyntoedd uchel yr wythnos ddiwethaf. Rwy'n deall bod llawer o ysgolion wedi'u cau, a hyd yn oed os oedd eich ysgol ar agor efallai ei bod hi’n rhy beryglus i gymryd darlleniadau tywydd.

Mae'n debyg byddwch chi wedi clywed pobl yn sôn am rybuddion tywydd dros yr wythnos ddiwethaf. Caiff rhybuddion tywydd eu rhyddhau gan swyddfa’r MET (gwasanaeth tywydd swyddogol y DU) gyda chod lliw (gwyrdd, melyn, ambr a choch) i ddangos pa mor eithafol fydd y tywydd mewn gwahanol ardaloedd.

Gwyrdd: dim tywydd garw.

Melyn: posibilrwydd o dywydd eithafol, gofalwch.

Ambr (oren): posibilrwydd cryf y bydd y tywydd yn effeithio arnoch chi mewn rhyw fodd, paratowch.

Coch: yn disgwyl tywydd eithafol, cynllunio ymlaen llaw a dilyn cyngor y gwasanaethau brys ac awdurdodau lleol.

Mae’r Swyddfa Dywydd hefyd yn defnyddio symbolau i ddangos pa fath o dywydd i’w ddisgwyl. Dyma symbolau yn dangos rhybudd coch am law, rhybudd gwyrdd am wynt ac eira, rhybudd ambr am iâ a rhybudd gwyrdd am niwl. Mae hyn yn golygu bydd hi'n bwrw glaw yn drwm a dylech chi baratoi am iâ. Beth am edrych ar y tywydd lleol ar wefan y Swyddfa Dywydd?

Yr wythnos diwethaf gwelodd rhai ardaloedd rybuddion ambr a choch ar gyfer gwynt, eira a rhew oherwydd storm Emma a’r 'Dihiryn o'r Dwyrain’. Mae swyddfa’r MET yn ein rhybuddio er mwyn i ni baratoi am dywydd garw. Gall tywydd garw (fel gwynt cryf ac iâ) achosi problemau a’i gwneud hi’n anodd teithio. Weithiau bydd ffyrdd, rheilffyrdd a hyd yn oed ysgolion yn cau oherwydd tywydd gwael.

Pa fath o dywydd weloch chi yr wythnos diwethaf? Os nad oeddech chi’n gallu casglu cofnodion tywydd, nodwch 'dim cofnod' ar y ffurflen, a dweud yn yr adran sylwadau pa fath o dywydd weloch chi! Gallwch chi hefyd roi gwybod sut hwyl sydd ar eich planhigion, ac a ydynt wedi blodeuo?

Daliwch ati gyda'r gwaith da gyfeillion,

Athro’r Ardd

Hi Professor Plant. Our crocus bulbs are mostly flowering now but our daffodil bulbs still have some way to go. This time last year we had lots of flowering daffodils so we think that all the snow we have had has made our bulbs slow to flower. Do you think it has been a cold winter this year?
